TS 6th Class Science Important Questions 3rd Lesson Rain: Where Does it Come From?

Question 1.
What are the three forms of the water?
Answer:
Water on the earth can exist in 3 forms:
Ice (solid form), water (liquid form) and water vapour (gaseous form).

Question 2.
Define the following. Give suitable examples.
1. Evaporation
2. Condensation
(Or)
What is the process in which water changes to water vapour?
Answer:
1. Evaporation : The process of changing of water into water vapour is called evaporation.
Eg: Cloud formation.
2. Condensation : The process of conversion of water vapour into water is called condensation.
Eg: Formation of rain.

Question 3.
What causes rain on the earth?
Answer:
The cycle of evaporation and condensation of water, present on the earth’s surface, causes rain.

Question 4.
What is water cycle?
Answer:
The conversion of water into water vapour, water vapour to clouds, clouds to rain is known as water cycle.

Question 5.
Write a few lines about the cause of floods or droughts.
Answer:

• Deforestation and pollution from factories are now causing global warming.
• So, the atmospheric conditions are not favourable for clouds to get cooled.
• Consequently, there is a decrease in the rainfall. This leads to disturbance of water cycle and causes either floods or droughts.

Question 6.
Write the changes that take place in the following blank.

Answer:

Question 7.
In our state rains occur normally from June to September. What is the name of this monsoon?
Answer:
In our state rains occur normally from June to September.

• During that season we observe in the sky that clouds move along with the winds blowing from western directions.
• These winds are called “south-west monsoon”.

Question 8.
Explain north east monsoon and south-east monsoon.
(Or)
What is meant by north-east monsoon ? In which season the rain occurs due to north east monsoon?
Answer:

• Generally, we get rains in some particular months during the year.
• In our state, rains occur normally from June to September.
• During that season you might have observed in the sky that clouds are moving along with the winds blowing from western direction (south west side).
• These winds are called “south west monsoon”.
• Similarly, we observe in the months of November and December rains occur due to movements of clouds in the direction of winds blowing from eastern side (north-east side).
• These winds are called “north-east monsoon”.

Question 9.
Explain various forms of water with suitable examples.
(Or)
In how many forms water exists on the earth? How does water convert from one form to another?
Answer:
Water is available in 3 forms

• Solid
• Liquid
• Gaseous

Solid form of water: Solid form of water is ice. The lowest temperature below 0°C converts water into ice. Eg: Ice cubes in fridge

Liquid form of water: When ice melts it will change into water, normal temperature converts the ice into liquid. Eg: Water in rivers, lakes, oceans

Gaseous form of water: The gaseous form of water is water vapour which is present in the air around us. Eg: Water vapour releasing from boiling vessel.

Question 10.
Describe the various stages of water cycle? Explain what changes will occur in water cycle due to deforestation.
Answer:
Definition : The circulation of water into water vapour by evaporation, water vapour to clouds and clouds to rain by condensation is known as water cycle. When it rains water bodies are filled with water. Some of this rain water seeps into the ground and becomes ground water.

As it is very hot during summer, large quantity of water evaporates from water bodies and converts into water vapour. This goes up into the air to form clouds. These clouds again cool and produce rain.
Deforestation and pollution from factories cause global warming.

Therefore atmospheric conditions become unfavourabie for cooling of clouds. Consequently there will be decrease in rainfall. This disturbs the water cycle and causes either floods or droughts.

Question 11.
Suppose you heard that there is raining in some area, but at the same time there may not be raining in other area. Why is it so?
Answer:

• Often we see that there may be rain in some area, where it may not be in its adjacent areas.
• This is because of condensation of clouds due to cool air which affects them in the specific area.
• Occurrence of winds won’t be same in all the areas. Pressure influences the presence of air.
• Clouds along with winds move from high pressure area to low pressure area at which cool air occurs.
• That’s why rain is seen only in some areas, where we can’t see it in its adjacent areas.

Question 12.
If there is no evaporation and condensation (or) in the nature what would happen. What are the consequences of decrease in rainfall?
Answer:
Absence of evaporation and condensation in the nature causes Jack of rainfall.
Consequences that occur due to lack of rains or less rain fall.

• Fertile lands become unfit for harvestation.
• Water scarcity occurs.
• Rain based agriculture will face many problems. As a result, crops and plants will not grow.
• Global warming will affect the earth.
• Plants will die in every region.

Question 13.
What questions do you ask a meteorologist to know about clouds?
Answer:

• Why are clouds formed only in the sky?
• How are clouds formed?
• Why do we have rains only in some seasons?
• Why don’t we have rains in summer?

Question 14.
In winter mornings we observe small dew drops on grass leaves. What is this process?
Answer:
Especially during winter water vapour present in the air cools down due to cold weather. Therefore condensation occurs and as a result water vapour appears in the form of dew on the leaves.

Question 15.
Though it is rainy season, we are not getting enough rains. To find out the reason, what questions do you ask your teacher?
Answer:

• Why do not we have sufficient rains?
• What are the reasons for less rains?
• Who are responsible for having less rains?
• What should we do to have good rains?

Question 16.
What changes are seen if there is no occurrence of condensation in the water cycle? (Or) What happens if evaporated water does not condense?
Answer:
If there is no occurrence of condensation in the water, water cycle stops due to lack of rains.
If there are no rains water sources will not be filled with water. Even ground water level decreases. Low percentage of water levels in the natural water bodies cause damage to the living kingdom, thus it finally leads to destruction of nature. Hence condensation process is very essential in the water cycle.

Question 17.
“Clouds lead to falling of rains.” :
There are some other concepts like above in the lesson. Find out and write them.
Answer:
Some important concepts:

• Three forms of water are interchangeable.
• Evaporation is the process of water into water vapour.
• Condensation is the process of water vapour into water.
• The circulation of water in three forms in the nature is called water cycle.

Question 18.
Frame three innovative questions on the following.
1. Evaporation
2. Condensation
Answer:
1. Evaporation:

• What is the importance of evaporation?
• How do we get clouds due to evaporation?
• Where do you find evaporation?

2. Condensation:

• Where do we see condensation?
• Define condensation.
• What are the uses of condensation?
• What is the relation between rains and condensation?

Question 19.
What happens if size of the evaporated water molecules increases in the cloud?
Answer:
If size of the water molecules in the cloud increases, they convert into water droplets and condense to form rains.

Question 20.
Explain the procedure to prove the conversion of water vapour into water. (OR) What is condensation ? How do you prove the process by condensation?
Answer:
Definition : The process of conversion of water vapour into water is called condensation.
Procedure:

• A vessel is taken and filled with water.
• It is kept on a stove and heated slowly.
• It is observed for sometime. Now the vessel is covered with a plate.
• The plate is removed after a couple of minutes.

Question 21.
Explain the procedure to be followed in the experiment condensation.
(OR) When we poured cool (water) drink in a glass, we observed water droplets on the outer surface of the glass. Why?
Answer:

• Ice cold water in the glass cools its surface.
• Air around the glass contains water vapour which is warmer than the surface of the glass.
• Due to the cold glass, air close to its surface will also become cooler.
• This changes the water vapour in the air around the surface of the glass into water and forms small drops on the outer surface of glass. It occurs if there is only either ice or cold water.

Question 22.
You feel happy while raining. Ask any two questions to your teacher to clarify your doubts on raining.
Answer:

• How do rains fall?
• Why don’t we see rains in all the seasons?
• Rain falling in one place is not seen in other place. Why?
• How does rain start in the sky?

Question 23.
Read the information given below and answer the questions.
We call solid form of water ice. Snow occurs naturally. If we heat ice, it will change into water. Water in liquid form ¡s present in oceans, seas, lakes, rivers and even underground. The gaseous form of water is water vapour which is present in the air around us. We know that when ice is heated, it converts into water and if water is heated it turns into water vapour. Similarly when water vapour is cooled we can get back water. If water is cooled further we get ice.

1. Name few sources of water in liquid form.
Answer:
Oceans, seas, rivers etc.

2. How do you interchange the three states of water?
Answer:
Solid form of water (ice) is heated to convert into liquid state. Liquid form of water is further heated to convert into water vapour.
Ice ← Water ← Water vapour

3. Name the process which converts water into water vapour.
Answer:
Evaporation

4. Where do you find solid ice in nature?
Answer:
Polar regions and glaciers

Question 24.
Visit your school library or internet, collect information about (Kashmir) Dal Lake. In which season water in the lake becomes ice and snow fall is very high and why the place attracts more tourists?
Answer:
Project Work on Dal Lake :

• Dal Lake is the beautiful, naturally formed resource in the Kashmir valley.
• To obtain information about it, I collected necessary points by visiting internet.
• Dal Lake premises are the famous tourism hub for so many visitors all over the world.
• During winter (between December and February) Dal Lake freezes due to freezing atmosphere with minus degree celsius.
• It forms like solidified ice snow area due to freezing conditions.
• It looks like a playground during freezing winter season.
• During summer, it shows beauty of the nature of Kashmir in the name of boating etc.

Question 25.

In the given diagram you can observe droplets of water on the surface of ice containing glass.
1. Why are those drops formed?
2. Do they form if there is no ice in the glass?
Answer:

• Ice cold water in the glass cools its surface.
• Air around the glass contains water vapour which is warmer than the surface of the glass.
• Due to the cold glass, air close to its surface will also become cooler.
• This changes the water vapour in the air around the surface of the glass into water and forms small drops on the outer surface of glass. It will occur if there is only either ice or cold water.

Question 26.
Draw the diagram of showing water cycle on the earth and label it.
Answer:

Question 27.
Draw the diagram of water cycle and write a note on it.
Answer:

Definition: The circulation of water into water vapour by evaporation, water vapour to clouds and clouds to rain by condensation is known as water cycle.

When it rains water bodies are filled with water. Some of this rain water seeps into the ground and becomes ground water. As it is very hot during summer, large quantity of water evaporates from water bodies and converts into water vapour. This goes up into the air to form clouds. These clouds again cool and produce rain.

Question 28.
Harsha appreciated that the nature is a great gift of giving rain. How can you appreciate It?
Answer:
Nature is the great gift of giving rain.

• Hills stop the clouds and cool them and give sufficient rains.
• Forests in the nature stop the clouds and convert them into rains.
• The entire nature is like heaven to sustain our life by giving rains seasonally. Therefore we should protect this precious environment.

Question 29.
How do you appreciate the contribution of water cycle in making the water available for various needs of plants and animals?
Answer:

• When it rains ponds, lakes etc., are filled with water.
• Water from rainfall runs down as small streams. :
• These small streams join together arid make bigger streams. These bigger streams join the rivers.
• The rivers flow down to seas and oceans. Some of this rain water seeps into the ground and becomes ground water.
• The plants and mima1s depend on water bodies such as ponds filled with rain water.
• The water bodies are ponds, lakes, streams, rivers, seas and oceans.
• All the living things sustain their life by utilizing water resources.

TS Board TS 6th Class Science Study Material Pdf 15th Lesson Light, Shadows and Images Textbook Questions and Answers.

TS 6th Class Science 15th Lesson Questions and Answers Telangana – Light, Shadows and Images

Question 1.
Classify the following objects into transparent, translucent and opaque:
Cardboard, duster, polythene cover, oily paper, glass, spectacle lens, piece of chalk, ball, table, book, window glass, palm, school bag, mirror, air, water. Which type of materials do you find more in your surroundings?
Answer:

Transparent objects	Translucent objects	Opaque objects
Glass, Air, Spectacle lens	Polythene cover, Oily paper, Window glass, Water	Cardboard, Mirror, Piece of chalk, Bail, table, Book, Palm, School bag, duster

I find opaque materials more in my surroundings.

Question 2.
Hold a glass slab at one end with your hand and stand in sunlight. See the shadows of your hand and glass slab. Explain what you observed.
Answer:

• We can see the shadow of our hand on the ground.
• We can not see the shadow of glass slab.
• Glass slab is transparent and so sunlight passes through it without forming its shadow.

Question 3.
We cannot identify the presence of completely transparent objects even in the light. Is it correct or not? Support your answer.
Answer:
Yes, we cannot identify the presence of completely transparent objects even in the light.
Eg:

• Air cannot be seen.
• Light transmitted through certain matter like air doesn’t reach our vision.
• I can support the given statement.

Question 4.
Why can’t we see objects which are behind us ?
Answer:

• Our body is opaque. Light cannot pass through it.
• So the light reflected by those objects does not reach our eyes.
• So we can’t see the objects lying behind us.

Question 5.
If we focus a coloured light on an opaque object, does the shadow of the object posses colour or not? Predict and do the experiment to verify your predictions (coloured light can be obtained by covering torch glass with transparent coloured paper)
Answer:

• The shadow is not coloured. It is dark only.
• Because, a ‘shadow’ means, ‘absence of light of any colour’.
• Shadow is colourless irrespective of colour of the object.
• It is predicted and proved correct after verifying the experiment.

Question 6.
Between an electric bulb and a tube light, which forms sharp shadows of objects? Do experiment to find and give the reason.
Answer:

• Electric bulb forms sharp shadows of objects.
• A tube light cannot form sharp shadows of objects.
• The same thing is proved correctly after doing the experiments.
• Bulb light is a point source of light and it forms sharp shadow of the object.
• Tube light is an extended source of light and so it cannot form sharp shadows of objects.
  (Note: Bulb = filament bulb)

Question 7.
What is required to get a shadow of an opaque body?
Answer:
Three things are required to get a shadow of an opaque body.

• Source of light
• Opaque object
• Screen

Question 8.
How can you explain the straight line motion of the light?
Answer:

• Light travels in a straight line. That is why, when opaque objects obstruct the light, their shadows form.
• We can predict the shapes of the shadows only when we consider that light travels as rays along a straight path.
• Formation of an ‘inverted image’ on the screen of the pinhole camera explains that light travels in a straight line.

Question 9.
Explain, what happens if the size of the hole in a pinhole camera is as big as the size of a green gram ? Increase the size of the hole in pinhole camera and look at any object with that camera. What do you find ? Write reasons for that.
Answer:

• If the size of the pinhole camera is as big as the size of a green gram, the sharpness in the image decreases.
• The image becomes thick and the details of the image are not visible.
• As the size of the hole increases more light enters and disturbs the formation of the image.

Question 10.
Draw the shadows in your note book for the objects given below assuming that the light source is exactly above on these objects.
Answer:

Question 11.
Where do you find reflection of light in your daily life ? Write few examples.
Answer:

• The image of our face in the plane mirror is due to reflection of light.
• The visibility of object in and around us. :
• The moon is visible to us because it reflects the sunlight.

Question 12.
We would not be able to see any object around us if light does not get reflected. How do you appreciate this property of objects?
Answer:

• Objects are visible only when light falls on it gets reflected and reaches our eye.
• In darkness the objects are not visible as no light reaches our eyes from the objects.

Question 13.
Can we use a plain mirror as a rearview mirror? If not, why?
Answer:

• We can’t use a plain mirror as a rearview mirror.
• It can’t give a full rear view. So a convex mirror is used.
• The convex mirror gives a small erect image.
• Convex mirror has a capacity of minimising the rear object and catch in it.

Question 14.
A mirror is kept on the wall of your room. Your friend is sitting on a chair in that room. You are not visible to him in the mirror. How do you adjust your place so that you are visible to your friend in the mirror? Explain.
Answer:

• Suppose my friend is sitting to the left side of the mirror fixed on the wall, at a distance.
• Then I move to the right side of the mirror, till I am visible to my friend.
• I sit in a position to fall incident ray from me onto the mirror.

Question 15.
Why do we get shadows of different shapes for same object?
Answer:

• We can get shadows of different shapes for the same object, by changing its position.
• Reason: It is because, light travels in a straight line path, in that path only shadows form.

Question 16.
What are the differences between a shadow and an image?
Answer:

Shadow	Image
1. Shadows are not coloured.	1. An image has colours that are same as that of the object.
2. A shadow shows only the outline of the object.	2. An image shows the complete object as it is, just like a photograph.
3. Sometimes we may not be able to guess the object by observing its shadow.	3. We can indirectly see the object, in the mirror.
4. Position of the shadow changes with the change in the position of the source of light.	4. This is formed due to reflection of light.
5. A screen is required to catch the shadow.	5. No such thing is required.

Question 17.
Malati noticed changes in lengths of her shadows during the day time. She got some doubts about this. What could be those doubts?
Answer:
Possible doubts Malati may get.

• From morning to noon (12 o’clock), the length of my shadow decreased gradually. Why so?
• The position of my shadow also changed. Why so?
• At noon, my shadow is just below me. Why so?
• Again after the noon, the length of my shadow went on increasing with time. Why so?
• The position of my shadow also changed, Why so?
• Though I did not change my position, my shadow changed positions.

Question 18.
Observe the light source and mark the place where the screens should be kept to get the shadows of the objects given below.

Answer:

• Screens should be placed at a distance from the objects.
• They should be placed just opposite to the light source.

TS 6th Class Science 15th Lesson Notes Light, Shadows and Images

• We cannot see the objects in the absence of light.
• We can see an object only when light falls on it, bounces back and reaches our eye.
• Any object which burns or glows acts as a source of light.
• We need light to get the shadow of any object,
• We need a source of light, an opaque object and a screen, to form shadows.
• In many cases, we cannot guess the object by observing its shadow.
• Colour of objects cannot be determined by looking at their shadows.
• Shadow is always dark, whatever be the colour of the object.
• Light travels in a straight line. So shadows are formed.
• By changing its position, we can get shadows with different shapes for a single object.
• In a pinhole camera, we get an inverted image of flic object.
• An image is different from a shadow.
• Light : It is a form of energy, which is released from sources of light such as sun, moon, bulb, candle etc.
• Sources of light : A substance which gives light is known as a source of light. Eg : sun, moon, bulb, etc.

• Shadow : A dark shape produced by an object on the effect of light rays. Shadows are formed when opaque objects obstruct the path of light.
• Transparent substances : The substance which we can see through is called transparent substance. They can not form shadows. Eg : air, glass etc.
• Opaque substances : The substances through which we can not see it are called opaque substances. These can form shadows. Eg : cardboard, wall, etc.
• Pin hole camera : A camera through which we can observe a big object through a pinhole (very small hole). We get an inverted image in pinhole camera.
• Image : An image is a picture of someone or something.
• Reflection : When light falls on any object, it bounces back. This process is called reflection.
