Question 1.
What are the components of a map?
Answer:
The components of the map are

1. Directions,
2. Scale,
3. Symbols and
4. Colours.

Question 2.
Why is the actual distance on the ground reduced on a map?
Answer:
It is impossible to draw a map showing actual distances. So we use ‘scale’ to show the actual distance on the ground in a reduced manner on a map.

Question 3.
Explain the need for symbols in preparing maps.
Answer:
Maps are too small for us to draw pictures of the things shown on them. For example, we can’t draw the real school or a bus stand or a tree as they will take too much space on the map. Therefore, we always show things with the help of symbols on the map.

Question 4.
Find out the scale used in your district map to show the distance between your Mandal headquarter and district headquarter?
Answer:
Student Activity (One example is given for you).
Ex: Our mandal is Agiripalli. It is in the Krishna district. Our district headquarter is Machilipatnam.
On the map, the scale is given as 1 cm = 10 km.
The actual distance from Agiripalli to Machilipatnam is 83 km.
The distance between Agiripalli to Machilipatnam is 8.3 cms on the map.

Question 5.
How political maps are different from physical maps.
Answer:
Political maps show territorial features like country, cities, nations, and their boundaries. A physical map indicates the natural features of a place like mountains, water bodies, plains, etc.

Question 6.
What is the importance of thematic maps?
Answer:
A thematic map shows the spatial distribution of earth surface features. Thematic maps are used to display geographical concepts such as density, distribution, relative magnitudes, gradients, spatial relationships and movements. These maps focus on specific information like the map of rainfall, roads, tourist places etc..

Question 7.
What are the uses of maps in our daily life?
Answer:
Maps help us in many ways in our daily life. They help us to understand the concept of a subject.

1. Maps help us to locate places like cities, districts, states and countries.
2. Maps show the physical features such as mountains, plateaus, plains.
3. Maps help us to know the major routes of transport such as roads, railways, etc.

AP State Syllabus 6th Class Social Studies Solutions 2nd Lesson Globe – Model of the Earth

6th Class Social Studies 2nd Lesson Globe – Model of the Earth Textbook Questions and Answers

Improve Your Learning

Question 1.
What is a globe?
Answer:
Globe is a true model of the Earth.

Question 2.
What are the movements of the Earth?
Answer:
Rotation and Revolution are the movements of the Earth.

Question 3.
Which movement of the Earth causes Day and Night?
Answer:
Rotation of the Earth causes Day and Night.

Question 4.
What happens when the Earth rotates?
Answer:
During rotation, half portion of the Earth receives Sun’s rays and the remaining half portion remains in darkness.

Question 5.
Define the Earth’s Rotation and Revolution.
Answer:
Rotation: Planet Earth rotates around itself on its own axis. This movement is called Rotation.
Revolution: Planet Earth rotates around the Sun. This movement is called Revolution.

Question 6.
What is the true shape of the Earth?
Answer:
The Earth is round in shape. The Earth is slightly flattened at the poles and bulges in the middle or at the equator.

Question 7.
Which Latitude is known as the Tropic of Cancer?
Answer:
The latitude which is located at 23\(\frac{1}{2}\)° north of the equator is known as the Tropic of Cancer.

Question 8.
Read the Paragraph under the title ‘Equinox’ and comment on it.
On 21st March and September 23rd direct rays of the Sun fall on the equator. At this position, neither of the poles is tilted towards the Sun. So, the whole earth experiences equal days and nights. This is called an equinox.
On 23rd September, it is autumn season in the Northern Hemisphere and spring season in the Southern Hemisphere. The opposite is the case on 21st March when it is spring in the Northern Hemisphere and autumn in the Southern Hemisphere. Thus, you find days and nights and changes in the seasons because of the rotation and revolution of the earth.
Answer:
On 21st March and 23rd, September Sun’s rays fall directly on the Equator. So we experience equal day and night on both these days. This is called equinox. On 21st March it is autumn in the Northern Hemisphere and spring in the Southern Hemisphere. Because of Earth’s rotation, half portion of the Earth receives Sun’s rays and the remaining half remains in darkness. So we find changes on Earth because of Earth’s rotation and revolution.

Question 9.
Create a table and list out the similarities and differences between Latitudes and Longitudes.
Answer:
Similarities between latitudes and longitudes:

1. Latitudes and longitudes are both artificial.
2. Latitudes and Longitudes are both invisible lines.
3. Latitude is based on the 0° latitude while longitude is based on Greenwich.
4. They both help us to locate a place on earth

Differences:

Latitudes	Longitudes
1) Latitudes are the horizontal lines.	1) Longitudes are vertical lines
2) Lines of latitudes are parallel to the equator.	2) Lines of longitude are not parallel and come to a singular point.
3) Latitudes lines run in the East and West directions.	3) Longitude lines run in the North to South direction.

Question 10.
If India has day, it is night in America. What is the reason for this difference?
Answer:
The part of the Earth that faces the Sun gets illuminated and experiences the day. The opposite part of the earth that does not face the Sun, experiences night. As India is opposite to America the difference in day and night occurs.

Question 11.
Take a ball and draw the latitudes and longitudes on the surface.
Answer:
Project Work: Student Activity.

Question 12.
Prepare a note on the difference between a globe and an atlas.
Answer:

1. A globe is a three-dimensional sphere. An atlas is two-dimensional.
2. A globe represents the whole earth. An atlas represents the whole earth or a part of it.
3. A globe can be used to get a broad-level picture of the world. An atlas provides more specific information about different places.

Question 13.
Find out the latest leap year and the coming leap year.
Answer:
The present year 2020 is a leap year. 2024 is the coming leap year.

Question 14.
What preparations should be taken to watch a solar eclipse safely?
Answer:
The Sun outputs more power than our eye is designed and so it damages the retina. So we should not watch the Sun or the solar eclipse directly. We should use special-purpose solar filters, such as eclipse glasses to watch Solar eclipses safely. Projecting the Sun through a box projector is another safe way to watch the solar eclipse.

Question 15.
It is difficult to understand the geographical location, time, and distance in the absence of the imaginary lines – latitudes and longitudes. Appreciate the design of the imaginary lines of latitudes and longitudes.
Answer:

1. Latitudes are used to define the North-South position of a location on the planet.
   The general climatic division of a place can be studied with the help of latitudes.
2. Longitudes are used to define the East-West position of a location on the planet. Longitudes also help us to calculate the time of a particular place.
3. If the latitude and longitude are known any position on earth can be located. Even- though, longitudes and latitudes are imaginary lines they play an important role.

So we should appreciate the design of the imaginary lines of the latitudes and longitudes.

Question 16.
Venu met some children from different cities at a youth festival. They were: Geethika, John, Nihal, and Uma. Venu collected some information about their cities.
Venu has given us certain clues. Can you find out the cities with the help of an Atlas?

  Find and write the city name: (Kolkata)

Question 17.
If an astronaut from a spaceship looks down at the Earth, can he/she see the rotation of the earth?
Answer:
Yes. From a spaceship, an astronaut can see the rotation of the earth. Spaceships move around the Earth at a different speed. So the astronaut can see the Earth’s rotation.

Question 18.
Why can’t we sense the rotation and revolution of the Earth?
Answer:
The Earth is moving at a fixed speed and we are also moving along with it at the same speed. That is why we can’t sense the Earth’s spin. If Earth’s spin changes we would definitely sense it. If we are in a car that is moving at a constant speed on a smooth surface, we will not know that we are moving. However, when the car accelerates or when the brakes are applied, we will feel the motion. Another example is, we can drink coffee or tea on a moving train which is moving at a constant speed* because we are traveling by train at the same speed. If the speed of the train changes we can’t drink. The spin of Earth doesn’t make those kinds of changes. So we can’t sense the rotation and revolution of the Earth.

Question 19.
Choose the correct answer.
i) The movement of the Earth around the Sun is known as
A) Rotation
B) Revolution
C) Inclination

(Textbook Page No. 16)

Question 1.
How does the earth rotate and revolve without any needle, unlike the Globe? Discuss with the teacher.
Answer:
Our Solar System formed about 4.6 billion years ago when a huge cloud of gas and dust started to collapse under its own gravity. As the cloud collapsed, it started to spin. The Solar system is made up of the Sun and everything that orbits around it includes the planets and their moons as well as numerous asteroids, meteoroids, and comets. Without any unbalanced forces acting on them, the tremendous gravity of the Sun and the planets have kept them rotating for billions of years. Either the Earth or any other planet does not have any needle to rotate or to revolve.

Question 2.
All the celestial bodies are round in shape. Why?
Answer:
A planet is round because of its gravity. Gravity pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of a planet a sphere, which is a three-dimensional circle.

(Textbook Page No. 17)

Question 3.
In which hemisphere is India located?
Answer:
India is located within both the Northern and Eastern hemispheres.

Question 4.

Arctic Ocean	Southern Ocean	Pacific Ocean Atlantic Ocean Indian Ocean

Question 7.
Why do latitudes get smaller towards the pole? Which latitude is the biggest circle?
Answer:
The equator is the largest circle and divides the globe into two equal halves. So it is at the center of the Earth. Circles of latitude are all great circles with the center of Earth in the middle. The circles of latitude get smaller as the distance from the Equator increases. So the latitudes get smaller towards the poles. The Equator is the biggest latitude.
