Answer:

Question 2.
Ramesh says “Earth is flat”. What do you say? (Conceptual understanding)
Answer:
Ramesh says’ “Earth is flat” thinking like the people who believed some four hundred years ago that the Earth was flat and that if anyone kept travelling in any direction, he would reach the edge of the Earth and from there he would fall off into the sky.

Some explorers of Europe set out on sea and knew that the Earth was not flat. Now we can say the Earth is like a ball – spherical in shape. The interesting thing about the shape of the Earth is that h’ travelling from one point in one direction we come to the same point without turning hack. So, will say strongly that the Earth is like a ball round. The photos taken from artificial satellites proved that the Earth is round.

Around 1400 AD, scientists and sea fare!m began to figure out that the Earth must be like a ball.

In 1485 Columbus, an Italian explorer travelled in Atlantic (can and reached some islands, If named them as West Indies.

Bartholomew Diaz, another sailor reached the African Cape Good Hope.
In 1498. Vasco-de-Gama sailed through the Cape of Good Hope and reached Calicut in India. Thus a direct sea route to India was discovered,
Another Italian sailor Anwrigo Vespucci explored further and discovered a continent. came to be known as America after him.
the travellers Corte and Pizzaro explored mans new places for Spain and .is a result of their efforts Latin America was discovered.

Answer:

Question 6.
‘The Sun always rises in the East’ – Find out the reasons for this. (Conceptual understanding)
Answer:
We all have learnt about the four directions i.e., East, West, South and North. We can locate the North and the South poles on the Globe. To the right side is the East and to the left side is the West.

The Earth rotates every day from the West to the East, By rotating the globe, we can understand that the sunrises in the East and sets in the West. By this, we can understand the sunrises in the East as we on the Earth moving towards East.

Question 7.
Why do we draw imaginary lines on the globe or map?(Conceptual understanding)
Answer:
We can see many lines crossing on the globe. Some run from the North Pole to the South Pole. While others run around the Earth from the West to the East. These imaginary lines drawn up by globe/map help us locate places on the globe and map.

Question 8.
What is the effort put up by scientists and sailors to know about earth? (Appreciation and Sensitivity)
Answer:

Earth is the only planet that support life as far as human knowledge is concerned.
The curiosity to know about shape of earth, other places present on earth, position and place of earth in solar system etc.. have been started in ancient centuries itself.
Waterways are the only cheapest and easiest way to travel long distances in earlier days, So, generally sailors started exploring new parts of the world and revealed them to outer world.
Gradually, normal people developed interest to know more about earth and used to start sailing in search of new facts about earth.
Such were the continents like America discovered by Columbus, Vascodagomas discover of route to India started new way of trade relations between Asia – Africa and Europe.
Several scientists also developed many scientific methods based on movement of earth in direction to sun, (rotation, revolution etc), observed geographical evidence etc., Eg: Continental drift theory of Alfred Weber.

Seas and Oceans stretch For hundreds and thousands of Kilometres – Just endless water. There are four great oceans named the Pacific, the Atlantic, the Indian and the Arctic Oceans.

The imaginary lines drawn on the globe from the West to the East are called latitudes. The longest of these lines is called Equator; it divides the globe into two equal halves. These imaginary lines drawn on the map help us locate places on the globe and maps.

Question 5.
What do you know about longitudes?
Answer:
The imaginary lines drawn on the globe from North Pole to South Pole are called longitudes. These lines are all of the same length. There are two main longitudes the Green Wich Line which is also called the Odegree longitude and the International Date Line.

Answer:
The Pacific ocean

Arctic Ocean.

Question 7.
How are the longitudes and latitudes useful to us?
Answer:

Longitudes help us to calculate time.
The longitude running through the Greenwich near London is known as the prime meridian having the same time at all places on the Earth.
Together the latitudes and longitudes create a net that covers the map and helps us to locate the places.

Question 8.
What would happen if there are no longitudes and latitudes,
Answer:
We cannot know time perfectly. We can not locate distant places particularly while travelling in aeroplanes.
