C Answer these questions.
1. How was it proved that the Earth is spherical in shape?
2. How is a globe useful to us?
3. How do maps help us? Why is a map less accurate than a globe?
4. What are the features that help us to read a map?
Answers
1.The Earth is massive enough that the pull of gravity maintains its roughly spherical shape. Most of its deviation from spherical stems from the centrifugal force caused by rotation around its north-south axis. This force deforms the sphere into an oblate ellipsoid.
2.It shows the distribution of land and water on the surface of the earth.
It shows the correct shape, size and location of the continents and oceans on globe.
3.Maps help us in finding out the distances and give us the information of how far we are from our destination. ... A map is a copy of the globe on a flat paper whereas A globe is round in shape and is the exact copy of the planet Earth. So, a map is less accurate than a globe.
4.The scale, symbol, and direction are important tools that help you to read the map conveniently. The map is used for showing as well as recording the information such as relief features, social feature, political boundaries and others.
Explanation:
No. 1 answer is
Long long ago, people believed that the shape of the earth is flat. But Ferdi and Magellan took a long journey by sea around the earth and proved that the earth is round. Later, many pictures of Earth were taken from space.
No. 2 answer is
Globe is useful because it is a true model of Earth. Its shape and size is also similar to Earth. It displays many things which are in the earth like continents, country, river, sea, lakes even state in the same position as they are. At a time we can only see half of a globe but we can rotate it to see the another.
No. 3 answer is
Maps also helps us in many ways such as
It also show us continents, country, river, sea, state as accurate. Other than it show us the physical Ana political features.
Yes, a map is slightly less accurate than globe because a map is drawn on a flat surface like paper. A curved surface can not be drawn exactly on a paper. So in map there are some mistakes or errors in the shapes and size of land masses.
No. 4 answer is
There are many features that helps us to read a map such as Title, direction, scale, signs and symbols and colours
Title :- Every map has a title that tells us what the map is about.
Direction :- There are four directions helps us to know that in which direction is the country or state is located. And that four directions are North, South, East and West.
Scale:- scale on a map helps to represent the actual distance. The ratio between distance on the ground and distance shown on the map.
Signs and symbols :- signs and symbols helps to locate lakes, river, sea, forts, temples, railway station etc.
Colours :- colours are usually to show different physical features on a map such as mountain, river, sea, forests, plain etc.
Blue- it shows water bodies.
Green- it shows plains.
Red- it shows urban ares, highways, military sites, airports, buildings etc.
Yellow- it shows deserts.
Brown-it shows hills and mountains area.
Black- it shows cities, roads, railway tracks etc.
