(a) What is the true shape of the earth?
Ans: The true shape of the earth is geoid.
(b) What is a globe?
Ans: A globe is a miniature model of the earth that comes in different sizes. It is a very useful tool that helps us to study different continents and countries of the world.
(c) What is the latitudinal value of the Tropic of Cancer?
Ans: The latitudinal value of Tropic of Cancer is 23 ½0N.
(d) What are the three heat zones of the Earth?
Ans: Following are the important heat zones of the earth:
(e) What are parallels of latitude and meridians of longitude?
Ans: Parallels of latitudes: These are imaginary lines that runs from west to east. There are 180 total latitudes. The major parallels of latitudes are as follows:
Meridians of longitudes: Longitudes are also known as meridians of longitudes. These imaginary lines run from north to south. There are total 360 longitudes.
(f) Why does the Torrid Zone receive maximum amount of heat?
Ans: Torrid zone receives the maximum heat because the rays of sun directly strike this region. This zone is found between tropic of cancer and tropic of Capricorn.
(g) Why is it 5.30 p.m. in India and 12.00 noon in London?
Ans: India is located east of Greenwich at 82°30'E that is 5 hours and 30 minutes ahead of GMT. So it will be 5:30 p.m. in India when it is 12:00 p.m. noon in London.
