Question

Give reasons for the following statements : 

(a) The Sun does not rise at the same time everywhere in the world. 

(b) The speed of rotation at Leningrad (60°N), Genoa (45°N) and Singapore (0°N) along the Earth’s axis is not the same. 

(c) We do not feel the great speeds of Earth’s rotation in day-to-day life.

Answer 1

(a) The Sun does not rise at the same time everywhere in the world because earth is not a flat disc. 

(b) The speed of rotation at Leningrad (60°N), Genoa (45°N) and Singapore (0°N) along the Earth’s axis is not the same because of the spherical shape of the earth. 

(c) We do not feel the great speeds of Earth’s rotation in day- to-day life because the land, water and the air around the Earth are moving as a whole.
