Give reasons for the following statements : (a) The Sun does not rise

1.	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» (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.

(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.
