Question

Answer the following questions in detail:
1. What do you understand by two kinds of movements of the earth? Discuss revolution of the earth.
2. What would happen if the axis was not tilted?​

Answer 1

Answer:

1.The second is the revolution around the Sun. ... The two main movements of the Earth are the rotation of the Earth around its axis (it takes 24 hours to complete one rotation), and the revolution of the Earth, or orbital motion, around the Sun (which takes 365 ¼ days, or 1 year, to complete).

2.If the Earth weren't tilted on its axis, there would be no seasons. And humanity would suffer. When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant.
