Answer 1

1. Uranus is called a somersaulting planet due to its tilt axis tilt which is about 98 degrees relative to the orbit of earth around the sun. If you stand close to the equator of Uranus, the sun will seem to move in some sort of circular path.

2. The surface of moon comprise of numerous craters due to constant collision with asteroids and meteorites. The moon is devoid of an atmosphere to protect itself.

 3. An object at the equator has a relative velocity in comparison to objects at the poles. This is also one of the reasons why effective velocity at poles is zero.

Answer 2
