Answer:
Correct answers are:
1. (c) elliptical
2. (c) 24 I guess there is a mistake with the number
3. (c) rotation
4. (a) west to east
Explanation:
The shape of earth is ecliptic, it is not round because of the poles that are flattened.
Earth needs a little bit less than 24 hours to complete one rotation.
Rotation is movement that causes night and day, and revolution is Earth's movement around the Sun.
Earth rotates from west to east. That is why the sun comes out at the East.
