Answers
Explanation:
1) There are 2 types of motion: Rotation and revolution
2) The speed of the Earth's rotation has affected the shape of the Earth. Because of the speed of rotation, a centrifugal force is created which leads to the flattening of the Earth at poles and bulging at the center. The Earth's rotation affects the movement of water in the oceans.
3)The circle of illumination is the division between day and night over the earth
4)Revolution is the term used to describe the path (or orbit) of Earth through space. Earth's revolution around the sun is responsible for seasonal change and leap years. This path is shaped like an ellipse and has points when Earth is closer to the sun and farther from it
5)The December solstice marks the start of winter
