Complete the following math problems related to Earth's rotation on its axis.
- What is the circumference of the Earth at the equator? (Use the formula C = 2Ï€r, where r is the radius of the Earth, approximately 6,371 kilometers)
- If the Earth completes one full rotation on its axis approximately every 24 hours, how many rotations does it complete in 30 days?
- If a point on the equator travels approximately 40,075 kilometers in one rotation, what is the speed of a point on the equator in kilometers per hour? (Hint: Divide the total distance by the time in hours.)
- Explain, in your own words, how the tilt of the Earth's axis affects the seasons.
- List two effects of the Earth's rotation on its axis.
