Earth's Rotation in One Hour
Earth rotates at an average speed of about 1,040 miles per hour (1,674.4 kilometers per hour) at the equator. This rotational speed decreases as you move towards the poles.

Calculating Earth's Rotation in One Hour
- To calculate how much degree Earth rotates in one hour, we need to first determine the circumference of Earth at the equator. The Earth's equatorial circumference is approximately 24,901 miles (40,075 kilometers).
- Next, we need to divide the Earth's equatorial circumference by 24 hours to find out how much distance Earth covers in one hour. This calculation gives us around 1,038 miles (1,669 kilometers) in one hour.
- Finally, we can convert this distance into degrees. Since there are 360 degrees in a full circle, Earth rotates approximately 0.004 degrees in one minute and 0.25 degrees in one hour.

Conclusion
In one hour, Earth rotates about 0.25 degrees. This rotation is responsible for the day and night cycle we experience on Earth. Understanding Earth's rotation is crucial in various fields such as geography, astronomy, and navigation.
