- The Earth makes a full rotation of 360 degrees about its axis in approximately 24 hours.

- To find out how many degrees it rotates in one hour, you divide 360 by 24.

- Calculation: 360 degrees ÷ 24 hours = 15 degrees per hour.

- This means the Earth rotates about 15 degrees in one hour.

Let's review the options:

- Option 1 (10 degrees): Incorrect, as the Earth rotates more than this in one hour.

- Option 2 (20 degrees): Incorrect, this is more than the Earth rotates in one hour.

- Option 3 (15 degrees): Correct, the Earth rotates exactly 15 degrees per hour.

- Option 4 (24 degrees): Incorrect, this number doesn't align with the 24-hour rotation cycle.
