Solution Steps

Step 1: Understanding the Earth's Rotation

The Earth's rotation refers to the spinning of the Earth around its axis. This rotation is responsible for the cycle of day and night.

Step 2: Identifying the Time Unit

The time unit that is directly based on the Earth's rotation is the "day." A day is defined as the time it takes for the Earth to complete one full rotation on its axis.

Step 3: Comparing with Other Time Units
  • A month is based on the lunar cycle, which is the time it takes for the Moon to orbit the Earth.
  • An hour is a subdivision of a day, not directly based on the Earth's rotation.
  • A year is based on the Earth's orbit around the Sun.

Final Answer

The unit of time based on the rotation of the Earth is the \(\boxed{\text{day}}\).
