5.8C Earth's Rotation

Front

What is Earth's rotation?

Back

Earth's rotation is the spinning of the Earth on its axis, which takes about 24 hours to complete one full turn.

Front

How long does it take for the Earth to complete one rotation?

Back

It takes about one day (24 hours) for the Earth to complete one rotation.

Front

What causes day and night on Earth?

Back

Day and night are caused by the rotation of the Earth on its axis, as different parts of the Earth face the Sun and then move away from it.

Front

What is the difference between rotation and revolution?

Back

Rotation refers to the spinning of an object on its axis, while revolution refers to the movement of one object around another, such as the Earth revolving around the Sun.

Front

What is the axis of the Earth?

Back

The axis of the Earth is an imaginary line that runs from the North Pole to the South Pole, around which the Earth rotates.

Front

What is the effect of Earth's rotation on the Sun's position in the sky?

Back

As the Earth rotates, the position of the Sun appears to change in the sky, causing it to rise in the east and set in the west.

Front

What is a revolution in terms of Earth's movement?

Back

A revolution is the movement of the Earth around the Sun, which takes about 365 days to complete one full orbit.

Front

What is the significance of the Earth's rotation speed?

Back

The Earth's rotation speed affects the length of day and night, with one complete rotation taking approximately 24 hours.

Front

What happens at point B on Earth during sunset?

Back

At point B, the Sun is setting as the Earth rotates, causing that location to move out of the sunlight.

Front

What is the relationship between Earth's rotation and time zones?

Back

Earth's rotation leads to the creation of time zones, as different areas of the Earth experience daylight and darkness at different times.
