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

24 hours.

Front

At what times of the day are shadows the longest?

Back

Shadows are longest in the early morning and late afternoon (around 7 AM and 6 PM).

Front

What happens to the position of the sun during Earth's rotation?

Back

The sun appears to move across the sky from east to west due to Earth's rotation.

Front

What is the axis of the Earth?

Back

The axis 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 day and night?

Back

Earth's rotation causes day and night; as the Earth spins, different parts face the sun (day) or move away from it (night).

Front

What is a day-night cycle?

Back

A day-night cycle is the period of time it takes for one complete rotation of the Earth, resulting in one day (approximately 24 hours).

Front

How can you demonstrate Earth's rotation using a model?

Back

You can demonstrate Earth's rotation by rotating a model (like an orange) around a fixed point (like a wooden rod) to show how Earth spins on its axis.

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 day and night at different times.

Front

What is the significance of noon in relation to Earth's rotation?

Back

Noon is the time when the sun is at its highest point in the sky for a specific location, marking the middle of the day.
