5.8C Earth's Rotation

Front

What causes the Sun to appear to move across the sky?

Back

The Sun appears to move across the sky because Earth rotates on its axis.

Front

What causes day and night on Earth?

Back

Day and night on Earth are caused by the rotation of the Earth on its axis.

Front

How long does it take for one complete rotation of Earth?

Back

It takes about 24 hours for one complete rotation of Earth.

Front

What happens on a daily basis related to Earth's movement?

Back

The Earth rotates once on its axis every day.

Front

What is Earth's axis?

Back

Earth's axis is an imaginary line through the poles of Earth.

Front

What is the difference between rotation and revolution?

Back

Rotation is the spinning of Earth on its axis, while revolution is the movement of Earth around the Sun.

Front

What is the effect of Earth's rotation on time?

Back

Earth's rotation creates the cycle of day and night, which is divided into 24 hours.

Front

What would happen if Earth did not rotate?

Back

If Earth did not rotate, one side would always face the Sun (perpetual day) and the other side would be in constant darkness (perpetual night).

Front

What is the angle of Earth's axis?

Back

Earth's axis is tilted at an angle of approximately 23.5 degrees.

Front

How does the tilt of Earth's axis affect seasons?

Back

The tilt of Earth's axis causes different parts of Earth to receive varying amounts of sunlight throughout the year, leading to the seasons.
