Rotate and Revolve

Front

What is the definition of rotation in the context of Earth?

Back

Rotation refers to the spinning of the Earth on its axis, which takes approximately 24 hours to complete one full turn.

Front

What is the effect of Earth's rotation on day and night?

Back

Earth's rotation causes the cycle of day and night, as different parts of the Earth are exposed to sunlight or darkness.

Front

How does the speed of Earth's rotation affect the length of a day?

Back

If Earth rotated more slowly, the length of a day would increase, resulting in longer periods of daylight and darkness.

Front

What is the relationship between Earth's rotation and the apparent movement of the Sun across the sky?

Back

The apparent movement of the Sun across the sky is due to Earth's rotation, which makes it seem as though the Sun is moving from east to west.

Front

What causes the length of shadows during the day?

Back

The length of shadows is affected by the position of the Sun in the sky, which changes due to Earth's rotation.

Front

What is the difference between rotation and revolution?

Back

Rotation is the spinning of an object on its axis, while revolution is the movement of an object around another object in an orbit.

Front

How long does it take for Earth to complete one revolution around the Sun?

Back

It takes approximately 365.25 days for Earth to complete one full revolution around the Sun.

Front

What is the significance of the tilt of Earth's axis?

Back

The tilt of Earth's axis is responsible for the changing seasons as it affects the angle and intensity of sunlight received at different times of the year.

Front

What is the Coriolis effect and how is it related to Earth's rotation?

Back

The Coriolis effect is the deflection of moving objects (like air and water) due to Earth's rotation, influencing weather patterns and ocean currents.

Front

What is the role of gravity in the Earth's rotation?

Back

Gravity helps to keep the Earth in a stable rotation by pulling it towards the center, maintaining its shape and preventing it from flying apart.
