Earth's Rotation and Shadows

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 does Earth's rotation affect shadows?

Back

As the Earth rotates, the position of the sun changes in the sky, causing shadows to move and change in length.

Front

When are shadows longest during the day?

Back

Shadows are longest during the morning and evening when the sun is low in the sky.

Front

When are shadows shortest during the day?

Back

Shadows are shortest around noon when the sun is at its highest point in the sky.

Front

What causes a shadow?

Back

A shadow is created when an object blocks light from a light source, such as the sun.

Front

What is the position of the sun when shadows are longest?

Back

The sun is low in the sky during the morning and evening, which creates longer shadows.

Front

What is the position of the sun when shadows are shortest?

Back

The sun is directly overhead at noon, resulting in the shortest shadows.

Front

What happens to shadows as the sun rises?

Back

As the sun rises, shadows become shorter until they reach their shortest point at noon.

Front

What happens to shadows as the sun sets?

Back

As the sun sets, shadows become longer again until it gets dark.

Front

What is the effect of the sun's angle on shadow length?

Back

The angle of the sun affects shadow length; a lower angle creates longer shadows, while a higher angle creates shorter shadows.
