Sun's Rotation and Shadows

Front

What is the term for the spinning movement of the Earth about its axis?

Back

Rotation

Front

What causes the sun to appear to move across the sky each day?

Back

The rotation of the Earth on its axis causes the sun to appear to move across the sky.

Front

How do shadows change throughout the day?

Back

Shadows change in length and direction as the position of the sun changes in the sky due to the Earth's rotation.

Front

At what time of day is a shadow typically the shortest?

Back

Noon, when the sun is at its highest point in the sky.

Front

What is the relationship between the position of the sun and the length of shadows?

Back

As the sun rises and sets, the length of shadows changes; they are longest in the morning and evening and shortest at noon.

Front

What factors influence the length of a shadow?

Back

The angle of the sun's rays and the height of the object casting the shadow influence its length.

Front

What is the significance of the Earth's tilt in relation to shadows?

Back

The tilt of the Earth affects the angle of sunlight and thus the length and direction of shadows throughout the year.

Front

How does the time of year affect the position of the sun in the sky?

Back

The Earth's axial tilt causes the sun to take different paths across the sky at different times of the year, affecting shadow length and direction.

Front

What is the term for the path the sun appears to take across the sky?

Back

Solar arc or solar path.

Front

Why do shadows point in different directions at different times of the day?

Back

Shadows point in different directions due to the changing position of the sun in the sky as the Earth rotates.
