Shadows depend on the location of the light source.

If, for example, the sun is your light source it will change the size and shape of shadows as it crosses the sky during the day.

How and why do shadows change during the day?

Shadows change throughout the day due to the movement of the sun across the sky. In the morning and evening, when the sun is lower in the sky, shadows are longer because the sunlight has to travel through more of the Earth's atmosphere. At midday, when the sun is directly overhead, shadows are shorter as the sunlight hits objects more directly.


How does rotation cause shadows to change?

Rotation causes shadows to change in length and direction due to the shifting position of the light source, typically the sun. As an object rotates, the angle of sunlight hitting it changes throughout the day, leading to varying shadow lengths; for instance, shadows are longest during sunrise and sunset, and shortest at noon. Additionally, the orientation of the object relative to the light source alters the direction of the shadow, creating dynamic patterns over time.


Movement that causes shadows to change?

The movement of the sun across the sky during the day causes shadows to change. As the position of the sun changes, the angle and length of shadows cast by objects also change. This daily movement of the sun is responsible for the continuous shifting of shadows throughout the day.


What is the effect of time of day on shadows?

The position and length of shadows change throughout the day due to the angle of the sun in the sky. Shadows are longest and most defined closer to sunrise and sunset, when the sun is lower in the sky. At midday when the sun is directly overhead, shadows are shortest and may appear directly below the object casting them.


How do shadows change during a day?

Shadows occur when the Earth rotates and the position of the sun appears to change. Therefore, the position of the sun's rays hit the object at different angles causing a shadow to change shape.
