Front

What is insolation?

Back

Insolation refers to the amount of solar radiation received by a given area, typically measured in watts per square meter.

How does the angle of the Sun's rays affect shadow length?

Back

As the angle of the Sun's rays decreases (from 90° to lower angles), the length of shadows increases.

Back

Insolation varies with latitude; areas near the equator receive more direct sunlight than those near the poles.

Front

What happens to the Sun's position in the sky during winter?

Back

During winter, the Sun's position in the sky is lower, resulting in shorter days and less intense sunlight.
