Daytime Shadows. The animation below shows how shadows change during the day in the northern hemisphere. Shadows are created when an object, such as the stick below, blocks out some of the Sun's light. The length of the resulting shadow depends on how low or high the Sun is in the sky. read more
Shadows change length throughout the day because the angle at which the sun shines on stationary objects changes with the Earth’s rotation. For example, early in the morning, when the sun is near the horizon, it casts long shadows when an object blocks the light. read more
