Because of the Earth's rotation?
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.
the shadows change as the earth rotates on its axis. the sun stays still so the shadows change.
Shadows change when the sun moves in the sky because it hits objects from different directions, which causes them to cast a different shadow.

Shadows change length throughout the year because the altitude of the Sun above the horizon changes. The altitude (height above the horizon) of the Sun changes as the Earth revolves around the Sun each year. This is due to Earth's axis being at an angle. In the Northern Hemisphere, the North Pole is pointing away from the Sun on the winter solstice (around Dec. 21) and for the Northern Hemisphere the Sun is at its lowest altitude and shadows will be the longest of the year. On summer solstice (June 21), the Sun is at its highest altitude and shadows are the shortest of the year. Janice VanCleave
