Erosion and rain cause it
Yes it does change, eventually the further away you go the lighter the shadow gets. And depending on if you move a couple of centimetres off, the shadow might start to contour!
Coal, to make steam.
The pH of soil will change as you move further away from a lake due to the increase of nutrients found in soil.
the dense canopy further away blocks light however where rivers are there is a gap in the canopy which lets light in so things can grow at lower levels.
The speed of light is constant, regardless of how far it is from its source.
Your shadow appears smaller when you are nearer to the light source and larger when you are further away. This is because the closer you are to the light source, the more direct and concentrated the light is, resulting in a sharper shadow with less dispersion. Conversely, the further away you are, the light is more spread out, causing your shadow to appear larger.

Doppler effect refers to the change in wavelength and frequency that occurs when an object moves towards or away from a source of waves.
Shadows change size based on the position of the light source relative to the object casting the shadow. When the light source is closer to the object, the shadow appears larger, and when the light source is further away, the shadow appears smaller. The angle of the light hitting the object also affects the size of the shadow.
Wind, rivers (water), glaciers, volcanoes, and earthquakes. They change by taking Earth bits away.
Doppler effect refers to the change in wavelength that occurs when an object moves toward or away from a source.
Your shadow will become longer and less defined as you move away from the light source. If you move further away, your shadow may eventually disappear completely depending on the distance from the light source.
