Because the sun moves across the sky (the world spins around it)
The earth rotates around the sun causing different shadow lengths
Because the sun seems to move.
Yes. The shadows vary with how high above the horizon the Sun is. Close to the horizon = long shadows. Straight above = short shadow. Your powers of observation will show you that they do. Continuously.
Shadows are caused by the sun's rays upon the earth. As the sun rotates and moves during the day, the rays move and so shadows also move during daytime
It gets shorter. At mid day it reaches its shortest point, and throughout the rest of the day grows longer. Also, it drifts from west to east. In the northern hemisphere, it points generally north at mid day, swiveling around to the east in the afternoon.
it means that the shadows at noon are small.
"how much does humidity change in a day?"
the shadows change as the earth rotates on its axis. the sun stays still so the shadows change.
we don't now
when you move and when the sun angle changes
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.
when you move and when the sun angle changes
shadow will become short when it was xiawu and no shadow at night! haha At noon, when the sun aerial, and shadows is the shortest. When the sun goes down, the shadows change into the longest.
The earth tilt toward the sun
the lengths and direction of shadows change during the day because of some factors these are: 1) position of the earth facing the sun 2) time of the day 3) power of suns rays 4) place object is in 5) what object is around
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.
Yes. The shadows vary with how high above the horizon the Sun is. Close to the horizon = long shadows. Straight above = short shadow. Your powers of observation will show you that they do. Continuously.
afternoon
The angle of the earth to the sun changes the direction and size of shadows during the day. Since the earth rotates giving us night and day, the angle at which the suns light is hitting the earth(and you) determine the size/shape of the shadow
