The Moon is tidally locked in its orbit around the Earth. This occurs because one
side of the Moon is heavier than the other, and that side is the side facing the
Earth. For more information, please see the Related Link below.
Here is a simple activity that can help explain what we see:
-- Go outside in the yard with a friend.
-- You will be the Earth. You stand still, while your friend circles around you,
maybe 20 feet away from you. He will circle around you two times.
-- First, have your friend circle around you while he keeps facing the same direction ...
perhaps facing a house in the distance. Notice that as he makes one complete circle
around you, you can see every side of him one time.
-- Now for the second circle. Have him circle around you and only let you see the front of him.
Notice that in order to do that, he must rotate his body once, in the same time it takes him
to circle around you once.
Each year, the planet moves one full rotation around the sun, a movement. Each day, the planet revolves once, that's why in the day there is light because you are facing the sun, but when the earth revolves some more it is facing away from the sun eliminating the sun's light.
They aren't different, by earth standards. Luna is tidally locked to the earth's gravitation, so it always keeps the same side facing earth.
When the earth moves, the sun is left behind, so half of the earth is not facing the sun. Dumbo
Rotation is the term meaning turning a body part on its own axis.I find turning a body part on its own axis hard to explain. I can only give examples:Rotating your outstretched arm at the elbow or shoulder, say from palm up to palm down.Moving your head from facing front to facing left or right.
revolution around the Earth. This results in the same side of the moon always facing towards the Earth due to tidal locking.
A revolution is when you move 360 degrees or start facing in one direction and turn completely around until you reach where you started or 720 degrees. Basically turning until your facing the same place you started. A rotation is when you turn any number of degrees like 900 or 180. It could be a revolution. A rotation can be a revolution but not always is but all revolutions are rotations.
The Moon always keeps the same side facing Earth so its rotation period is the same as its period of revolution around the Earth. These periods are both about 27.3 Earth days.
yes... Its frequency of revolution equals its frequency of rotation.
Day and night are caused by the Earth's rotation on its axis. As the Earth spins, different parts are either facing towards the sun (daytime) or away from it (nighttime), creating the cycle of day and night.

Night and day are caused by the rotation of the Earth on its axis. As the Earth rotates, different parts of the planet are either facing towards the Sun (daytime) or away from the Sun (nighttime). This rotation takes approximately 24 hours to complete, resulting in the cycle of day and night.

The motion of a planet on its axis is called rotation. This rotation causes day and night cycles on the planet as different parts are facing towards or away from the sun.
