Revolution · Revolution is Earth traveling all the way around the Sun. One revolution takes about 365 days.
Rotation · Rotation is Earth spinning on its axis. One rotation takes about 24 hours.
درست · As Earth rotates, the side facing the Sun has daylight and the side facing away has night.
Waning · Waning means the Moon's lit part is getting smaller each night.
Waxing · When the Moon's lit part grows night after night, that is called waxing.
A solstice · A solstice is the day with the longest or shortest daylight of the year.
He has it backwards: rotation causes day and night, revolution (with Earth's tilt) causes seasons · Rotation, Earth spinning on its axis, causes day and night. Revolution, along with Earth's tilt, causes the seasons over the year.
Earth's tilted axis makes sunlight hit the two hemispheres differently as Earth revolves · Earth's axis stays tilted the same way as it revolves, so each hemisphere gets more or less direct sunlight depending on the time of year.
