The motions of Earth relative to the Sun, and the motions of the Moon and Sun relative to Earth affect different phenomena on Earth, including day and night, the seasons, tides, and phases of the Moon.
The Eight Phases of the Moon
The Lunar Cycle is 29 days.
If the Moon is full on Day 1, it will be full again on Day 30.
Tides are the regular rising and falling of Earth’s surface water in response to the gravitational attraction of the Moon and Sun. The Moon’s gravity pulls upwards on Earth’s water, causing it to bulge out in the direction of the Moon. On the other side of the Earth, a high tide is produced where the Moon’s pull is weakest. The gravity of the Sun also pulls Earth’s water towards it and causes its own tides. Because the sun is so far away, its pull is smaller than the Moon’s.
During the summer, areas north of the equator experience longer days and shorter nights. In the Southern Hemisphere, the Sun is as far away as it will be and so it is their winter so these areas will have longer nights and shorter days.
The Earth's revolution (trip around the sun) takes 365 days!
