the moon
The moon orbiting the earth is the main factor that produces the tides.
in the night whe have two tides in total is 4 two low tides in the day and two high tides in the night
The two main restoring forces for tides are gravitational forces from the Moon and the Sun. These forces create bulges in the Earth's oceans, causing high and low tides as the Earth rotates within this gravitational field.
there are 4 tides a day, 2 high, 2 low.
The main effect is the tides, Without the Moon's gravity the tides would be about one quarter as high as they are now, they would be the same every day, and there would be no spring tides or neap tides.
