Tidal Forces

The force that changes the levels of the oceans is known as tidal force.
The mutual force between Earth and the moon is gravitational force.
Gravitational force is responsible for much more than just the changing levels of the oceans.
Tidal force is the difference in the strength of gravity between two points on a body.

Effects of Tidal Forces

Tidal forces cause the oceans to flow into bulges on the side of the Earth facing the moon.
They also cause the oceans to bulge out on the opposite side of the Earth, away from the moon.
Tidal forces cause the levels of the oceans to rise and fall, resulting in tides.

Tidal Bulges

The deformation of a body stemming from tidal forces is called a tidal bulge.
Tidal bulges are less pronounced in the solid parts of the Earth compared to the oceans because the solid Earth is more rigid and resistant to deformation.

Tides on Earth

The sun also influences the oceans, along with the moon, and this combined effect causes the tides to rise and fall.
The alignment of the moon, sun, and Earth at full moon and new moon causes spring tides, resulting in higher high tides and lower low tides.
The misalignment of the moon, sun, and Earth at quarter moon causes neap tides, resulting in lower high tides and higher low tides.
The rotation of the Earth causes the tides to rise and fall twice in 24 hours.

Moon's Orbit

The moon's orbit is not a perfect circle, which causes the tides on Earth to be slightly ahead compared to prior images.
