What causes tides in the sea?

               we have all seen tides near sea, but do you know what causes tides to happen.

let's see what causes tides.

Tides are the periodic rise and fall of the sea level at a particular place.
when the sea level is rises to its greatest height, it is known as a high tide and when the sea level drops to it lowest height, it is known as low tide.

Tides are primarily caused due to the gravitationally force of the moon.
part of the earth facing the moon experiences a stronger gravitational pull toward the moon as compare to the earth's center.

so, the part facing the moon is pulled away from the center, creating a bulge.
thus, increasing the sea level and causing a high tide.

now, the earth's center experiences a strong gravitational force towards the moon than the part facing away from the moon.
hence, this part is pulled away from the center, resulting in high tide on the opposite side aswell.

in addition to this, the place between the two high tides, where the sea level drops,
experience low tides.
