The tides are a gravitational effect. The Moon and the Earth pull on each other, so each elongates slightly in the direction of the other body. The effect is actually more pronounced for the Moon, because it is smaller. On the Earth, the gravitational pull results in more movement of water than of land, because the oceans lack the structural integrity of the Earth's crust to resist this pull. As a result, the seas form the tides in response to the Earth's rotation, as different portions of the Earth's surface elongate towards the Moon.
The Sun also causes tides. However, tides are not proportional to gravity, but to its gradient. As a result, the Sun causes tides only half as strong as those of the Moon. Still, the "spring tide" occurs when the Sun and Moon are on the same or opposite sides of the Earth, and is much stronger than the "neap tide" that occurs when the Sun and Moon form a right angle to the Earth.

The Moon exerts a non-uniform gravitational field in the course of the Earth's diameter. The "typical pressure" of this makes Earth wobble around the Earth-Moon barycenter. the version between that typical and the close by pressure on both part is what squishes and squashes on the earth as an finished. the sea is the most squishy area of the Earth's floor, so it reviews the tidal bulge maximum severe. replace the area of any oceanic area relative to the moon, and also you adjust its volume of bulge. because of this the tides progression on their cycles. both a moon above and a moon straight away opposite of above reason the acute of the day...it really is why there are 2 extreme tides an afternoon. A horizon moon makes the least severe tide of the day...subsequently 2 low tides in line with day. The solar to a lesser volume also impacts the tides, about 1/2 as a lot because the Moon. Proximity wins mass contained in the game of tides. The alignment or competition of the solar and moon makes for the most severe tides. We call those spring tides. The perpendicularity of the solar and moon makes for the genuine looking tides. We call those neep tides. do not anticipate tides to precisely tournament the causation nodes of the solar and moon. the reason being, is that the large ocean has an inertial lag of reaction to the causation nodes of the celestial bodies of stunning tidal impact.

The moon's gravitational pull causes the sea to bulge out towards it, which causes the tidal effect.
The sun's gravity also has the same effect to a lesser extent (it being further away). When the sun and moon are lined up you get extra high tides as they are pulling together, when they are at a right angle to each other you get an extra low tide as the gravitational forces are working against each other.

the moon can control the tides cause the at night time it is cold and when the moon is there than you would see the tides or currents go up. the moon has coldness that makes the wind blow and make the tides

the moon has a gravitational pull. As it orbits around the Earth, it pulls on the ocean water. This causes the oceans to rise and fall depending on the location of the moon.

Through its gravitational pull. When its orbit brings it closer to the earth we get higher tides. Some folk say this "pull" can affect human behaviour - hence words like "lunatic" and "moonstruck"

the gravity of the moon distorts the shape of the earth, causing water to rise and fall

Simply the strong gravitational pull it exerts over the oceans.
