While the moon's gravity is weaker than Earth's, especially at Earth's distance from it, it still attracts Earth and everything on it, though not nearly as much as Earth's own gravity does. Lunar tides are not simply a result of the moon's, but rather because the strength of an object's gravity decreases with distance. This means that the side of Earth facing the moon is more strongly attracted to it than Earth's center is, which in turn is more strongly attracted than the far side is.

On the side of Earth facing the moon, the moon's gravity partially counteracts Earth's gravity, causing it to lessen slightly, allowing water levels to rise to form high tide. As Earth is pulled toward the moon, water on the far side of Earth, which is less attracted to the moon, lags behind slightly, forming a second high tide. This is why most areas experience two high tides and two low tides per day.

What makes tides occur?

Gravity(the pull that keeps us on earth)


Force that causes tides to occur on earth?

The gravitational force exerted by the moon and the sun on Earth's oceans causes tides to occur. The moon's gravitational pull is stronger than the sun's, resulting in two high tides and two low tides each day.


What forces causes the earth's highest tides in the ocean?

The earth's highest tides are caused by the gravitational pull of the moon and sun on the earth's oceans. When the sun, moon, and earth are aligned during a full moon or new moon, their gravitational forces combine to create higher tides known as spring tides.


Spring tides are unusually high and unusually low tides that occur when the moon earth and sun are all in line - during which moon phases do spring tides occur?

The sun and the moon's gravity pull in the same direction .


How does the phases of the moon affect the tides at sea?

the phases of the moon don't affect tides. Tides are caused by the moon's gravity, the moon is always at the same distance from Earth. Sun also causes the tides. so if the sun and the moon are directed in the same place at Earth extra high tides occur.


Are the tides on earth caused by the gravity?

Tides on Earth are caused by the gravity of the moon and, to a lesser degree, the sun.


Do tides occur at the same time?

No. Tides are generated by the combined gravity of the Sun and the Moon on the Earth's oceans. The Moon goes around the Earth each month, so the tides will vary both in time and in magnitude depending on the relative positions of the Earth, Sun and Moon.


How moon produce tides if there is no gravity on moon?

The moon does have gravity. Surface gravity on the moon is about 1/6 what it is on Earth.


What phenomena are the results of gravity between the moon and the earth?

Tides are the result of lunar (and solar) gravity.


What are Tides on Earth are causes by?

Tides on earth are mainly caused by the moon's gravity and earth's rotation.


How does the moon affect the earth's oceans?

The moons gravitational pull is what causes tides.


Why do tides occur on our planet explain?

a tide is when water levels change in a large body of water. tides occur because of the moons gravity. the position of the moon and how close it is to earth determines if it is a high tide or low tide.
