Solution
The primary cause of tides on Earth is bthe moon.
Here's a step-by-step explanation:
-
The gravitational pull of the moon causes the water in the oceans to bulge out in the direction of the moon. This is what causes high tide.
-
On the other side of the Earth, there is another high tide. This is because the Earth itself is also being pulled toward the moon, but the water on the far side is being left behind.
-
As the Earth rotates, the areas of high tide travel around the planet. This is why most places see two high tides and two low tides every day.
-
The sun also has an effect on tides, but it is less than half as strong as the moon's effect. This is because, even though the sun is much more massive, it is also much farther away.
-
The Earth's rotation on its axis, its revolution around the sun, and its position relative to other planets can all have minor effects on tides, but the primary cause is the gravitational pull of the moon.
