How the Moon Causes Tides on Earth

Описание: The Moon controls Earth’s tides mainly through gravity. Here’s a simple, clear explanation:


🌙 How the Moon Causes Tides on Earth

1. Moon’s gravity pulls on Earth’s water

The side of Earth facing the Moon feels a stronger pull.

This causes the water to bulge outward → high tide.



2. Opposite side also gets a high tide

On the side away from the Moon, gravity is slightly weaker.

Water lags behind, forming another bulge → high tide.



3. Two high tides & two low tides every day

As Earth rotates, different areas pass through these bulges.

Places moving into the bulge get high tide, and moving out get low tide.




🌍 Sun also helps, but Moon is stronger

The Sun’s gravity also affects tides, but the Moon is closer, so its effect is much stronger.


🌊 Types of tides

Spring tides: Strongest tides when Sun, Moon, and Earth are in a straight line (Full Moon & New Moon).

Neap tides: Weakest tides when Sun and Moon form a 90° angle (First & Last Quarter Moon).


If you want, I can also give a diagram-style explanation.
