What causes tides and how do they affect coastal areas?

Tides are like the ocean breathing in and out because of the moon and sometimes the sun.

Imagine you're playing with a bucket of water and a toy boat. When you pull the bucket toward you, the water moves forward, pushing your boat. That’s like what happens when the moon pulls on Earth's oceans, it makes them rise up in some places, creating a high tide. Then, when the moon moves on, the water goes back, making a low tide.

The moon is like a giant magnet that gently tugs on Earth’s oceans. Even though it's far away, its pull is strong enough to make the ocean move. When the moon, sun, and Earth all line up, their pulls add up, creating really big tides, these are called spring tides.

Coastal areas feel the effects of tides every day. Beaches get covered with water during high tides and then exposed when the tide goes out. This can change how people play on the beach, or even affect where boats can dock. Sometimes, strong tides can cause floods in low-lying coastal towns, like when the ocean comes in really far.

Tides are a big part of life near the sea, they're like the ocean’s regular rhythm!
