What Is the Point of Tides?

The tides are like the ocean breathing in and out, it’s how the water moves up and down the shore because of something big happening far away.

Imagine you're playing with a toy boat in a bathtub. When you pull the plug, water rushes out, and your boat goes with it. Now imagine there's a giant invisible hand pulling on the bathwater from outside the tub, that’s kind of what happens with tides.

The Moon's Big Pull

The moon is like that giant invisible hand. It pulls on Earth’s oceans, making them rise up, and then fall back down again, just like your boat in the bathtub. This pulling causes the water to move: when it gets pulled toward the moon, we see a high tide, and when it moves away, we get a low tide.

Sometimes Two Pulls

Sometimes the sun also helps pull on the ocean, like having two giant invisible hands working together! When both the sun and moon are pulling in the same direction, the tides get even higher. That’s called a spring tide, and it's like getting double the fun at the beach.

When they’re pulling in different directions, the tides are a little calmer, that’s called a neap tide. It’s like when you're playing with your boat and someone else is trying to pull it in another direction.
