What Causes the ‘Tides’ and Why Do They Change Daily?

The moon pulls on the Earth like a giant magnet. When it's close, the water gets pulled up, making high tides. When it moves away, the water goes down, causing low tides. That’s why tides change every day, it’s like the ocean is breathing with the moon’s rhythm!

How It Works

The Earth and the Moon are always pulling on each other. The side of the Earth that faces the moon gets pulled more strongly, making high tide, while the opposite side also gets a little pull, causing another high tide too.

Every 12 hours or so, you get a new high or low tide, it’s like the ocean is doing a wave dance all day long!

Examples

  1. When you're at the beach during a high tide, it's because the moon is pulling on the water. High tide makes the water come up to your toes!
  2. Imagine the moon is like a giant magnet that pulls the ocean toward it. That’s why there are high tides when the moon is near and low tides when it’s far away.
  3. Your local beach might have two high tides every day, one in the morning and one in the evening. It's like the water is breathing with the moon.
