What Causes ‘Tides’ and How Are They Predicted?

Imagine the ocean as a big bowl of water, and the moon is like a giant magnet in the sky. When the moon pulls on the water, it makes the ocean rise, that's a high tide! When the moon moves away, the water goes down, that's a low tide. The sun also helps pull the tides, but the moon has the strongest pull because it's closer to Earth.

Examples

  1. When you go to the beach during high tide, your foot gets wet up to your ankles, that's because the moon pulled the water toward it!
  2. Low tide is like when the ocean steps back and reveals hidden rocks or sandbars on the shore.
