What Causes the ‘Tides’ and Why Are They Predictable?

The tides are like a big ocean stretchy band that gets pulled by the Moon and Sun. When the Moon is near, it pulls the water up on one side of Earth, making high tide there, and low tide on the other side. The Sun helps too, sometimes adding to the pull or even subtracting from it. Because this happens in a regular pattern, we can predict when tides will be high or low.

Examples

  1. Imagine the Moon is a giant magnet that pulls water from the ocean toward it, creating high tide on one side and low tide on the other.
  2. When you're at the beach during spring tides, the waves are much bigger than usual, like when both parents come to help you move furniture.
  3. If the Sun is far away, it's like a small friend who can't pull as hard as your best friend (the Moon).
