What causes tides in the ocean?

Tides are caused by the gravitational pull of the moon and the sun on Earth's oceans.

How do the positions of the moon and sun affect tides?

When the moon is directly overhead, its gravity pulls the water towards it, creating a high tide. The sun also affects tides, but to a lesser extent.

Are there different types of tides?

Yes, there are two main types of tides: spring tides, which occur during full and new moons, and neap tides, which occur during the first and third quarters of the moon.

How often do tides change?

Tides typically change every 6 hours, resulting in two high tides and two low tides each day.
