Investigate Tides

The sea level rises and falls every day. These changes are called tides. Tides happen because of the gravitational pull of the Moon and the Sun on Earth's oceans. The Moon has the strongest effect because it is much closer to Earth. 

Explore Tides

The ocean’s tides rise and fall every day, but have you ever wondered what causes them? The Moon and Sun both play a role in shaping the movement of water across the Earth.

The Moon is the largest and brightest object we see in the night sky.
