What are tides?

Back

Tides are the rise and fall of sea levels caused by the gravitational forces exerted by the Moon and the Sun.

How does distance affect the pull of gravity?

Back

As the distance between two objects increases, the pull of gravity decreases.

Front

What is the effect of the Moon on tides?

Back

The Moon's gravitational pull causes the water in the oceans to bulge, creating high tides.
