Mini-Quiz: Gravitation Causes Tides on Earth

by Ron Kurtus

Take this Mini-Quiz to check your understanding of the lesson material.

1. Why does a high tide seem to go further up the shore in some places?

Those places are closer to the Moon

It is an optical illusion

It depends on the inclination of the shoreline

2. What happens when the Moon's gravitation pulls on the ocean?

It causes bulges in the shape of the ocean on both sides of the Earth

It pushes the Earth away from the water

Nothing, unless the Sun is also involved

3. When do spring tides occur?

Only in the spring

Every two weeks

Twice a day

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Sometimes you have to go with the flow
