They form over hotspots
They release pressure that has built up under Earth's crust
9
A seismologist sets up an experiment using a shake table. What is he trying to find?
the strength of an earthquake
when an earthquake is likely to occur

10
Which of the following statements about barrier islands and sand spits is true?

They help protect mainland areas from wave erosion.
They are hills made and shaped by the wind.
They form only where a river flows into the ocean
11
What happens to a bare hillside when it rains?
