A teacher squeezes a tube of toothpaste as a model of Earth's magma. The teacher is MOST likely showing —

Students placed several rocks in a

metal can. They each shook the

can for 15 seconds. When they

removed the lid, they noticed a

rocky soil had started to form.

What process created this soil?

• melting

• evaporation

• heating

• weathering

If an earthquake happens in the ocean, then it could rapidly change land on

Earth by causing —

• a thunderstorm that floods the shores and washes them away.

• colder waters that make it snow over low lands causing them to freeze.

• a huge wave that floods the land and pulls some of it away.

• warmer waters that make it rain over mountains and cause landslides.

Mt. Vesuvius erupted over one thousand years ago. Many people and animals were buried by ash and "frozen" in place by this eruption. What does this show us?

• People and animals move slowly over a long period of time.

• Volcanoes can change the landscape of an area slowly.

• Volcanoes can change the landscape of an area quickly.
