Earth Features

Molten rock is called magma. The illustration below shows how magma can rise to Earth’s surface.  As it cools, magma turns into solid rock on the surface. 

What type of rock does magma form as it cools?

• fossil

• igneous

• metamorphic

• sedimentary

Dr. Jones is searching for igneous rocks to add to her collection. She is interested in rocks that have recently been formed. Where can this type of rock most likely be found?

• near a volcano

• in a deep cave

• on a sandy beach

• at the mouth of a river

Tamika creates a display for her science project on metamorphic rocks.  She draws this diagram to show how metamorphic rock is formed.

Tamika’s Display

• Heat and pressure from the magma

• Transportation and heat in the layers below the rock

• Pressure and weathering in the layers above the rock

• Pressure from the above rock layers and heat from the magma

Gerardo is working to landscape his backyard.  To change the slope of his yard, he puts a large pile of dirt on the side of a hill and covers it with a large tarp.  Why should the dirt be covered?

• to create a level place for building on

• to help the dirt to settle into a solid mass

• to protect the dirt from freezing temperatures

• to prevent rain from carrying the dirt down the hill
