Hot liquid rock found INSIDE of Earth is called

• lava
• sediment
• magma
• cement

A type of rock that forms when heat and pressure change an existing rock to another type of rock (the rock does not melt) is called

• sedimentary rock
• metamorphic rock
• igneous rock

A kind of igneous rock that cools very quickly out on the surface of Earth is described as

• sedimentary
• intrusive
• metamorphic
• extrusive

During the process of compaction, layers of sediments are pressed together by

• animals walking on the surface of the ground.
• the weight of the sedimentary layers above them.
• the freezing of water and melting of ice.
• roots pushing through the sediments.

The red arrow shows Earth's crust and upper mantle where solid rocks are found. This area is called the

• oceanic basin
• lithosphere
• crustal sphere
• hydrosphere

Tectonic plates can move rocks very deep into Earth. What happens to the temperature and pressure as you move deeper into Earth?

• the temperature gets hotter and there is less pressure
• the temperature gets colder and there is less pressure
• the temperature gets hotter and there is more pressure

Which of the types of rock can go through the process of weathering and erosion to form sediment?

• Only sedimentary rock can go through the process of weathing to become sediment
• Only igneous and metamorphic rock can go through the process of weathering to become sediment
• Any sedimentary, igneous, and metamorphic rock can go through the process of weathering to become sediment

A friend brings you a rock to identify. The rock is dark gray with tiny crystals. The rock has air bubbles on its surface. The rock is best identified as

• an igneous rock that cooled slowly deep inside Earth
• a metamorphic rock that formed from sandstone
• an igneous rock that cooled very quickly
• a sedimentary rock full of fossils
