Sam is not sure what the difference is between the inner core and the outer core. Read each word or phrase that describes the inner or outer core of Earth, and then use the graphic organizer to place each word or phrase in the correct column. INNER CORE: choose all that apply

• solid

• liquid

• hottest layer

• under the most pressure

• causes the magnetic field

A student is watching a video in order to understand how convection in the mantle of Earth occurs. The video shows rock rising and sinking to make convection currents in the mantle. Which process is responsible for causing rock to rise?

• Rock is heated

• Rock rapidly cools off

• Rock increases in density.

• Rock undergoes intense pressure.

6. True or false. Rocks always follow the same path in the Rock Cycle.

• True

• False

Choose the answer that correctly completes the sentence for each part.

The cementing of small pieces of rock or shell causes (metamorphic / igneous / sedimentary / magma) rock to form. When rocks are buried below the surface, pressure combined with heat causes (metamorphic / igneous / magma / sedimentary) rock to

• Metamorphic, metamorphic

• Igneous, magma

• Sedimentary, metamorphic

• Magma, sedimentary

Evan examines a diagram of the rock cycle in his science textbook. He wonders how he can connect what he has learned about matter and energy to the rock cycle. Which statement best explains what happens to material as it moves through the stages of the rock cycle?

• New matter is being created all of the time.

• The same matter is recycled over and over.

• Eventually the broken-down matter disappears.

• Old matter is destroyed and new matter takes its place.

Some students are learning about the layers of Earth and are comparing the asthenosphere and the lithosphere. Choose two for lithosphere (crust).

• contains flexible rock

• under intense pressure

• includes the top layer of the ocean

• contains rock that is solid and hard
