Internal Forces that Shape the Earth

An enormous moving piece of the earth's lithosphere is a

• earthquake

• tsunami

• volcano

• tectonic plate

As plates push together, one plate is forces under the other. As the bottom plate starts to melt, magma rises and forms volcanoes at the surface.

• Divergent

• Subduction

• Collision

• Transform

A fracture in earth's crust is a

• tsunami

• fault

• Ring of Fire

• epicenter

Where are most volcanoes found?

• Asia

• Australia

• near the center of tectonic plates

• near plate boundaries

The difference between magma and lava is that lava is under the surface of the earth and magma is above the surface of the earth.

• True

• False

The Ring of Fire is

• a zone around the Pacific Ocean.

• a zone around the Atlantic Ocean.

• caused by tsunamis.

• part of the Richter scale.
