Internal Forces Shaping the Earth

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

• earthquake

• tsunami

• volcano

• tectonic plate

Magma from the mantle rises as tectonic plates spread apart. The magma cools and forms new rock.

• Transform Boundary

• Convergent: Collision Boundary

• Convergent: Subduction Boundary

• Divergent Boundary

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

Plates slide past each other along a fault or fracture in the crust.

• Divergent

• Subduction

• Collision

• Transform

When two continental plates collide, neither one is subducted, and the plates buckle and fold.

• Transform

• Subduction

• Collision

• Divergent

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

True/False Earthquakes can cause tsunamis

• 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.
