Review of Plate Tectonics

Where do volcanoes occur?

• divergent boundaries

• convergent boundaries

• ring of fire

• all of the above

Magma is

• liquid minerals
• liquid chemicals
• liquid rock
• the same as lava

A subduction zone is formed...

• when one tectonic plate sinks below another
• at every type of convergent plate boundary
• at every type of divergent plate boundary
• at transform boundaries

Which of the following did not support continental drift?

• location of volcanoes

• identical fossils on continents

• mountain ranges

• coastlines fit like a puzzle

Which of the following occurs because of convection currents?

• Tectonic plates on the crust move.
• The mantle increases in size.
• Pressure in the crust increases.
• Pressure in the crust decreases.

The physical layer of Earth made of solid rock and soil is called the ___________. 

• mesosphere
• lithosphere
• asthenosphere
• mantle

Where does the heat come from that drives this convection current in the mantle? 

• The sun
• The crust
• the mantle
• the core
