• Rift
• Island Arc

A subduction zone is formed...

• when one tectonic plate sinks below another

• at every type of divergent plate boundary
• at transform boundaries

Plates slide past one another at ____________ boundaries.

• divergent

• transform
• submergent

What kind of plate boundary is shown here?

• divergent
• convergent
• transform

Plate movement is caused by ______________.

• the rotation of the Earth
• ocean tides
• convection currents in the mantle
• the moon's gravity

The crust and the uppermost mantle make up the ________________.

• lithosphere
• asthenosphere
• atmosphere
• hydrosphere

Earthquakes typically occur _________________.

• In the middle of tectonic plates
• only in California
• only in the middle of the ocean
• along plate boundaries

The plastic-like layer that is located directly under the lithosphere is known as the ____________.

• lithosphere

• atmosphere
• photosphere

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.

Oceanic plates separate from each other at a divergent plate boundary at the bottom of the ocean.  Magma comes up and cools between the plates, forming...
