The Theory of Plate Tectonics

Name the boundary

• convergent boundary
• divergent boundary
• transform boundary
• sergent boundary

Name the boundary

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.

Scientists think that convection currents that move the plates flow in Earth's

• Continental crust
• Oceanic crust
• Asthenosphere
• Lithosphere

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

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

Which one occurs at transform boundaries?

• Volcanoes
• mountains
• trenches
• earthquakes

This land formation occurs at a divergent continental/ continental boundary.

• mid ocean ridge
• deep ocean trench
• pacific hot spot
• rift valley

Mountains form from ...

• plates sliding past one another
• collision of plates
• plates moving away from each other

Earth's plates are...

• constantly moving and changing the face of the earth
• Never moves
• Moves seldom and very fast
• Moves when it feels like it

The area around the pacific plate where boundaries form is called...

• death ring
• fire zone
• ring of fire
• zone of fire
