Plate Tectonics Quiz

Subduction plate boundaries around the Ring of Fire occur where

• Continental plates run into each other
• The sea floor is spreading
• Denser ocean crust goes under continental crust
• Fault lines are building potential energy 

What name is given to the type of crust that is primarily made up of basalt and is found at the bottom of the oceans?

• Divergent Crust

• Lithospheric Crust

• Oceanic Crust

• Continental Crust

Like a slow-motion collision, convergent plates result in

• The destruction of landforms
• An intense crashing sound
• The creation of mountain ranges such as the Rockies
• Higher insurance deductibles

What type of event will occur at this boundary?

• Earthquake
• Volcano Eruption
• Tornado
• Mountain Building

Like the spreading sea floor of the Atlantic Ocean,  Africa's Great Rift Valley is caused by

• Convergent plates
• Frequent earthquakes
• Divergent plates
• A tsunami

A convection current causes a swirling or circular motion.

• True

• False

200-300 million years ago, the continents were joined in a single land mass called...

• Pan America
• Pangaea
• Pan Acean
• 'Murica

What happens at a convergent boundary between tectonic plates?

• The plates move away from each other

• The plates slide past each other

• The plates move towards each other

• The plates remain stationary

Why do tectonic plates move?

• Due to the rotation of the Earth

• Because of gravitational pull from the moon

• Due to convection currents in the mantle

• Because of the expansion of the ocean

When two continental plates collide it creates....

• rift valleys

• mountains

• deep sea trenches

• forests
