Plate Tectonic Theory

Multiple Choice

Scientists hypothesize that a super continent existed 200 million years ago.  This continent is called

• America
• Super Earth
• Pangea
• Eurasia

Multiple Choice

_______________ Currents within the mantle cause the earth's plates to move and shift s molten material rises and falls due to density and gravity

• Convection
• Radiation
• Conduction
• Wind

Multiple Choice

A plate boundary where two plates move away from each other is called

• Divergent Boundary
• Convergent Boundary
• Transform Boundary
• Subduction

Multiple Choice

Divergent Plate movement can create

• Convection Currents
• Conduction
• Mountains
• Rifts and ocean ridges

Multiple Choice

There are three types of plate boundaries. Which choice is NOT a type of plate boundary?

• convergent
• thrust
• divergent
• transform

Multiple Choice

Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

• the oceanic crust is melting.

• the denser oceanic crust is subducting under the less dense continental crust

• volcanic islands are forming.

• the tectonic plates are moving away from each other.

Multiple Choice

The map in the picture shows tectonic plate boundaries. This map would be useful in predicting the location of future

• droughts

• hurricanes

• earthquakes

• tornadoes

Multiple Choice

What geological forces might be responsible for this range of mountains?

• diverging tectonic plates
• erosion of the land by the ocean
• converging tectonic plates
• deposition of sediments by the ocean
  

Multiple Choice

The Earth’s surface is not a solid surface but is divided into

• several oceanic plates.
• continental and crustal plates.
  
• seven continental plates.
• continental and oceanic plates.
  

Multiple Choice

Where are earthquakes MOST LIKELY to occur?

• close to the equator

• close to the center of tectonic plates

• at divergent or convergent plate boundaries

• at transform plate boundaries

Multiple Choice

Which crust subducts because it is denser than other crust?

• pizza crust

• oceanic crust

• continental crust

• new crust

Multiple Choice

What type of plate boundary creates new sea floor?

• Divergent

• Convergent

• Transform

• Subduction

Multiple Choice

Convergent Plate Movement can create
