Plate Tectonics

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

• Divergent Boundary
• Convergent Boundary
• Transform Boundary
• Subduction

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

• America
• Super Earth
• Pangea
• Eurasia

A Plate Boundary where two plates move toward each other is called

• Convergent Boundary
• Divergent Boundary
• Transform Boundary
• Subduction

Convergent Plate Movement can create

• Rifts
• Mountains
• Ocean Ridges
• Radiation

_______________ 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

Divergent Plate movement can create

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

When pressure builds between two tectonic plates, it can suddenly release causing a (an) ______________________

• Earthquake
• Volcano
• Convection Current
• Gravitational Pull

In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?

• The strong ocean currents are undermining both areas causing earthquakes.

• Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.

• Both areas are subjected to strong ocean wind and waves that causes earthquakes.

• Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.

Subduction zones occur on Earth where dense oceanic crust dives under more buoyant continental crust. These boundaries are characterized by a deep ocean trench next to a high continental mountain range, large numbers of earthquakes and volcanoes. All of this is further evidence for the

• big bang theory.
• theory of plate tectonics.
• origin of the species.
• theory of natural selection.
  

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

• convergent
• thrust
• divergent
• transform
