The Lithosphere and plate movement

The supercontinent in the continental drift hypothesis was called ____.

• Pantry
• Pangaea
• Wegenerland
• Eurasia

The lithospheric plates move an average of ____.

• 5 inches/year
• 5 cm/year
• 3 cm/year
• 5 feet/year

What kind of plate boundary occurs where two plates grind past each other without destroying or producing
lithosphere?

• convergent 
• transform
• divergent

The Himalayas in South Asia are an example of what type of plate boundary?

• continental-oceanic convergent
• continental-continental convergent
• oceanic-oceanic convergent
• continental-continental divergent

According to the theory of plate tectonics, ________.

• the asthenosphere is divided into plates
• the lithosphere is divided into plates

What forms when one oceanic plate is forced beneath another plate?

• subduction zone
• an ocean ridge
• a rift valley
• an ocean basin

Oceanic lithosphere is destroyed at ______

• transform fault boundaries
• divergent boundaries
• ocean ridges
• convergent boundaries

The convergence of two continental plates would produce ___________.

• island arcs
• rift valleys
• folded mountains
• trenches

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.
