Inside Earth

Many scientists believe that crustal plate movements occurs because of convection cells contained in the Earth's 

• crust
• outter core 
• mantle 
• inner core

Movement of Earth's crust along plate boundaries produces

• earthquakes
• fronts
• tides
• hurricanes

The San Andreas Fault is the result of 

• Weathering and erosion
• hurricanes
• crustal plate movement
• orbital shape

Convection currents are located in the

• crust
• inner core
• outter core 
• mantle

Convection currents in the Earth's mantle are believed to be responsible for 

• rotation and revolution
• climatic changes 
• weather and climate
• crustal plate movements

Pangaea is 

• the name of the supercontinent
• a convergent boundary
• the name of an extinct ocean animal
• an edge of a continent

Earth's lithosphere is broken into separate sections called 

• rifts 
• plates
• boundaries
• rock

Subduction is 

• the direct transfer of heat
• the force that pushed and pulls the continents
• molten material
• the process of where oceanic crust sinks under trenches

What erupts through the valley of the mid-ocean ridge?

• continental crust
• molten material 
• layers of rock
• the lithosphere

Fossils of plants and animals in Antarctica are evidence for the theory of 

• sea-floor spreading
• subduction
• continental drift
• mountains
