Introduction to Plate Tectonics

___________ is the theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle.

• Seismic waves

• Convection current

• Divergent boundary

• Plate tectonics

A _________ is a valley that forms where two plates move apart.

• Fissure

• Rift valley

• Sea-floor spreading

• Fault

​ (a)   the process by which rock material moves under Earth’s outer layer and into the mantle due to plate motion

• subduction

• uplift

• weathering

• sediment

Match the following

• Divergent boundary

• process in which two lithospheric plates of different densities converge and the denser one sinks into the mantle beneath the other

• Convergent boundary

• A plate boundary where two tectonic plates move apart from each other

• Transform boundary

• A plate boundary where two tectonic plates slide horizontally past one another

• Subduction

• A plate boundary where two tectonic plates move toward each other and collide

Match the following

• Continental crust

• Boundary where two tectonic plates meet

• Plate boundary

• thinner, more dense, located under oceans and seas, composed mostly of basalt, generally younger than continental crust

• Oceanic crust

• • thicker, less dense, forms landmasses, composed mostly of granite, generally older than oceanic crust

This image shows the formation of a mountain range at this ​ (a)   plate boundary.

• convergent

• destructive force

• force field

• divergent
