Plate Tectonics Vocab

The soft layer of the mantle on which the lithosphere floats

• Crust

• Mantle

• Mesosphere

• Asthenosphere

The rigid outer part of the earth, consisting of the crust and upper mantle

• lithosphere

• asthenosphere

• mesosphere

• round sphere

The theory that the crust is divided into large pieces called tectonic plates that slowly move on top of the mantle

• seafloor spreading

• continental drift

• tectonic plate

• plate tectonics

Huge piece of crust that slowly moves on the upper, ductile (able to be molded, like plastic) part of the mantle

• pangea

• continental drift

Match the following

• Plate boundary

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

• Continental crust

• Boundary where two tectonic plates meet

• Oceanic crust

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

Match the following

• Continental rifting

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

• Subduction

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

• Divergent boundary

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

• Convergent boundary

• The process by which a continent is pulled apart at a divergent plate boundary

• Transform boundary

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