Plate Tectonics

Front

Rocky or rigid outer part of Earth consisting of the brittle crust and the top part of the upper mantle

Back

Lithosphere

Front

Mantle convection is the very slow creeping motion of Earth’s solid silicate mantle caused by ________ carrying heat from the interior to the planet's surface.

Back

Convection Currents

Front

Solid, outer layer and is made of both the oceanic and continental crust.

Back

Crust

Front

Hot fluid or semi-fluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.

Back

Magma

Front

The thick part of the earth's crust that forms the large landmasses. It is generally older and more complex than the oceanic crust.

Back

Continental Crust

Front

What geological feature MOST often forms where two continental plates collide?

Back

Crustal plates that pull apart from one another MOST likely form

Back

rift zones

Front

Which two plates collided with each other to form the Himalayan Mountains?

Back

• a continental plate sliding past a continental plate
• an oceanic plate colliding into a continental plate

Back
