Plate Tectonics Part 1

Front

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

Back

Lithosphere

Front

What causes the slow creeping motion of Earth’s solid silicate mantle?

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

In the region where two continental plates collide, what geological feature MOST often forms?

Back

a mountain chain

Front

Crustal plates that pull apart from one another MOST likely form

Back

rift zones

Front

The lithosphere can be ___ at plate boundaries.

Back

All of these

Front

Which of these tectonic plate boundaries is most likely to form a volcano? a continental plate colliding with a continental plate, an oceanic plate sliding past a continental plate, a continental plate sliding past a continental plate, an oceanic plate colliding into a continental plate

Back

an oceanic plate colliding into a continental plate

Front

What causes the tectonic plates to continually move?

Back

Convection currents
