Plate Tectonics Final

Front

At which plate boundary is new crust formed?

Back

Divergent boundaries are where new crust is formed as tectonic plates move apart.

Front

The majority of the world's earthquakes and volcanoes occur along the _ .

Back

The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.

Front

What is a driving force behind the movement of the plates?

Back

Convection currents in the mantle are a driving force behind the movement of tectonic plates.

Front

At which boundary is crust neither consumed nor created?

Back

Transform boundaries are where crust is neither consumed nor created as tectonic plates slide past each other.

Front

The earth's outer shell is divided into slabs of rock called ______ .

Back

Tectonic plates are the slabs of rock that make up the Earth's outer shell.

Front

What are tectonic plates?

Back

Tectonic plates are large, rigid pieces of the Earth's lithosphere that move and interact with each other.

Front

What happens at a convergent boundary?

Back

At convergent boundaries, tectonic plates move towards each other, often causing one plate to be forced beneath another.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another and is forced into the mantle.

Front

What geological features are formed at divergent boundaries?

Back

Divergent boundaries can create mid-ocean ridges and rift valleys.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper mantle.
