Plate Tectonics ES.7 b/c

Front

What is a strike-slip fault?

Back

A type of fault where two blocks of the Earth's crust slide past each other horizontally.

Front

What type of plate boundary involves plates moving towards each other?

Back

Convergent boundary.

Front

What is a divergent boundary?

Back

A plate boundary where two plates move away from each other.

Front

What is a transform boundary?

Back

A plate boundary where two plates slide past each other horizontally.

Front

What causes the movement of Earth's tectonic plates?

Back

Convection currents in the mantle.

Front

How do geologists study Earth's interior layers?

Back

By recording and studying seismic waves.

Front

What is subduction?

Back

The process where one tectonic plate moves under another plate and sinks into the mantle.

Front

What is continental drift?

Back

The theory that continents have moved over geological time and were once joined together.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The semi-fluid layer of the mantle beneath the lithosphere that allows for tectonic plate movement.
