Theory of Plate Tectonics

Front

What is an Ocean-Ocean Convergent boundary?

Back

A type of plate boundary where two oceanic plates collide, leading to the formation of volcanic island arcs.

Front

What is the thinnest layer of the Earth?

Back

The crust.

Front

What causes the movement of tectonic plates?

Back

Convection currents in the Asthenosphere.

Front

What type of plate boundary occurs when two plates separate?

Back

Divergent Boundary.

Front

What is the tectonic stress that squeezes rocks together called?

Back

Compression.

Front

What is a Volcanic Island Arc?

Back

A chain of volcanic islands formed at an ocean-ocean convergent boundary.

Front

What is the Asthenosphere?

Back

A semi-fluid layer of the mantle that allows tectonic plates to move.

Front

What is a Rift Valley?

Back

A lowland region formed by the divergence of tectonic plates.

Front

What is a Transform Boundary?

Back

A type of plate boundary where two plates slide past each other.

Front

What is Tension in tectonics?

Back

A type of stress that pulls rocks apart.
