Plate tectonics 7.2.5 test review

Front

What is plate tectonics?

Back

The theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often forming mountains or causing subduction.

Front

What is subduction?

Back

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

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other, often creating new oceanic crust.

Front

What is a rift valley?

Back

A lowland region formed by the divergence of tectonic plates, often associated with volcanic activity.

Front

What is an ocean ridge?

Back

An underwater mountain range formed by plate tectonics at a divergent boundary where new oceanic crust is created.

Front

What are folded mountains?

Back

Mountains that form when two continental plates collide and push the Earth's crust upwards.

Front

What is an ocean basin?

Back

The area of the ocean floor that is below sea level, often formed at divergent boundaries.

Front

What is a hot spot?

Back

A location on the Earth's surface that has experienced active volcanism for a long period, often not associated with plate boundaries.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is denser and thinner, while continental crust is thicker and less dense.
