Plate Tectonics Unit Review

What is Plate Tectonics?

Back

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

Front

What are the three main types of plate boundaries?

Back

1. Convergent boundaries: where plates move towards each other. 2. Divergent boundaries: where plates move apart. 3. Transform boundaries: where plates slide past each other.

Front

What is a Convergent Boundary?

Back

A tectonic plate boundary where two plates collide, often causing one plate to be forced beneath the other, leading to mountain formation or volcanic activity.

Front

What is a Divergent Boundary?

Back

A tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What is a Transform Boundary?

Back

A tectonic plate boundary where two plates slide past each other horizontally, often causing earthquakes.

Front

What is Weathering?

Back

The process of breaking down rocks and minerals through physical, chemical, or biological means.

Front

What is Erosion?

Back

The process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is Deposition?

Back

The process in which sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What causes Earthquakes?

Back

Earthquakes are caused by the sudden release of energy in the Earth's crust, often due to the movement of tectonic plates along faults.

Front

What is a Fault?

Back

A fracture or zone of fractures between two blocks of rock, which can cause earthquakes when the blocks move.
