unit 7 review plate tectonics

Front

What is Plate Tectonics?

Back

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

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with one another, causing geological activity.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other, often resulting in seafloor spreading.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, leading to the formation of mountains, earthquakes, and volcanic activity.

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 seafloor spreading?

Back

The process by which new oceanic crust is created at mid-ocean ridges as tectonic plates pull apart.

Front

What is a subduction zone?

Back

An area where one tectonic plate is being forced under another, often leading to volcanic activity and earthquakes.

Front

What causes tectonic plate movement?

Back

Convection currents in the mantle, which are caused by the heat from the Earth's core.

Front

What is the Ring of Fire?

Back

A major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to tectonic plate boundaries.

Front

What is an earthquake?

Back

A sudden shaking of the ground caused by the movement of tectonic plates.
