Plate Motion Chapter 2 Flashcard

Front

What is a plate boundary?

Back

The place where two plates meet; most volcanoes and earthquakes occur here.

Front

What is the outer layer of Earth made of?

Back

Hard, solid rock.

Front

What type of plate boundary occurs when two plates move towards each other?

Back

Convergent boundary.

Front

What is the definition of mantle?

Back

The layer of soft, solid rock underneath Earth's plates.

Front

What are the three main types of plate boundaries?

Back

Divergent, Convergent, and Transform boundaries.

Front

What happens at a divergent boundary?

Back

Plates move apart, creating new crust as magma rises to the surface.

Front

What geological features are commonly found at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs.

Front

What is the significance of transform boundaries?

Back

They are locations where plates slide past each other, often causing earthquakes.

Front

How does the movement of tectonic plates affect the Earth's surface?

Back

It can lead to the formation of mountains, earthquakes, and volcanic activity.

Front

What is subduction?

Back

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