Amplify Plate Motion - Chapter 2

Front

What is Earth's outer layer made of?

Back

Earth's outer layer is made up of hard, solid rock.

Front

What type of boundary is formed when tectonic plates move towards each other?

Back

Convergent boundary.

Front

What happens at a convergent plate boundary?

Back

Plates collide, which can cause mountains to form or earthquakes.

Front

What is a divergent plate boundary?

Back

A boundary where tectonic plates move away from each other.

Front

What fills the gap created by plates moving apart?

Back

Soft, solid rock from underneath the plates rises and hardens, adding new solid rock.

Front

What is the composition of Earth's outer layer beneath soil and water?

Back

Underneath both the soil and the ocean, Earth’s outer layer is made of hard, solid rock.

Front

What is the significance of tectonic plate movement?

Back

Tectonic plate movement shapes the Earth's surface, causing earthquakes, volcanic activity, and the formation of mountains.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are thinner and denser, while continental plates are thicker and less dense.

Front

What is subduction?

Back

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

Front

What geological features can form at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs.
