Amplify Plate Motion Final Test

Front

What is the Earth's outer layer made of?

Back

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

Front

What happens when tectonic plates move toward each other?

Back

When tectonic plates move toward each other, one plate may go underneath the other, causing geological activity such as earthquakes.

Front

What is the significance of fossil remains found on different continents?

Back

Fossil remains found on different continents can indicate that those continents were once connected and have since drifted apart due to plate tectonics.

Front

What is plate tectonics?

Back

Plate tectonics is the scientific theory that describes the large-scale movement of Earth's lithosphere, which is divided into tectonic plates.

Front

What are tectonic plates?

Back

Tectonic plates are large, rigid pieces of the Earth's lithosphere that move and interact at their boundaries.

Front

What is the process of subduction?

Back

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

Front

What geological features can form at convergent plate boundaries?

Back

At convergent plate boundaries, features such as mountains, deep ocean trenches, and volcanic arcs can form.

Front

What is the difference between continental and oceanic crust?

Back

Continental crust is thicker and less dense than oceanic crust, which is thinner and denser.

Front

How do scientists use GPS in studying plate motion?

Back

Scientists use GPS to measure the movement of tectonic plates with high precision over time.

Front

What is the role of magma in plate tectonics?

Back

Magma can create new crust at divergent boundaries and can also cause volcanic eruptions when it rises to the surface.
