Amplify Plate Motion Assessment

Front

What is plate tectonics?

Back

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

Front

What happens at a convergent boundary?

Back

At a convergent boundary, two tectonic plates move toward each other, which can cause one plate to be forced beneath the other, leading to subduction.

Front

What is subduction?

Back

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

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often resulting in the formation of new crust.

Front

What is the role of GPS in studying plate motion?

Back

GPS is used to measure the precise movements of tectonic plates over time, helping scientists understand plate tectonics.

Front

What is the significance of fossil distribution in understanding plate tectonics?

Back

Fossils found on different continents can indicate that those continents were once connected, supporting the theory of plate tectonics.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere.

Front

What is volcanic activity?

Back

Volcanic activity refers to the eruption of magma from beneath the Earth's crust, which can create new landforms.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper mantle.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle beneath the lithosphere, allowing tectonic plates to move.
