Plate Boundaries Earthquake Scale Review

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, causing earthquakes.

What happens at a divergent plate boundary?

Back

At a divergent plate boundary, tectonic plates move away from each other, leading to the formation of new crust.

Front

What is convection in the context of plate tectonics?

Back

Convection is the process by which heat from the Earth's interior causes the movement of tectonic plates.

Front

Name a real earthquake magnitude scale.

Back

Moment Magnitude Scale, Richter Scale, and Mercalli Scale are real earthquake magnitude scales.

Front

What is the lithosphere?

Back

The lithosphere is the outermost, rigid layer of the Earth, consisting of the crust and the upper mantle, divided into tectonic plates.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often causing one plate to be forced beneath the other.

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate moves under another, leading to volcanic activity and earthquakes.

Front

What is the difference between the Richter Scale and the Moment Magnitude Scale?

Back

The Richter Scale measures the amplitude of seismic waves, while the Moment Magnitude Scale measures the total energy released by an earthquake.

Front

What is the Mercalli Scale?

Back

The Mercalli Scale measures the intensity of an earthquake based on its observed effects and damage.

Front

What is the asthenosphere?

Back

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