Unit 3 Flashcard Review

Front

What is the definition of stress in the context of geology?

Back

Stress is a force that acts on a rock, causing deformation.

Front

What is strain in geological terms?

Back

Strain is the deformation that occurs in a rock as a result of stress.

What is a transform plate boundary?

Back

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

Front

What is the outer core of the Earth?

Back

The outer core is a liquid layer composed mainly of iron and nickel, located beneath the mantle and above the inner core.

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

How does the thickness of continental crust compare to oceanic crust?

Back

Continental crust is generally thicker than oceanic crust.

Front

What is the role of tectonic plates in the Earth's geology?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact, causing geological phenomena such as earthquakes and volcanic activity.

What happens at a divergent plate boundary?

Back

At a divergent plate boundary, tectonic plates move apart, leading to the formation of new crust, often seen at mid-ocean ridges.
