Plate Tectonics Review

Front

What is the outer core of the Earth?

Back

The outer core is a layer of Earth made entirely of molten rock with temperatures up to 6000 degrees Celsius.

Front

What is the crust of the Earth?

Back

The crust is the outermost layer of rock on Earth, especially the part above the mantle.

Front

What are the Mid-Ocean Ridges?

Back

Mid-Ocean Ridges are chains of seafloor mountains that wrap around the Earth, resembling the seam of a baseball.

Front

What is an example of direct evidence in geology?

Back

Rock samples are an example of direct evidence.

Front

What evidence supports the theory of continental drift?

Back

Evidence includes land features, fossils, and climate change.

Front

What is the mantle?

Back

The mantle is the layer of Earth located between the crust and the outer core, composed of semi-solid rock.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other.

Front

What is subduction?

Back

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

Front

What is a transform boundary?

Back

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

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often creating new crust.
