Earth's Structure

Front

What are the mechanical/physical layers of the Earth?

Back

The lithosphere, asthenosphere, mesosphere, inner core, and outer core.

Front

How does oceanic crust compare to continental crust?

Back

Oceanic crust is thinner, younger, and more dense than continental crust.

Front

What type of plate boundary is responsible for the Great Rift Valley and the Mid-Atlantic Ridge?

Back

Divergent plate boundary.

Front

What is the layer of the Earth that we live on?

Back

Continental Crust.

Front

What is the name of the plate labeled G in a geological map?

Back

South American Plate.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The semi-fluid layer beneath the lithosphere that allows tectonic plates to move.

Front

What is the difference between the inner core and outer core?

Back

The inner core is solid and composed mainly of iron and nickel, while the outer core is liquid.

Front

What is a convergent plate boundary?

Back

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

Front

What is a transform plate boundary?

Back

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