Geosphere Review (Rocks, Earth's Layers, Pl. Tectonics, Rel Age)

Front

What are the layers of the Earth?

Back

The Earth has four main layers: the crust, mantle, outer core, and inner core.

Front

What is the primary method scientists use to study the Earth's interior?

Back

Scientists use seismic waves data to study the Earth's interior.

Front

What is a convergent boundary?

Back

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

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move apart from each other, often creating new crust as magma rises to the surface.

Front

What is the mantle?

Back

The mantle is the thick layer of the Earth located between the crust and the outer core, and it has the most volume of all Earth's layers.

Front

What is the outer core made of?

Back

The outer core is primarily made of liquid iron and nickel.

Front

How does the inner core differ from the outer core?

Back

The inner core is solid, while the outer core is liquid.

Front

What is the crust?

Back

The crust is the thin, outermost layer of the Earth, where we live.

Front

What is the significance of seismic waves in geology?

Back

Seismic waves help scientists understand the structure and composition of the Earth's interior.

Front

What happens at transform boundaries?

Back

At transform boundaries, two tectonic plates slide past each other, which can cause earthquakes.
