8.4 Earth's Interior

Front

What is the outer core of the Earth?

Back

The outer core is a layer of the Earth's interior that is composed of liquid material, primarily iron and nickel.

Front

What evidence do scientists use to study the interior of the Earth?

Back

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

Front

What type of wave can travel through the outer core?

Back

P-Waves (Primary Waves) can travel through the outer core.

Front

What is the asthenosphere?

Back

The asthenosphere is a layer of the Earth's mantle that is plastic and has a consistency similar to silly putty, allowing for movement.

Front

What are the layers of the Earth?

Back

The Earth is made up of several layers: the crust, mantle, outer core, and inner core.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, generated by earthquakes or other geological processes.

Front

What is the difference between P-Waves and S-Waves?

Back

P-Waves are compressional waves that can travel through solids and liquids, while S-Waves are shear waves that can only travel through solids.

Front

What is the inner core of the Earth?

Back

The inner core is the solid, innermost layer of the Earth, primarily composed of iron and nickel.

Front

What is the mantle?

Back

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