earths layers

Front

What are Primary waves (P-waves)?

Back

Compression waves that travel through solids and liquids, compressing and expanding the material they pass through, temporarily changing volume.

Front

What is the outer core?

Back

The layer that lies beneath the mantle and surrounds the inner core.

Front

What layers of Earth make up the lithosphere?

Back

The crust and upper mantle.

Front

What is the crust?

Back

The outermost solid layer of the Earth.

Front

Where do convection currents occur in the Earth?

Back

In the Asthenosphere.

Front

What is the mantle?

Back

The layer of the Earth located between the crust and the outer core.

Front

What is the inner core?

Back

The innermost layer of the Earth, composed of solid iron and nickel.

Front

What are seismic waves?

Back

Waves of energy that travel through the Earth, often as a result of earthquakes.

Front

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

Back

S-waves (Secondary waves) can only travel through solids, while P-waves (Primary waves) can travel through both solids and liquids.

Front

What is the asthenosphere?

Back

A semi-fluid layer of the mantle where convection currents occur.
