Physical Layers of Earth

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The asthenosphere is a semi-fluid layer of the mantle beneath the lithosphere, where rocks can flow slowly.

Front

What is the mesosphere?

Back

The mesosphere is the layer of the Earth's mantle located below the asthenosphere, characterized by increasing pressure and temperature.

Front

What is the outer core?

Back

The outer core is a liquid layer of the Earth located beneath the mantle and above the inner core, primarily composed of iron and nickel.

Front

What is the inner core?

Back

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

Front

How does the lithosphere differ from the asthenosphere?

Back

The lithosphere is rigid and solid, while the asthenosphere is semi-fluid and can flow.

Front

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

Back

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

Front

What materials primarily make up the Earth's inner core?

Back

The inner core is primarily made up of iron and nickel.

Front

What happens to temperature and pressure as you go deeper into the Earth?

Back

Both temperature and pressure increase as you go deeper into the Earth.

Front

What is the role of the outer core in Earth's magnetic field?

Back

The movement of liquid iron in the outer core generates Earth's magnetic field.
