What is the temperature range of the outer core?

Back

The temperature of the outer core ranges from about 4,000 to 6,000 degrees Celsius.

Front

What is the difference between the lithosphere and the asthenosphere?

Back

The lithosphere is the rigid outer layer of the Earth, while the asthenosphere is a semi-fluid layer beneath it.

What role does the outer core play in Earth's magnetic field?

Back

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