What is the outer core of the Earth?

Back

The outer core is a liquid layer composed mainly of iron and nickel, located beneath the mantle and above the inner core, with a depth of about 2,900 to 5,150 kilometers.

What is the depth of the outer core?

Back

The outer core can have a depth of about 4,000 kilometers.

Front

What is the pressure in the outer core?

Back

The pressure in the outer core can reach up to 2 million atmospheres.

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 composition of the inner core?

Back

The inner core is primarily composed of solid iron and nickel.

Front

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

Back

The outer core is liquid, while the inner core is solid due to the immense pressure.

Front

What is the asthenosphere?

Back

The asthenosphere is a semi-fluid layer of the upper mantle that lies beneath the lithosphere, allowing tectonic plates to move.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries, causing geological activity.

Front

What is the significance of the Eurasian Plate?

Back

The Eurasian Plate is one of the largest tectonic plates, covering parts of Europe and Asia, and is significant for its role in continental drift.

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 silicate rocks that are semi-solid.
