Layers of the Earth

Front

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.

Front

What is the asthenosphere?

Back

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

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 is the thickest layer of the Earth?

Back

The mantle is the thickest layer of the Earth, making up about 84% of the Earth's total volume.

Front

What is the inner core?

Back

The inner core is a solid sphere composed mainly of iron and nickel, located at the center of the Earth.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological activity.

What is the difference between the crust and the mantle?

Back

The crust is the thin, solid outer layer of the Earth, while the mantle is a thicker layer beneath the crust that is semi-solid and allows for convection.

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 the Earth's magnetic field through the dynamo effect.

Front

What is the African Plate?

Back

The African Plate is a tectonic plate straddling the equator as well as the prime meridian, covering much of Africa.
