Layers of the 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 the semi-fluid layer of the mantle located beneath the lithosphere, where convection currents occur.

What causes tectonic plates to move?

Back

Tectonic plates move due to convection currents in the mantle, which are caused by the heat from the Earth's core.

What is the difference between the lithosphere and asthenosphere?

Back

The lithosphere is solid and rigid, while the asthenosphere is semi-fluid and allows for the movement of tectonic plates.

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, which includes both continental and oceanic crust.

What is the mantle?

Back

The mantle is the thick layer of the Earth located between the crust and the core, composed of semi-solid rock.

Front

What is the outer core?

Back

The outer core is the liquid layer of the Earth's core, composed mainly of iron and nickel.

Front

What is the inner core?

Back

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

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with one another.

What is convection?

Back

Convection is the process of heat transfer through the movement of fluids, which drives the movement of tectonic plates.
