Structure 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 uppermost part of the mantle.

What is the thinnest layer of the Earth?

Back

The crust is the thinnest layer of the Earth.

Front

What is the asthenosphere?

Back

The asthenosphere is the layer of the Earth located beneath the lithosphere, made of flexible and semi-solid rock that can flow.

Front

What is the lithosphere made of?

Back

The lithosphere is made of rigid, solid rock that forms the tectonic plates.

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 core of the Earth?

Back

The core is the innermost layer of the Earth, consisting of a solid inner core and a liquid outer core, primarily made of iron and nickel.

Front

What are tectonic plates?

Back

Tectonic plates are large pieces of the lithosphere that move and interact at their boundaries, causing geological activity.

Front

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

Back

The inner core is solid due to immense pressure, while the outer core is liquid and allows for the movement of molten metal.

Front

What is the role of the mantle in plate tectonics?

Back

The mantle's convection currents drive the movement of tectonic plates in the lithosphere.
