Layers of the Earth

Front

What is the outer core of the Earth?

Back

The outer core is a layer of the Earth composed primarily of liquid metal, located beneath the mantle and above the inner core.

Front

What drives the movement of tectonic plates?

Back

The movement of tectonic plates is driven by convection currents in the asthenosphere, which is a semi-fluid layer of the mantle.

Front

Which layer of the Earth is the thinnest?

Back

The crust is the thinnest layer of the Earth, making up only a small fraction of the Earth's total volume.

Front

What layer of the Earth do humans live on?

Back

Humans live on the crust, which is the outermost layer of the Earth.

Front

What is a subduction zone?

Back

A subduction zone is a region where one tectonic plate slides under another, often leading to volcanic activity and earthquakes.

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 solid rock that flows slowly.

Front

What is the inner core?

Back

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

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is thinner and denser than continental crust, which is thicker and less dense.

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.

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.
