Layers of the Earth

Front

What is the core of the Earth?

Back

The core is the innermost layer of the Earth, located at the center, composed mainly of iron and nickel.

Front

What is convection in the context of Earth's layers?

Back

Convection is the process where hot magma rises and cooler magma sinks within the mantle, causing movement of tectonic plates.

Front

What are the layers of the Earth in order from the surface?

Back

The correct order is: crust, mantle, outer core, inner core.

Front

What is the theory of plate tectonics?

Back

The theory that explains how pieces of Earth's crust are in constant, slow motion due to convection currents in the mantle.

Front

What is the crust of the Earth?

Back

The crust is the outermost layer of the Earth, where we live, consisting of solid rock.

Front

What is the mantle?

Back

The mantle is the layer between the crust and the core, made of semi-solid rock that flows slowly.

Front

What is the outer core?

Back

The outer core is a liquid layer of the Earth located beneath the mantle, composed mainly of iron and nickel.

Front

What is the inner core?

Back

The inner core is the solid innermost layer of the Earth, extremely hot and under immense pressure.

Front

What causes tectonic plates to move?

Back

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