Earth's Layers

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, consisting of solid rock. It is divided into two types: continental crust and oceanic crust.

What are the two types of crust?

Back

The two types of crust are oceanic crust and continental crust.

Front

What is the oceanic crust?

Back

The oceanic crust is the part of the Earth's crust that underlies the ocean basins. It is thinner and denser than continental crust.

Front

What is the continental crust?

Back

The continental crust is the part of the Earth's crust that forms the continents. It is thicker and less dense than oceanic crust.

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, which includes 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, allowing for the movement of 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 that flows slowly.

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, and is responsible for Earth's magnetic field.

What is the inner core?

Back

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

Front

What are convection currents?

Back

Convection currents are the movement of fluid caused by differences in temperature and density, which can occur in the mantle and outer core.
