The Layers of the Earth

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.

Front

Is oceanic crust more dense than continental crust?

Back

True.

Front

What is the mantle?

Back

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

Front

What is the lithosphere?

Back

The lithosphere is the rigid rocky layer of the Earth that includes the crust and the uppermost part of the mantle.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle beneath the lithosphere, allowing tectonic plates to move.

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, made 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 each other, causing earthquakes and volcanic activity.

Front

What is the difference between oceanic and continental crust?

Back

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