Earth's Layers

Front

What is the asthenosphere?

Back

The asthenosphere is a plastic-like layer of the Earth located beneath the lithosphere, allowing the crust to flow over it.

Front

What two parts make up the lithosphere?

Back

The lithosphere is made up of the crust and the upper mantle.

Front

Which layer of the Earth is entirely liquid?

Back

The outer core is the only entirely liquid layer of the Earth.

Front

What creates the Earth's magnetic field?

Back

The Earth's magnetic field is created by the outer core, where liquid material spins around the solid inner core.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the lithosphere that move and interact with each other.

Front

What is the composition of the Earth's crust?

Back

The Earth's crust is composed of solid rock and is divided into continental and oceanic crust.

Front

What is the role of the inner core?

Back

The inner core is a solid layer made primarily of iron and nickel, contributing to the Earth's magnetic field.

Front

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

Back

The outer core is liquid, while the inner core is solid.

Front

What is the mantle?

Back

The mantle is the layer of the Earth located between the crust and the outer core, composed of semi-solid rock.

Front

How do convection currents in the mantle affect the Earth's surface?

Back

Convection currents in the mantle drive the movement of tectonic plates, leading to earthquakes and volcanic activity.
