Earth's Layers

Front

What is the inner core of the Earth?

Back

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

Which layer of the Earth is the thickest?

Back

The mantle is the thickest layer of the Earth, lying between the crust and the outer core.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, composed of the crust and the uppermost part of the mantle, and is solid.

Front

What is the asthenosphere?

Back

The asthenosphere is the layer of the Earth located directly below the lithosphere, characterized by its semi-fluid, plastic-like properties.

Front

What is the outer core?

Back

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

Front

What is the primary composition of the Earth's crust?

Back

The Earth's crust is primarily composed of solid rock, including both continental and oceanic crust.

Front

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

Back

The inner core is solid due to immense pressure, while the outer core is liquid and allows for the movement of molten metals.

Front

What is a model that represents the inner and outer core?

Back

A metal ball bearing (solid) suspended in oil (liquid) best represents the inner and outer core of the Earth.

Front

What is the role of the mantle in Earth's geology?

Back

The mantle plays a crucial role in tectonic activity, as it is involved in the movement of tectonic plates.
