What is gravity’s role as it relates to separation of the Earth’s layers?

Back

Gravity causes the denser materials to sink towards the center, forming the core, while less dense materials rise to form the crust and mantle.

Front

Which physical layer of the Earth is the most dense, has the highest temperature, and the most pressure?

Back

Inner Core

Front

What is Earth's Magnetic Field?

Back

A natural phenomenon that protects Earth from solar winds and is used in compasses and navigation systems.

Front

How is seismic wave data used to infer the composition of Earth’s interior?

Back

By measuring the speed and refraction of seismic waves, scientists can determine the density and state of materials inside Earth.

Front

What two theories were combined to create the theory of plate tectonics?

Back

Continental Drift and Seafloor Spreading.

Front

What is the composition of the Earth's crust?

Back

The Earth's crust is primarily composed of silicate rocks, including granite and basalt.

Front

What is the mantle, and what are its characteristics?

Back

The mantle is a thick layer of semi-solid rock between the crust and the outer core, characterized by convection currents that drive plate tectonics.

Front

What is the outer core made of?

Back

The outer core is composed of liquid iron and nickel, which generates Earth's magnetic field.

Front

What is the significance of the lithosphere?

Back

The lithosphere includes the crust and the uppermost mantle, forming the rigid outer layer of the Earth that is broken into tectonic plates.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the lithosphere that move and interact at their boundaries, causing geological activity.
