Coffin's High School -Earth's Compositional and Physical Layers

Front

What is the lithosphere?

Back

The lithosphere is the outermost physical layer of the Earth, consisting of the crust and the uppermost part of the mantle. It is where life exists.

Front

What is the mantle?

Back

The mantle is the compositional layer of the Earth located between the crust and the outer core. It is where convection currents occur, driving plate tectonics.

Front

What is the outer core?

Back

The outer core is a physical layer of the Earth that lies beneath the mantle and surrounds the inner core. It is responsible for generating Earth's magnetic field.

Front

What happens to temperature as you move deeper into the Earth?

Back

As you move from the crust to the core, the temperature increases due to the pressure and heat generated from the Earth's interior.

Front

What is the mesosphere?

Back

The mesosphere is the physical layer of the Earth located between the asthenosphere and the outer core. It is characterized by increased pressure and temperature.

Front

What is convection?

Back

Convection is the process of heat transfer through the movement of fluids (liquids and gases) caused by differences in temperature and density.

Front

What is the asthenosphere?

Back

The asthenosphere is a semi-fluid layer of the upper mantle that lies beneath the lithosphere. It allows for the movement of tectonic plates.

Front

What is the inner core?

Back

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

Front

What is the Earth's magnetosphere?

Back

The magnetosphere is the region around the Earth dominated by its magnetic field, which protects the planet from solar wind and cosmic radiation.

Front

What is the difference between the crust and the mantle?

Back

The crust is the thin, outermost layer of the Earth, while the mantle is a thicker layer beneath the crust, composed of semi-solid rock.
