Earth Layers

Front

What are the main layers of the Earth?

Back

The main layers of the Earth are the Crust, Mantle, Outer Core, and Inner Core.

Front

What is the Mantle?

Back

The Mantle is the thick layer of rock between the Earth's crust and outer core, responsible for convection currents.

Front

What is the difference between the Inner Core and Outer Core?

Back

The Inner Core is solid and composed mainly of iron and nickel, while the Outer Core is liquid and also made of iron and nickel.

Front

What causes convection currents in the Mantle?

Back

Convection currents in the Mantle are caused by heat from the Earth's core, primarily from radioactive decay and pressure.

Front

How do scientists study the Earth's interior?

Back

Scientists study the Earth's interior using seismic waves generated by earthquakes.

Front

What is the role of the Outer Core in Earth's magnetic field?

Back

The Outer Core generates the Earth's magnetic field through the movement of liquid iron.

Front

What is the Crust?

Back

The Crust is the thin, outermost layer of the Earth, composed of solid rock and minerals.

Front

What is the composition of the Inner Core?

Back

The Inner Core is primarily composed of solid iron and nickel.

Front

What is the significance of seismic waves?

Back

Seismic waves provide information about the Earth's internal structure and composition.

Front

What is the temperature range of the Earth's core?

Back

The temperature of the Earth's core can reach up to 5,700 degrees Celsius (10,300 degrees Fahrenheit).
