Earth's Interior

Front

What is the Earth's inner core?

Back

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

Front

What is the Earth's outer core?

Back

The Earth's outer core is a liquid layer composed mainly of iron and nickel, responsible for generating the Earth's magnetic field.

Front

What is the Earth's mantle?

Back

The mantle is the thick layer of rock between the Earth's crust and outer core, where convection currents occur.

Front

What is the Earth's crust?

Back

The Earth's crust is the outermost layer of the Earth, which is solid and relatively thin compared to the other layers.

Front

What are convection currents?

Back

Convection currents are movements within the mantle caused by the heat from the Earth's core, which drive the movement of tectonic plates.

Front

What materials primarily compose the Earth's inner core?

Back

The inner core is primarily composed of solid iron and nickel.

Front

What is the state of matter of the outer core?

Back

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

Front

How does the outer core contribute to the Earth's magnetic field?

Back

The movement of liquid iron and nickel in the outer core generates electric currents, which create the Earth's magnetic field.

Front

Which layer of the Earth is the thickest?

Back

The mantle is the thickest layer of the Earth.

Front

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

Back

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