What is the inner core?

Back

The inner core is the innermost layer of the Earth, composed mainly of iron and nickel, and is solid due to the immense pressure.

Front

What is the outer core?

Back

The outer core is the layer of the Earth located outside the inner core, composed of liquid iron and nickel, and is responsible for Earth's magnetic field.

Front

What is the mantle?

Back

The mantle is the thick layer of the Earth located between the crust and the outer core, made of semi-solid rock that flows slowly.

Front

What is the crust?

How does the mantle affect tectonic plates?

Back

The mantle's semi-solid rock allows tectonic plates to float and move, causing earthquakes and volcanic activity.

Front

What is the significance of the Earth's crust?

Back

The Earth's crust is significant because it is where all terrestrial life exists and contains natural resources.

Front

What is the temperature of the inner core?

Back

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

Front

What is the composition of the outer core?

Back

The outer core is primarily composed of liquid iron and nickel.
