• It is the thickest layer.

• It is made of liquid iron.

Which layer of the Earth is responsible for shaping the crust and forming features like volcanoes?

• The crust

• The outer core

• The mantle

• The inner core

What is the main function of the Earth's outer core?

• To provide nutrients to the mantle

• To generate the magnetic field

• To support the crust

• To cool the inner core

How do scientists learn about the structure of the Earth's layers?

• By observing the ocean floor

• By analyzing seismic waves

• By studying volcanic eruptions

What role does the Earth's inner core play in relation to the outer core?

• It causes earthquakes

• It cools the outer core

• It helps generate the magnetic field

• It supports the mantle
