What is the significance of the mantle in Earth's structure?

• It is the thinnest layer of the Earth.

• It is the thickest layer and is involved in tectonic movements.

• It is primarily composed of liquid water.

• It is the outermost layer that protects the Earth from solar radiation.

• Outer core

• Mantle

• Inner core

• Crust

What is the theory of continental drift?

• The idea that continents are fixed in place.

• The hypothesis that continents have moved over geological time.

• The belief that continents are made of different materials.

• The theory that continents will eventually merge into one landmass.

What is the primary composition of the Earth's crust?

• Igneous rocks

• Silicate rocks

• Metamorphic rocks

How does the temperature change as you move from the crust to the inner core?

• Temperature decreases with depth.

• Temperature remains constant throughout.

• Temperature increases with depth.

• Temperature fluctuates randomly.
