Mantle

The video explains the structure of Earth's layers, focusing on the mantle. It describes the mantle's composition of hot, rocky material under pressure, which affects its fluidity and mineral density. Despite high temperatures, the pressure keeps the inner mantle solid.

What are the main components of Earth's structure mentioned in the introduction?

• Mantle and core

• Outer crust and core

• Crust and mantle

• Crust and inner core

What is the mantle primarily composed of?

• Liquid water

• Hot, rocky material

• Metallic substances

• Gaseous elements

How does pressure affect the mantle's composition?

• It cools down the mantle

• It concentrates denser minerals at greater depths

• It causes the mantle to expand

• It makes the mantle more fluid

Why doesn't the mantle melt despite its high temperature?

• Due to the cooling effect of the core

• Due to the presence of water

• Because of its chemical composition

• Because of the pressure that makes it less fluid

What is the state of the inner mantle?

• Liquid

• Plasma

• Gaseous

• Solid
