ES Semester 1 menu Layers of the earth

What are the large, rigid slabs that make up the Earth's lithosphere called?

• Continents

• Oceans

• Tectonic plates

• Mountains

Which layer of the Earth, composed primarily of molten iron and nickel, is responsible for generating the planet's magnetic field?

• Crust

• Upper mantle

• Outer core

• Inner core

What distinguishes the Earth's mantle from its core in terms of composition and material properties?

• The mantle is solid, while the core is liquid

• The mantle is composed of silicate rocks, while the core is composed of iron and nickel

• The mantle is hotter than the core

• The mantle is denser than the core

What is the outermost layer of the Earth called?

• Crust

• Mantle

• Outer core

• Inner core

Which layer of the Earth is composed primarily of solid rock and is located directly beneath the crust?

• Crust

• Mantle

• Outer core

• Inner core

What is the primary composition of the Earth's inner core?

• Silicate rocks

• Molten iron and nickel

• Solid iron and nickel

• Liquid magma

What is the asthenosphere primarily composed of?

• Solid rock

• Molten rock

• Liquid water

• Gaseous elements

How does the asthenosphere contribute to the movement of tectonic plates?

• By providing a rigid surface for plates to rest on

• By acting as a lubricating layer that allows plates to move

• By generating magnetic fields that push plates

• By creating gravitational forces that pull plates
