Earth's Crust Quiz

What is the Earth's outermost layer called?

• Mantle

• Lithosphere

• Asthenosphere

• Mesosphere

What are the two types of crust mentioned in the text?

• Basaltic and Granitic

• Oceanic and Continental

• Igneous and Metamorphic

• Sedimentary and Crystalline

Which type of crust is described as less dense and thick?

• Oceanic crust

• Continental crust

• Basaltic crust

• Granitic crust

What is the term used to describe the top layer of Earth when studying its chemical composition?

• Crust

• Lithosphere

• Asthenosphere

• Mantle

Why do continents float at a higher elevation than the ocean floor?

• Because continental crust is denser than oceanic crust

• Because continental crust is less dense than oceanic crust

• Because the asthenosphere is denser than the continental crust

• Because the oceanic crust is less dense than the asthenosphere

What does the law of superposition help scientists determine?

• The exact age of rock layers

• The relative age of rock layers

• The chemical composition of rock layers

What is an intrusion in geological terms?

• A type of rock layer found on the surface

• Magma that cools and solidifies underground

• A break in the rock where no movement has occurred

• A layer of rock that has been folded by stress

How can scientists tell that a fault is younger than the layers it cuts across?

• The fault causes the layers to fold

• The fault has different rock types than the layers

• The fault separates the layers, indicating it occurred after they were deposited

• The fault is always on the top layer

What is a fold in geological terms?

• A break in the rock where movement has occurred

• A layer of rock that has been eroded by water

• A bend in the rock caused by stress

• A type of rock that is resistant to stress
