Unit 3 LS3 Concept Review (Evaluate)

Sally is researching the differences that exist in each layer of the Earth. Which of the following best describes Earth's crust?

• Solid, rocky

• Liquid, metallic

• Semisolid, convecting

• Dense, extremely hot

Which is true about oceanic crust?

• It is thinner and less dense than continental crust

• It is thinner and more dense than continental crust

• It is thicker and more dense than continental crust

• It is thicker and less dense than continental crust

As you travel from the crust to the core, how would temperature, pressure and density of the material change?

• They would all increase

• They would all decrease.

• Nothing, the layers are made of the same material throughout

• Temperature would decrease, but pressure and density would increase

Which letter in the diagram identifies the layer of Earth made up of solid nickel and iron?

• layer A

• layer B

• layer C

• layer D

How have scientists been able to infer the internal structure of Earth without being able to directly observe inside the Earth?

• Scientists analyze how earthquake waves move throught Earth's interior.

• Scientists use satellite radar and sonar technologies to map Earth's internal layers.

• Scientists make educated guesses about Earth's internal structure based on previous hypothesis.

• Scientists study different types of rocks from many different locations on Earth's surface.

Why don't any s-waves travel through Earth's core?

• the outer core is liquid and s-waves can't travel through liquids

• the outer core is solid, and s-waves can't travel through solids

• the outer core is metallic and s-waves can't travel through metals

• the outer core is very hot, and s-waves can't travel through hot materials

• mountain building

• earthquakes

• convection currents

• water cycle

• subduction zones
