Q3 Benchmark Review/ Practice

What are the two main types of seismic waves?

• The two main types of seismic waves are P-waves, or primary waves, and S-waves, or secondary waves.

• The two main types of seismic waves are L-waves, or long waves, and R-waves, or Rayleigh waves.

• The two main types of seismic waves are T-waves, or tertiary waves, and Q-waves, or quaternary waves.

• The two main types of seismic waves are X-waves, or extra waves, and Y-waves, or yield waves.

Which type of seismic wave can travel through both liquids and solids?

• P-waves

• S-waves

• Both P-waves and S-waves

• Neither P-waves nor S-waves

Scientists cannot directly study Earth's layers because:

• they are too deep to access directly.

• they are constantly changing.

• they are made of unknown materials.

• they are too hot to study.

Using the graph, evaluate each statement and select whether the information is true or false. 1. The velocity of the P-wave decreased, and the S-wave became zero at 2900 km depth. True or False 2. The density of the layer changed at 2900 km depth. True or False 3. The S- and P-waves travel through the same speed in all layers of Earth. True or False 4. The layer at 4000 km depth is most likely made of liquid. True or False

• True

• False

• True

• False

• True

Why does Earth's core not show S-waves in the diagram?

• A. Earth's outer core is liquid.

• B. Earth's inner core is solid.

• C. Earth's outer core is solid.

• D. Earth's inner core is liquid.

Michelle studies the sample of rock shown below. Michelle decides that the sample is from a sedimentary rock. Which sentence explains why Michelle classifies the sample as sedimentary rock?

• The layers show that the rock was formed by a single element under high pressure.

• The layers show that the rock was formed by a single element under extreme heat.

• The layers show that the rock was formed by one or more minerals that cooled very quickly.

• The layers show that the rock was formed by one or more minerals that compacted over time.

The movement of tectonic plates has affected the current location of continents.

• By causing continents to drift apart or collide over millions of years.

• By keeping continents in a fixed position since their formation.

• By having no impact on the position of continents.

• By causing continents to shrink in size.
