Earth - Final Exam Review #2

Which part of Earth's interior is inferred to have convection currents that cause tectonic plates to move?

• Astehnosphere
• Outer Core
• Inner Core
• Ridgid Mantle

Base your answer on the diagram below, which shows models of two types of earthquake waves. Model A best represents the motion of earthquake waves called

• P-waves (compressional waves) that travel faster than S-waves (shear waves) shown in model B

• P-waves (compressional waves) that travel slower than S-waves (shear waves) shown in model B

• S-waves (shear waves) that travel faster than P-waves (compressional waves) shown in model B

• S-waves (shear waves) that travel slower than P-waves (compressional waves) shown in model B

The circles on the map below show the distances from three seismic stations, X, Y, and Z, to the epicenter of an earthquake. Which location is closest to the earthquake epicenter?

• C

• D

• A

Water warmed by solar energy near the equator expands and is less dense than cold water. Cold water at poles is denser, and sinks, and moves very slowly beneath warmer ocean water toward the equator. The reason for this is because

• Warm molecules rise and cold molecules fall creating convection currents throughout the oceans around the globe.
• Cold molecules rise and warm molecules fall
• Cold molecules override warm molecules causing them to expand
• Warm molecules shrink causing cold molecules to push them out to deeper waters

A community decides to upgrade its water purification and management systems. What lasting impact could this have on available freshwater?

• It could cause an increase in the freshwater supply
• It could cause a decrease in water demand
• It could cause a decrease in the water levels
• It could cause an increase in waterborne diseases

Why would an environmental group be against building a landfill in an area?

• The landfill could leak and contaminate the local water supply.
• Methane gas from the landfill could help generate electricity.
• The landfill would attract too many scavenging birds.
• The smell of a landfill would keep many native animals away.

The drilling for freshwater increases along a coastal area. What is a likely consequence of this action?

• An intrusion of salt water into aquifers.
• The loss of water resources in estuaries.
• The destruction of estuaries because of an increase in sea levels.
• A decrease in salt concentration in inlet waterways
