Unit 3a Hydrosphere Part 1 Quizs Reviewer

Why do land breezes occur at night?

• Land cools off slower than water, so the air above water is cooler.
• Water cools off faster than land, so the air above land is warmer.
• Land heats up slower than water, so the air stays cooler during the day.
• Water cools off slower than land, so the air above water is warmer.

This image demonstrates that

• There is a direct correlation with the atmospheric CO₂ and the CO₂ in seawater

• That pH of the ocean increases as the atmospheric CO₂ increases

• That there is no correlation between pH of the ocean and atmospheric CO₂

Where does most water vapor in the air come from?

• transpiration
• evaporation from groundwater
• evaporation from oceans
• precipitatoin

In this model of layers of water, what can you infer about the red layer of water?

• It is warmer than the yellow, green, and blue layers

• It is colder than the yellow, green, and blue layers

• It is higher in salinity than the yellow, green, and blue layers

• It is higher in salinity and warmer than the other layers

An example of a marine organism that needs calcium carbonate 

• a crab
• a shark
• an octopus

How will the melting of icecaps change the salinity of ocean water?

• raise the salinity
• lower the salinity
• no change to the salinity
• I have no idea

Very slight increases in the acidity of seawater __________  marine organisms that make shells.

• doesn't bother
• has no effect on 
• is unhealthy and stresses

What causes tides?

• wind
• differences in density
• gravity from the moon
• plate tectonics

How does the moon affect Earth?

• it causes plate tectonics
• it causes tides
• it causes wind
• it causes the weather

In areas where the land meets the sea, convection currents cause...

• tornadoes

• tsunamis

• eathquakes

• breezes
