Unit 3 Final Exam Review

Students are performing an experiment to test the properties of water. They place five white flowers into five cups that contain dyed water.  They leave the flowers in the cups for a few days and record the results.  The image shows the experiment setup.

Which property of water are the students MOST LIKELY trying to show by performing the experiment?

• Capillary action, because it shows how colored dye will float above the water.

• Surface tension, because it shows how colored dye will float above the water.

• Capillary action, because it shows the movement of dyed water against gravity.

• Surface tension, because it shows the movement of dyed water against water.

Students create a model to understand the movement of warm and cold water in the ocean.

Based on this model, what impact should the model show about the role of ocean currents in global climate?

• Ocean currents only influence local weather patterns without affecting global climate.

• Warm ocean currents redistribute thermal energy, leading to milder climates in polar regions and more extreme temperatures at the equator.

• Cold ocean currents cause increased precipitation and humidity in coastal regions, affecting global wind patterns.

• Ocean currents act as a global conveyor belt, redistributing heat from the equator to the poles, which helps regulate temperatures across different latitudes.

Students are performing several experiments to test the properties of water. Which experiment is MOST LIKELY testing the surface tension of water?

• Students mix different substances into water and determine which substance will dissolve.

• Students try different methods to determine the best way to get a paper clip to float on water's surface.

• Students research the density of different states to determine why solid water floats in liquid water.

• Student heat water over a hot plate and record water's surface temperature when it begins to form water vapor.

One characteristic that is unique to water is that it

• has a low specific heat

• can be changed from a liquid to a solid.

• dissolves very few substances

• exists naturally in three states on Earth

Which of these is a property of water that allows it to transport materials through Earth’s systems?

• It expands as it solidifies.

• It is transparent.

• It dissolves many substances.

• It is a compound.

The graph shows the trend in global temperature and carbon dioxide emissions since 1880.

If the release of carbon dioxide emissions from human activities decreases the amount of carbon dioxide in the atmosphere by 20 ppm, what will be the likely effect on global temperature?

• Global temperature will decrease by 20°F.

• Global temperature will increase by 20°F.

• Global temperature will decrease by 0.20°F.

• Global temperature will increase by 0.20°F.

The model shows an exchange of carbon in the atmosphere in peta-grams of carbon.

What can be inferred based on an analysis of the model?

• More carbon is released by the ocean than is being absorbed.

• Excessive vegetation growth is increasing the amount of carbon in the atmosphere.

• Excessive use of fossil fuels is disturbing the balance of carbon in the atmosphere.

• Changing land use has the greatest impact on atmospheric carbon.
