"1.According to the graph, Earth's ________ accumulated the least amount of energy during the 1970-2010 time period. [ ]atmosphere [ ]land [ ]ice [ ]ocean

2.The graph shows that Earth's ________ absorbed most of the energy accumulated by the planet's climate system during the 1970-2010 period. [ ]atmosphere [ ]land [ ]ice [ ]ocean

3.The graph shows that of the total energy absorbed by the ocean, about two-thirds accumulated in the ________ ocean. [ ]upper [ ]lower

4.For the energy content changes shown in Figure 1, the estimated values were all positive. The positive energy change implies that these parts of the global climate system ________. [ ]all cooled [ ]some cooled and some warmed [ ]all warmed

5.Compared with the ocean's energy content change, the changes of all the other parts of the climate system combined were ________. [ ]much smaller [ ]about the same [ ]much greater

6.If the top solid line showing the total accumulation of heat energy by all of the Earth's climate system components were highly smoothed by a running average technique, it would not form a straight line. Rather, it would curve upward as time progresses. [Looking at the graph at an oblique angle from its lower left corner would show this.] Such curvature implies that the annual rate at which heat energy was being added to Earth's climate system was generally ________ over time. [ ]decreasing [ ]steady [ ]increasing 7.The temperature change of ocean water leads to changes in evaporation and density. Evaporation from the ocean drives the global water cycle. Warmer water has more energy available for evaporation. In locations where precipitation is less than evaporation, we would expect that excess evaporation would lead to surface ocean waters that become ________ saline (as salts are left behind in the evaporation process). [ ]less [ ]more

8.As seawater warms, it becomes less dense. Less dense water means that the same mass of water would occupy a greater volume. The result of a warming ocean would be ________ sea level. [ ]rising [ ]lowering .

9.Examine the temperature changes in the upper 100 m of the ocean. The color coding indicates the across the ocean in the upper 100 m, temperatures have generally ________. [ ]fallen [ ]remained the same [ ]risen

10.The greatest negative per decade temperature change has occurred in the world ocean at a depth of about ________. [ ]2000 m at the higher northern latitudes [ ]2000 m at the higher southern latitudes [ ]200 m at the equatorial latitude

11.In general, surface and near-surface ocean waters have become ________. [ ]saltier in the lower latitudes [ ]fresher in the higher latitudes [ ]both of these On page 301, the

12.As seen in this investigation, the role of the ocean ________ be ignored when seeking a more complete understanding of Earth's climate system and climate change. [ ]can [ ]cannot

13.The ocean plays a ________ role in the climate system through its cycling of mass and energy. [ ]minor [ ]major "
