(06.02 LC)Complete the sentence. Fracking collects ________ that forms when organic matter is compressed under great temperature and pressure for millions of years.

(04.03 LC)Which of the following would result from sulfurous smog?

(04.06 MC)Which of the following options can be added to a national climate plan to help protect communities from sea level rise?

(04.02 LC)Complete the sentence: Surface ocean currents are driven by ________.

(04.05 HC)The graph shows how much sea levels changed from about 1870 to 2018. Items with pluses (+) are factors that caused ice to melt and sea levels to increase globally, while minuses (−) are variables that caused sea levels to decrease. These items are displayed at the time they were affecting sea level.© 2021 NASA’s Goddard Space Flight CenterWhich factor led to an increase in sea levels between 1960 and 1980?

(04.02 LC)Complete the sentence. Surface ocean density is determined by ________.

(04.07 MC)Which of the following global changes will have the most impact on New York City?

(04.07 HC)Read the following case study:When carbon-dioxide-rich air meets seawater containing less carbon dioxide, the greenhouse gas diffuses from the atmosphere into the ocean as irresistibly as a ball rolls downhill. Today, about a quarter of human-produced carbon dioxide emissions get absorbed into the ocean. Once the carbon is in the water, it can stay there for hundreds of years.Warm, carbon-rich surface water flows in ocean currents to colder parts of the globe, releasing its heat along the way. In the polar regions, the now-cool water sinks several miles deep, carrying its carbon burden to the depths. That’s good for the atmosphere, but the ocean pays a heavy price for absorbing so much carbon: acidification. Carbon dioxide reacts chemically with seawater to make the water more acidic.(Source: climate.nasa.gov)Which statement best explains how the global changes in the case study could impact humans?

(04.03 LC)Sulfur oxide is a type of pollution that comes from

(04.07 HC)Read the following case study:Through the North American Forest Dynamics project, and a dataset based on Landsat imagery released earlier this month, researchers can track where tree cover is disappearing through logging, wildfires, windstorms, insect outbreaks, drought, mountaintop mining, and people clearing land for development and agriculture. Equally, they can see where forests are growing back over past logging projects, abandoned croplands and other previously disturbed areas.In the Southeast, fast-growing tree farms illustrate a human influence on the forest life cycle. In the West, however, much of the forest disturbance is directly or indirectly tied to climate. Wildfires stretched across more acres in Alaska this year than they have in any other year in the satellite record. Insects and drought have turned green forests brown in the Rocky Mountains. In the Southwest, pinyon-juniper forests have died back due to drought.(Source: climate.nasa.gov)Which statement best explains how the global changes in the case study could impact humans?
