Exam 9: Global Atmospheric Changes

While there has been success in addressing ozone depletion and acid deposition, ecosystems have not yet recovered. What is the reason for this slow recovery? As part of your answer also describe some strategies that were employed to reduce these pollution problems.

Discuss the process of acid deposition and the human activities that cause this problem. What are some of the impacts that acid deposition has had on the abiotic and biotic components of the environment over the past thirty years?

Since 1991 acid deposition in some areas of the United States and Canada have been reduced by as much as 35 percent.

The amount of water vapor in the atmosphere, geographic location, and topographic features are all responsible for differences observed in precipitation.

The computer models below show acidity of ocean waters in 1995 and 2100. What can be interpreted from the models about ocean acidification? 1. Plant and animals in the Arctic and Antarctic are likely to be the first and also the most affected by ocean acidification. 2. Since coral reefs are susceptible to acid bleaching, if water acidity around the equator increases as projected then coral reefs will be affected.

Human activities have increased the levels of carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and tropospheric ozone in the atmosphere.

What is a rain shadow?

Which of the following statements about sea level rise is false?

The ______ is/was an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion.

Even though the data linking climate change to disease outbreak is still circumstantial, diseases such as ___ are predicted to increase due to changes associated with global warming.

Which of the following activities is responsible for the largest percentage of human-made carbon dioxide emissions?

_____________ is the separating and capturing of carbon dioxide produced during the combustion of fossil duels?

The figure below is of a new innovation in electricity generation from coal. If this technology works as indicated in the figure, we could accomplish the following: Precombustion (decarbonization)Capture

Nitrogen oxide emissions are harder to control than sulfur dioxide emissions because motor vehicles produce a substantial portion of nitrogen oxides.

Which of the following does not contribute to ozone depletion?

Even if all burning of fossil fuels was stopped today, why will temperatures continue to increase?

The cooling effects of atmospheric aerosols are much weaker than the warming from an enhanced greenhouse effect for all of the following reasons except:

Describe the difference between mitigation and adaptation as strategies that can be used to deal with global climate change. Discuss the strengths of each strategy and give two examples of each strategy can be implemented.

Which greenhouse gas that is released as the tundra thaws?

Which of the following is not a greenhouse gas:
