Environmental Impact U9

One important drawback of the use of HCFCs as a replacement for CFCs is that HCFCs

• biomagnify in food chains in the Arctic ecosystem

• combine with water vapor to form acid precipitation

• are greenhouse gases that contribute to climate change

• react with carbon monoxide (CO) to form ozone in the troposphere

HCFCs were originally introduced as a solution to help phase out the use of CFCs. Which of the following most likely contributed to the increased levels of HCFCs in the stratosphere over the past 30 years?

• Thermal inversions in the troposphere

• Conversion of CO₂ to HCFCs in the troposphere

• Reduced albedo in the Arctic because of climate change

• Leaking of refrigeration and air-conditioning units

Based on the information in the map, which areas in the United States have experienced the greatest sea level rise?

• The Northeast and the Gulf of Mexico

• The Southeast and the West Coast

• The state of California and the state of Hawaii

• The Pacific Northwest and the state of Alaska

Coastal areas will experience a decrease in the rates of erosion and water pollution in response to sea level rise because of an increase in the absorption of nutrients from agricultural areas.

• True

• False

• Not enough information

• None of the above

There will be a decrease in the number of respiratory and cardiovascular illnesses along the coasts because there will be an increase of water vapor in the atmosphere from the rising sea level.

• True

• False

• Not enough information

• None of the above

There will be an increase in the number of individuals who live in flood prone regions, and there will be an increase in the number of properties at risk of flooding.

• True

• False

• Not enough information

• None of the above

• Temperatures were the same 125,000 years ago as they are today.

• Temperatures were warmer 125,000 years ago than the average temperature over the past 400,000 years.

• Temperatures were cooling at a rate 125,000 years ago that was unprecedented compared to the rate over the past 400,000 years.
