Human Impact (Non-Water)

What is the cause of increased carbon dioxide in the atmosphere?

• burning fossil fuels

• breathing

• garbage

What is the main greenhouse gas?

• carbon dioxide

• oxygen

• nitrogen

• methan

The northern elephant seal was almost hunted to extinction in the 1800s. By the late 1890s, approximately one hundred seals were left, reducing the gene pool of the population. What will be the consequence of this reduction?

• Competition within the population will increase.

• The surviving elephant seals will be better able to adapt.

• Inbreeding will be less frequent among the remaining population.

• The elephant seals will be more vulnerable to environmental change.

Which of the following is a property of a nonrenewable resource?

• It will not run out no matter how much it is used.

• It takes tens of thousands to millions of years to replace if it is used up.

• It is recyclable after it is used through a quick and easy process.

• It releases oxygen into the atmosphere after it is used.

A ski resort installed a wind turbine  similar to those represented below to  supply some of  its energy needs. This turbine was most likely installed because wind power is:

• Renewable and does substantial  damage to the atmosphere.

• Renewable and does minimal  damage to the atmosphere.

• Nonrenewable and does substantial damage to the atmosphere.

• Nonrenewable and does minimal damage to the atmosphere

A scientist wanted to find out if low numbers of fish found in a nearby lake were related to acid rain. During his three-year study, he analyzed rainwater and lake water samples. By gathering samples of fish, he estimated the number of fish in the lake. Each year he found that both the rainwater and lake water became more acidic, and the number of fish decreased. His data suggested that acid rain may be responsible for the decrease in the number of fish found in the lake. 

What most likely led to the rainwater’s increasing acidity? 

• ultraviolet radiation 

• sedimentation 

• burning fossil fuels

•  global warming

Connect the piece of evidence with the reason it supports.

• Food Choices

• "Spills and leaks from oil pipelines or hydraulic fracturing (fracking) operations can degrade water supplies" (National Geographic).

• Water pollution

• "Most air pollution is created by people, taking the form of emissions from factories, cars, planes, or aerosol cans" (National Geographic).

• Fossil fuels

• "Some electric power plants run on nuclear energy, water power

  or wind power" (Drilling Deep for Knowledge).

• Overpopulation

• "Manure is one obvious pollutant associated with meat production" (CommonLit).

• Air pollution

• "Carbon dioxide waste builds up as more people burn fossil fuels for transportation and

  heating homes" (Growing World Population).

National Geographic claimed, "Thanks largely to decades of regulation and legal action against big polluters, the main cause of U.S. water quality problems is now "​ (a)   ," when pollutants are carried across or through the ground by rain or melted snow."

• Nonpoint Source Pollution
• Air Pollution
• Water Pollution
• Fossil Fuels
