Which of the following is an effect of ozone layer depletion?

CONCEPT

Impacts of Air Pollution 2 What increasing greenhouse gas is of particular concern because it is so potent?

CONCEPT

• Carbon dioxide • Ozone • Methane • Nitrogen • Levels of lead, radon or asbestos increase.• Bodies of water become acidic, disrupting ecosystems.• There is an increased rate of skin cancer.• Emphysema, asthma and bronchitis are more prevalent.

Causes of Climate Change 3 Current climate change is occurring because .

•

carbon dioxide and methane emit radiation that cannot return to space •

clouds and reflective surfaces on Earth absorb radiation and the atmosphere warms •

the amount of energy from the sun varies and the heat from radiation can be trapped •

greenhouse gases absorb and redirect radiation back into the atmosphere

CONCEPT

Climate Change 4 Choose the statement that accurately describes natural gas.

CONCEPT

Non-Renewable Energy 5 Which of the following describes a stationary source of air pollution?

• Methane is among the digestive gases emitted by cattle on a nearby farm.• The dry cleaner in town has been in business for 45 years.• Use of this energy source relies upon mined minerals and heat from radioactive decay.• Fracking has expanded access to methane that occurs naturally in underground pockets.• It is widely used to heat water boilers, the steam from which drives a turbine that produces electricity.• This liquid energy source has a number of different uses, from fuel to plastics.

•

Paul takes his motorcycle for a drive around the lake.•

Car exhaust from tourists’ vehicles is a concern for many in the community.

CONCEPT

Air Pollution 6 Choose the statement about the Kyoto Protocol that is FALSE.

CONCEPT

Efforts to Address Climate Change 7 Cassie pulled the boat onto the ice and adjusted its sails. Once she got started she would be able to steer, change direction and control her speed with a few twists of the ropes. Giving the boat a mighty heave across the ice, Cassie jumped in.What kind of energy will Cassie use to power the boat?

• Hydroelectric • Wind • Geothermal • • The Kyoto Protocol has been in force in the United States since 2012.• In 1997, many United Nations countries agreed to reduce greenhouse gases.• To track progress, an emphasis was placed on improvement methods and emissions data.• The agreement would only slightly lower climate change impacts but it was seen as a start.
