What impact on human health would these countries experience if they adopt air quality regulations similar to the Americas? - The amount of exposure to outdoor and indoor air pollution would remain unchanged. - The number of premature deaths related to ultrafine particulate exposure would increase. - People would experience a decrease in negative health effects associated with air pollution. - Effects from impaired breathing would only decrease for those exposed to outdoor air pollution.

People would experience a decrease in negative health effects associated with air pollution.

Check each statement that applies to the atmosphere as a natural resource. Select three options. - The atmosphere interacts with the hydrosphere to redistribute water over the surface of Earth. - The atmosphere interacts with several Earth spheres, including the lithosphere. - Wind from the atmosphere creates ocean waves and currents. - The atmosphere causes plants to give off nitrogen. - The atmosphere causes volcanoes to erupt.

- The atmosphere interacts with the hydrosphere to redistribute water over the surface of Earth. - The atmosphere interacts with several Earth spheres, including the lithosphere. - Wind from the atmosphere creates ocean waves and currents.

Which statements describe the effects of indoor pollution? Select two options. - Ultrafine particles cause poor health. - Nose hairs and mucus catch all the particles before they reach the lungs - Ultrafine particles are absorbed by the lungs when people breathe. - Ultrafine particles contribute to more than 20,000 deaths per year in the United States. - Most ultrafine particles can be seen with the unaided eye.

- Ultrafine particles cause poor health. - Ultrafine particles are absorbed by the lungs when people breathe.

Which is the best strategy for addressing polluted air? - Reduce the cost of chemicals used in industrial processes. - Study the effects of mold exposure on people who suffer from asthma. - Encourage people to continue burning fossil fuels as they drive vehicles. - Build industrial plants and facilities that release chemicals during processing.

Study the effects of mold exposure on people who suffer from asthma.

Which role do ultrafine particles play in dirty air? - They contribute to less than 13,000 premature deaths a year. - They can worsen symptoms for people with breathing difficulties. - They are easily removed from the air when people see them floating. - They are constantly filtered by the nose, which prevents lung absorption.

They can worsen symptoms for people with breathing difficulties.

What are one of the ways the atmosphere recycle gases through interactions with the biosphere ? - Through the usage of nitrogen and release oxygen into the atmosphere from plants. - Though the process photosynthesis - Through available sunlight and release oxygen into the atmosphere. - The mineral content in the ground that plants rely on and release carbon dioxide into the atmosphere.

Though the process photosynthesis

Which statement describes indoor air pollution? - Smog is a common source of indoor air pollution. - Ultrafine particles are classified as indoor air pollutants. - Indoor air pollution does not affect symptoms for people with asthma. - Chemicals from industrial power plants cause indoor air pollution.

Ultrafine particles are classified as indoor air pollutants.

Which gas do plants absorb from the atmosphere during photosynthesis? sulfur oxygen nitric oxide carbon dioxide

carbon dioxide

Which correctly lists the three gases that are part of Earth's cycles in both the atmosphere and biosphere? radon, carbon monoxide, oxygen carbon dioxide, nitrogen, oxygen nitrogen, carbon dioxide, carbon monoxide carbon dioxide, radon, oxygen

carbon dioxide, nitrogen, oxygen

What was the order of steps taken by the United States to clean the air? enact the Clean Air Act, establish funding to study how to clean the air, create the EPA, and find cost-effective ways to keep the air clean establish funding to study how to clean the air, enact the Clean Air Act, create the EPA, and find cost-effective ways to keep the air clean find cost-effective ways to keep the air clean, establish funding to study how to clean the air, create the EPA, and enact the Clean Air Act create the EPA, enact the Clean Air Act, find cost-effective ways to keep the air clean, and establish funding to study how to clean the air

enact the Clean Air Act, establish funding to study how to clean the air, create the EPA, and find cost-effective ways to keep the air clean
