What is the most effective approach the government can take to keep the air clean? create and enforce regulations that limit fossil fuel burning by industries use funds to understand why smoke and mold are causes of outdoor air pollutants educate people about the threats to outdoor clean air from visible forms of air pollution modify regulations under the Clean Air Act by including expensive options to reduce air pollution

create and enforce regulations that limit fossil fuel burning by industries

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

Which factor is a major contributor to outdoor air pollution? radon fossil fuels ultrafine particles carbon monoxide

fossil fuels

Study the image of a plant. Photosynthesis. An arrow points from the sun to the plant. An arrow points from water in the soil to roots. An arrow points from soil in the roots. An arrow points from leaves to the small clouds. Which gas is cycled into the atmosphere at the arrow? oxygen nitrogen water vapor carbon dioxide

oxygen

What impact does the atmosphere have on the Earth's cycles? Select four options. produces wind currents transfers nitrogen from air to soil transfers water into Earth's oceans moves oxygen from volcanic eruptions for plants moves oxygen and carbon dioxide through the biosphere

produces wind currents transfers nitrogen from air to soil transfers water into Earth's oceans moves oxygen and carbon dioxide through the biosphere

Which health effects are associated with exposure to indoor air pollution? Select three options. stroke asthma diabetes skin cancer heart attack

stroke asthma heart attack

What happens when the atmosphere interacts with the biosphere? Select two options. Winds are produced. Groundwater supplies are replenished. Carbon dioxide is cycled during plant respiration. Water vapor is available for plant photosynthesis. Volcano eruption influences the cycling of nitrogen.

Carbon dioxide is cycled during plant respiration. Water vapor is available for plant photosynthesis.

Which interaction between the atmosphere and biosphere takes place during plant respiration? Plants use nitrogen and release oxygen into the atmosphere. Plants use oxygen and release carbon dioxide into the atmosphere Plants rely on available sunlight and release oxygen into the atmosphere. Plants rely on mineral content in the ground and release carbon dioxide into the atmosphere.

Plants use oxygen and release carbon dioxide into the atmosphere

What happens when the threat of exposure to dirty air is reduced in a community? There is enough oxygen available for people's lungs to function normally. The amount of indoor air pollutants released during a fossil fuel burn decreases. There is a minimal exposure risk to the outdoor dirty air pollutants, carbon monoxide and radon. The risk of experiencing digestive related diseases from exposure to a buildup of dirty air is low.

There is enough oxygen available for people's lungs to function normally.

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

carbon dioxide
