Erosion And Air Pollution Test Review

Explanation
Car exhaust is the only one that causes air pollution here.

Explanation
After it rains, water can evaporate, meaning it turns into vapor and goes back into the atmosphere. It can also absorb into the ground, meaning it seeps into the soil and becomes groundwater. Additionally, water can run off into streams and rivers, meaning it flows over the surface and collects in bodies of water. These are the three possible outcomes for water after rainfall.

Explanation
Carpooling with several people is a way to help improve air quality because it reduces the number of vehicles on the road, which in turn reduces the amount of air pollution emitted from those vehicles. By sharing a ride with others, there are fewer cars on the road, leading to less traffic congestion and lower emissions of greenhouse gases and pollutants. This helps to improve air quality and reduce the negative impact of transportation on the environment.

Explanation
Acid rain is formed when pollutants such as sulfur dioxide and nitrogen oxide react with water vapor in the atmosphere. When acid rain falls, it can cause damage to buildings and statues by reacting with stone and metal, leading to chemical weathering. Acid rain can also cause damage to automobiles by corroding the metal surfaces and causing rust. However, the statement that acid rain causes toxic fumes to be released into the atmosphere is incorrect. Acid rain itself is not a source of toxic fumes, but rather a result of air pollution.

Explanation
Cleaning supplies, pet hair, and tobacco smoke are all examples of indoor air pollution. Cleaning supplies can release harmful chemicals into the air, such as volatile organic compounds (VOCs), which can contribute to respiratory problems and other health issues. Pet hair can contain allergens, such as pet dander, which can trigger allergies and asthma symptoms in sensitive individuals. Tobacco smoke is a well-known indoor air pollutant, containing numerous harmful chemicals that can cause respiratory and cardiovascular problems. These examples highlight the importance of maintaining good indoor air quality for the health and well-being of occupants.

Explanation
Ozone is a common pollutant that causes health problems for humans. It is created when exhaust pollutants react with sunlight. Sunlight plays a crucial role in the formation of ozone as it triggers a series of chemical reactions that convert exhaust pollutants into ozone molecules. This process occurs in the presence of nitrogen and other pollutants found in the atmosphere. Therefore, sunlight is the key factor in the creation of ozone and its harmful effects on human health.

Explanation
Remember that vegetation means plant growth of all types.
