Watershed

What is nonpoint source water pollution?

• Water pollution that comes from a single identifiable source.

• Water pollution that is caused by industrial waste discharge.

• Water pollution that comes from multiple sources and is often caused by runoff from land, such as agricultural fields or urban areas.

• Water pollution that is solely due to sewage treatment plants.

What is an aquifer?

• A type of fish found in freshwater lakes.

• A geological formation that can store and transmit water, often tapped for drinking water.

• A machine used for drilling wells.

• A type of plant that grows in wetland areas.

What is the role of vegetation in a watershed?

• Vegetation helps to filter pollutants, stabilize soil, and maintain the water cycle within a watershed.

• Vegetation primarily serves as a habitat for wildlife.

• Vegetation is mainly responsible for increasing water temperature.

• Vegetation has no significant impact on the watershed.

What is the significance of wetlands in a watershed?

• They are primarily used for recreational activities.

• They act as natural filters, absorbing excess nutrients and pollutants, and providing habitat for wildlife.

• They are areas that are always dry and do not support any vegetation.

• They are only important for flood control.

What is the difference between surface water and groundwater?

• Surface water is found in lakes, rivers, and streams, while groundwater is found beneath the earth's surface.

• Surface water is always cleaner than groundwater.

• Groundwater is found in lakes, rivers, and streams, while surface water is found beneath the earth's surface.

• Surface water is only found in oceans, while groundwater is found in all other places.

How do trees affect watersheds?

• They increase soil erosion and runoff.

• They help to absorb rainfall, reduce runoff, and prevent soil erosion, thus protecting watersheds.

• They have no significant impact on watersheds.

• They only provide shade and habitat for wildlife.

What is the impact of urbanization on watersheds?

• Urbanization can increase runoff, reduce natural filtration, and lead to more pollution entering water bodies.

• Urbanization has no significant effect on watersheds.

• Urbanization improves water quality by reducing runoff.

• Urbanization decreases the amount of impervious surfaces in watersheds.

What is groundwater?

• Water found in rivers and lakes.

• Water located below the surface of the land.

• Water vapor in the atmosphere.

• Water that is used for irrigation.

What is point source water pollution?

• Contamination that comes from multiple sources, such as runoff from fields.

• Contamination that comes from a single, identifiable source, such as a pipe or a drain.

• Contamination that occurs naturally in water bodies without human intervention.

• Contamination that is caused by atmospheric deposition, such as acid rain.

What human activity is least likely to affect watersheds?

• Cutting down trees

• Fertilizing lawns

• Reading a book

• Paving roads
