Watershed Health and Pollution Impact

The video explains what a watershed is, describing it as an area where all water drains into a larger body of water. It discusses the difference between pervious and impervious surfaces, highlighting how they affect water absorption and runoff. The impact of storm water is covered, emphasizing how it can lead to pollution and flooding. The video concludes with solutions to prevent these issues, such as reducing impervious surfaces and community actions to maintain a healthy watershed.

What is a watershed?

• A type of water filter

• An area where all water drains into a larger body of water

• A type of ocean current

• A method of water purification

Which of the following is a pervious surface?

• Concrete

• Asphalt

• Grass

• Glass

What happens when rain falls on an impervious surface?

• It evaporates immediately

• It soaks into the ground

• It runs off, potentially causing pollution

• It turns into steam

What is stormwater?

• Water that is used for irrigation

• Water that is stored in reservoirs

• Water that runs off impervious surfaces during storms

• Water that is purified during storms

How can stormwater affect rivers?

• It can clean the river

• It can cause the river to dry up

• It can increase fish population

• It can carry pollution and cause flooding

What is the role of impervious surfaces in flooding?

• They prevent flooding

• They absorb excess water

• They contribute to flooding by preventing water absorption

• They have no impact on flooding

What is one way to prevent pollution in watersheds?

• Planting more trees

• Using more plastic

• Building more roads

• Increasing car usage

What is a bio swell?

• A method to allow water to soak into the ground

• A type of storm

• A type of plant

• A type of ocean wave

Why is it important to keep watersheds healthy?

• To create more impervious surfaces

• To reduce the number of storms

• To ensure clean water for humans and wildlife

• To increase property values

What can individuals do to help maintain healthy watersheds?

• Pick up after pets and reduce waste

• Litter more often

• Use more water

• Build more impervious surfaces
