Front

What is urban land cover?

Back

Urban land cover refers to areas of land that are developed for residential, commercial, industrial, and other human activities, which typically have significant impervious surfaces that prevent stormwater absorption.

Front

True or False: Urban land covers are areas of land with little to no amounts of stormwater runoff.

Back

False

Front

What is the purpose of storm drains in city streets?

Back

Storm drains are designed to prevent flooding during rain by directing stormwater away from streets and into drainage systems.

Front

Why is it important to prevent pollution from washing down storm drains?

Back

Because water that goes down storm drains is not cleaned or filtered; it goes directly into our creeks, potentially harming aquatic ecosystems.

Front

What process involves water seeping into the ground and replenishing aquifers?

Back

Infiltration.

Front

How do fertilizers typically enter water bodies?

Back

Fertilizers enter water bodies primarily through runoff, especially after rainfall.

Front

What is nonpoint source pollution?

Back

Nonpoint source pollution is pollution that comes from multiple sources rather than a single, specific site, making it harder to control.

Front

What is the difference between point source and nonpoint source pollution?

Back

Point source pollution comes from a single, identifiable source, while nonpoint source pollution comes from diffuse sources.

Front

What is the role of aquifers in the water cycle?

Back

Aquifers store groundwater and can supply water to wells and springs, playing a crucial role in the water cycle.

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.
