Flashcard: Watershed Project Content Topics

Front

What are wetlands?

Back

Wetlands are areas where water covers the soil, either permanently or seasonally, and they play a crucial role in water storage, flood control, and providing habitat for wildlife.

Front

How do wetlands affect flooding?

Back

Wetlands temporarily store water and release it over time, thus slowing erosion and downstream flooding.

Front

What is groundwater?

Back

Groundwater is water that is found underground in soil and rock layers, and it can flow into streams and rivers.

Front

How do wetlands improve water quality?

Back

Wetlands slow down water flow, allowing sediments and pollutants to settle out before the water moves downstream.

Front

What are nitrates?

Back

Nitrates are nutrients that are essential for plant growth but can be harmful in excessive amounts in waterways.

Front

What causes dead zones in water bodies?

Back

Dead zones are primarily caused by excessive nutrient pollution from human activities, leading to low oxygen levels.

Front

What role do plants play in wetlands?

Back

Plants in wetlands help filter pollutants, stabilize soil, and provide habitat for various species.

Front

What is the significance of floodplains?

Back

Floodplains are areas adjacent to rivers that are prone to flooding and play a vital role in absorbing excess water and reducing flood risk.

Front

How does urbanization affect watersheds?

Back

Urbanization can increase runoff and pollution, leading to degraded water quality and altered natural water flow.

Front

What is the impact of agricultural runoff on water bodies?

Back

Agricultural runoff can introduce excess nutrients and pollutants into water bodies, leading to eutrophication and dead zones.
