River and Watershed Flashcard

Front

What is eutrophication?

Back

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

Front

What is a watershed?

Back

A watershed is an area of land that drains rainwater and snowmelt into a common body of water, such as a river, lake, or ocean.

Front

What are tributaries?

Back

Tributaries are smaller rivers or streams that flow into a larger river, contributing to its water flow.

Front

How does littering affect a watershed?

Back

Littering can harm a watershed by polluting the water, harming wildlife, and disrupting the ecosystem.

Front

What is an algal bloom?

Back

An algal bloom is a rapid increase in the population of algae in a water body, often due to excess nutrients, which can lead to eutrophication.

Front

What happens to oxygen levels during eutrophication?

Back

During eutrophication, oxygen levels in the water decrease due to the decomposition of dead algae, which consumes oxygen.

Front

What is the role of proper fertilizer use in preventing eutrophication?

Back

Proper fertilizer use helps prevent eutrophication by minimizing nutrient runoff into water bodies, reducing the risk of algal blooms.

Front

What are the signs of eutrophication in a body of water?

Back

Signs of eutrophication include excessive algae growth, decreased water clarity, and reduced oxygen levels.

Front

How do human activities impact watersheds?

Back

Human activities such as littering, urban development, and agriculture can negatively impact watersheds by increasing pollution and altering water flow.

Front

What is the importance of trees in a watershed?

Back

Trees help to stabilize soil, reduce erosion, and improve water quality by filtering pollutants.
