Watershed & Oceans Review

Front

What is the relationship between ecosystem health and water quality?

Back

The health of an ecosystem is directly related to the quality of water; poor water quality can lead to a decline in ecosystem health.

Front

What is the effect of fertilizer runoff on aquatic ecosystems?

Back

Fertilizer runoff can lead to rapid algae growth, which can deplete oxygen in the water and harm aquatic life.

Front

Define runoff in the context of water movement on land.

Back

Runoff is all the water that runs off the surface of the land and washes into rivers, streams, and other waterways.

Front

Which human activity is least likely to affect watersheds?

Back

Reading a book is least likely to affect watersheds compared to activities like agriculture, urban development, or industrial processes.

Front

What are some resources we depend on the ocean for?

Back

We depend on the ocean for food, transportation, recreation, and climate regulation.

Front

What is a watershed?

Back

A watershed is an area of land where all the water that falls as precipitation drains into a common outlet, such as a river or lake.

Front

How does urbanization impact watersheds?

Back

Urbanization can increase runoff and pollution, reduce natural filtration, and alter the natural flow of water in watersheds.

Front

What is the role of wetlands in a watershed?

Back

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

Front

Explain the concept of point source pollution.

Back

Point source pollution refers to contaminants that enter a water body from a single, identifiable source, such as a pipe or a ditch.

Front

What is non-point source pollution?

Back

Non-point source pollution comes from multiple diffuse sources, such as agricultural runoff or urban stormwater, making it harder to control.
