Definitions:

Acid Deposition

The falling of acids and acid-forming compounds from the atmosphere to the earth's surface, often resulting in environmental harm.

Eutrophication

The process by which a body of water becomes excessively enriched with nutrients, leading to plant growth that depletes oxygen in the water, affecting fish and other wildlife.

Cultural Eutrophication

The process by which a body of water becomes enriched in dissolved nutrients (like phosphates) from human activity, leading to excessive plant growth and decay that depletes oxygen, harming water quality and aquatic life.

Great Lake

Each of the five large, interconnected freshwater lakes located in North America on the Canada-United States border, constituting the largest group of freshwater lakes by total area.
