What is the abyssal zone?
The tendency for a transition zone to have greater species diversity and a higher density of organisms than found in either of the individual ecosystems.
What is the edge effect?
Where a river meets the sea.
Surface water that flows into freshwater life zones such as lakes, ponds, inland wetlands, rivers, and streams.
What is runoff?
The deflection of a mass as it moves over a spinning surface.

What is permafrost?
Coastal land areas covered with water all or part of the year.
What are coastal wetlands?
The process by which lakes gain nutrients.
What is eutrophication?
These are the aquatic equivalents of terrestrial biomes.
What are aquatic life zones?
