AP®︎ Environmental Science: Topic 6.9 Flashcards

Renewable electricity generation in which moving water turns a turbine connected to a generator, without burning fuel

A dam stores elevated water in a reservoir and releases it through turbines to generate electricity

The vertical elevation difference through which water falls in a hydroelectric system; greater head generally permits greater power output

Hydroelectric generation that uses or diverts a river’s natural flow with little or no water storage

Renewable energy from rising, falling, or flowing tides used to turn turbines

A barrier across an estuary or bay that directs water through turbines as the tide rises or falls

Loss of river connectivity when a dam blocks organism movement, especially migration between feeding and spawning habitats

The settling of river sediment in a reservoir, reducing storage capacity and depriving downstream ecosystems of sediment and nutrients
