Answer:
20.) how water, solar and geothermal generate electricity
Explanation:
WATER- Once water is released, gravity takes over and the water flows downward through a turbine. As the blades of the turbine spin, they power a generator. ... As this water flows back down to the lower reservoir, it turns a turbine to generate more electricity.
SOLAR- When photons hit a solar cell, they. knock electrons loose from their atoms. If conductors are attached to the positive and negative sides of a cell, it forms an electrical circuit. When electrons flow through such a circuit, they generate electricity.
GEOTHERMAL - Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. The steam rotates a turbine that activates a generator, which produces electricity.
