The diagram shows the steps involved in generating hydroelectric power.
Overall, the diagram illustrates a step-by-step procedure that follows a cyclical sequence. The process involves several physical and natural treatments, including cycling, collecting, transmitting, and storing.
First, the sun heats the ocean, causing water to evaporate. As the water vapor rises, it cools and turns into clouds that move over the land. Eventually, the clouds release rain, and some of the water collects in a reservoir. A dam holds the water in place and has a valve to control its flow. When the valve is opened, the water flows downhill with force, spinning a turbine to generate electricity. This electricity is then sent through high-voltage power lines to a transformer station, where it is adjusted to the right voltage for use in homes and businesses.
Finally, some of the extra electricity is used to pump water back into the reservoir, so it can be reused to produce electricity when needed.
