Explain how the energy of flowing water is related to solar energy.

The energy of flowing water is an indirect source of solar energy. The heat of solar energy evaporates water from the oceans and the surface of earth. The water vapour thus formed rise high in the atmosphere, get cooled and fall back to the earth in the form of rain and snow. This rain water and the water formed by the melting of snow then flows rapidly in the rivers and provides us energy.
