The gravitational pull of the moon causes the sea-water to rise periodically.
(a) What name is given to the condition of the sea when its water is raised?
(b) What name is given to the condition of the sea when its raised water recedes?
(c) What name is given to the energy which can be harnessed from this natural phenomenon?
(d) Draw labelled diagram to show how this energy can be harnessed to generate electricity.
(a) The condition when the sea water rises is termed as high tide.
(b)When the rised water of the sea resides, the situation is termed as low tide.
(c)Tidal Energy (Tidal energy is a form of hydropower that converts the energy obtained from tides into useful forms of power, mainly electricity)
(d)At high tide, water flows from sea into reservoir and turns the turbine.
At low tide, stored water flows out from reservoir into sea and turns the turbine.
