Hydropower can be harnessed from flowing and falling water. Water stored behind dams and at a height has a lot of potential energy which is converted into mechanical and electrical energy.This water is released gradually and is made to fall under the force of gravity and drive hydraulic turbines and electrical generators.
Hydropower is also another indirect form of using solar energy. Hydropower has great potential as a supplier of electricity but environmental constraints limit such a development as the generation of electricity by hydroelectric power plants result in pollution and massive ecological disruptions such as land flooding, siltation, eutrophication and adverse effects on flora and fauna.
Smaller dams and reservoirs cause less damage but cannot exploit the full potential of this energy resource. Planning environmental impact assessment and construction of a hydroelectric power plant takes many years and the high initial capital investments are also limiting factors in the development of hydropower.
The development cost of hydroelectric power plants can be reduced by developing low cost turbines and generators, involving public participation in the development and operation of the project and using efficient environmental friendly technologies.
Answer:
The answer is E.) Lithosphere, Asthenosphere.
Explanation:
Tectonic plates belong to the layer called Lithosphere. The tectonic plates float on the Asthenosphere which is below the Lithosphere and more fluid than the crust.
From the Earth's surface to the its center we can say that the inside of the Earth is divided into four layers which, starting from the top , are:
i) the crust
ii) the mantle, (Lithosphere, Asthenosphere , Mesosphere)
iii) the outer core
iv) the inner core.
The tectonic plates are part of the Lithosphere and are constantly moving even though the crust is fairly solid. This is because the inner layers
( Asthenosphere , Mesosphere) are much are fluid and are constantly moving which tends to move the tectonic plates. When the tectonic plates collide they do so with tremendous force which leads to earthquakes and sometimes tsunamis as well resulting in a loss of life and property.
