EFFECTS OF OVER UTILIZATION GROUND WATER
flood is an overflow of water that submerges land that is usually dry. Floods can also occur in rivers when the flow rate exceeds the capacity of the river channel
CLASSIFICATION OF FLOODS�
Drought is an event of prolonged shortages in the water supply, whether atmospheric, surface water or ground water
Dam is a barrier that stops or restricts the flow of water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture
7 largest dams in India.
Dams are Modern Temples of India-Nehru
Tamil Nadu, Gujarat, Rajasthan, Telangana, Maharashtra and Madhya Pradesh are the top states of India with largest solar power generation facilities and solar parks.
In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy
According to the estimates of the Indian government, the country has a potential of 8,000 MW of tidal energy. This includes about 7,000 MW in the Gulf of Cambay in Gujarat, 1,200 MW in the Gulf of Kutch and 100 MW in the Genetic delta in the Sunder bans region of West Bengal
Tamil Nadu is the largest producer of Wind Energy followed by Maharashtra (4450.8 MW), Gujarat (3645.4 MW), and Rajasthan (3307.2 MW)
There are four major types of nonrenewable resources: oil, natural gas, coal, and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels. Fossil fuels were formed within the Earth from dead plants and animals over millions of years
Coal
Coal is a black or brownish rock. We burn coal to create energy. Coal is ranked depending on how much “carbonization”. Carbonization is the process that ancient organisms undergo to become coal.
Petroleum
Petroleum is a liquid fossil fuel. It is also called oil or crude oil.
Petroleum is trapped by underground rock formations. In some places, oil bubbles right out of the ground

Natural Gas
Natural gas is another fossil fuel that is trapped underground in reservoirs. It is mostly made up of methane. The decomposing material in landfills also release methane, which smells like rotten eggs.
Nuclear energy harvests the powerful energy in the nucleus, or core, of an atom. Nuclear energy is released through nuclear fission, the process where the nucleus of an atom splits. Nuclear power plants are complex machines that can control nuclear fission to produce electricity. The material most often used in nuclear power plants is the element uranium
