Write a note an shale gas. Explain the environment impact of shale gas.

Explanation

Shale refers to the soft finely stratified sedimentary rock that is formed from the compaction of small old rocks containing mud and minerals - such as quartz and calcite, trapped beneath earth.s surface. These rocks contain fossil fuels like oil and gas in their Pores.
The fuel is extracted by a technique called hydraulic fracturing (drilling or well boring of sedimentary tocks layers to reach productive reservoir layers).
Environmental concerns of shale gas:
(i) Shale drilling could affect groundwater reserves, which can contaminate the drinking water resources and also affect the fertility of the soil.
(ii) Million gallons of water is needed to break and release the shale gas, which inturn can affect the water table,
