10 points how is natural gas harnessed from the marcellus shale?

 

The natural gas is harnessed from the Marcellus Shale by using the technique of hydraulic fracturing.

Explanation:

The Marcellus Shale is a sedimentary rock about 7,000 to 12,000 feet below the Earth's surface lying beneath the states of New York, West Virginia, Ohio and Pennsylvania. It is one of the world's richest deposits of natural gas. To extract the natural gas from this shale, the technique of hydraulic fracturing is used in which the Earth is drilled vertically and hydraulic agents like water and other chemicals are introduced into the Earth's surface at high pressure, forcing the gas to rise up to the surface.

Answer they are produced by collision of tectonic plates;
