The oil and gas industry and trade groups are quick to point out that chemicals typically make up just 0.5 and 2.0% of the total volume of the fracturing fluid. When millions of gallons of water are being used, however, the amount of chemicals per fracking operation is very large.
How deep can an ocean get? Real Deep ;) Actually, it can get to 35,838 feet. That's how deep Challenger Deep in the Marianas Trench off the Marianas Island in the Pacific Ocean gets. The U.S. Navy su â¦ bmersible Trieste reached it in 1960. That's about a mile deeper than Mount Everest is high. And that's real deep.
The deep sea is often described as beginning at the edge of the continental shelf. The depth of the continental shelf varies around the world, but on average it is around 200 m. This coincides with the average depth of the bottom of the euphotic zone, which means that the deep sea is also a dark sea. The average depth of the sea is around 4,000 m (almost 2.5 miles) and the deepest point in the Mariana Trench is about 11,000 m, so there is a lot of deep sea around the world! In fact, about 90 % of the worldâs ocean is deep sea.
