Sentences with phrase «ground at high pressure»

The 600 - plus - page report that resulted looks at a variety of ways fracking could have an effect on local drinking water: withdrawing millions of gallons of water needed to frack a well, improperly mixing chemicals with the water at the well, injecting that fracking fluid into the ground at high pressure to fracture rock as much as two miles beneath the surface, handling the contaminated water then produced by the well and finally improperly storing or disposing of that water.

Pressure is proportional to the square of the velocity, so the air pressure at top is four times as high as near thePressure is proportional to the square of the velocity, so the air pressure at top is four times as high as near thepressure at top is four times as high as near the ground.

InSAR uses a highly accurate radar to measure the change in distance between the satellite and ground surface, allowing the team to show that injecting water into the wells at high pressure caused ground uplift near the shallower wells, the release said.

While the large atmospheric pressure at the surface and the high altitude of the Venusian cloud layer appears to exclude the possibility of cloud - to - ground lightning (Gurnett et al. 2001; Aplin 2006), several authors have suggested that lightning discharges above, between or within clouds may occur (Borucki 1982; Russell & Scarf 1990; Gurnett et al. 2001).

The diffuser's role is to prevent the rear of the car from lifting and guarantee stability at high speed by channeling airflow in such a way that it increases ground effect by producing a low pressure zone beneath the car.

It's created through a high - pressure, high - temperature process called rendering: Fat and moisture are separated out from dried, solid protein by grinding everything up and steam cooking it all at extremely high temperatures.

Increased weed and pest pressure associated with longer growing seasons and warmer winters will be an increasingly important challenge; there are already examples of earlier arrival and increased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is increased.72

Because pressure decreases with height, we have arranged the graphs in this essay so that the lowest pressures (i.e., the stratosphere) are at the top and the highest pressures (i.e., ground level) are at the bottom.

The latter has precipitation falling from it and represents net dissipation of that part of the cloud with higher pressure at the ground than beneath the ascending section.

In 1939, Carl - Gustaf Arvid Rossby, a Swedish - born America meteorologist, discovered waves in the northern jet stream that were associated with the high and low pressure systems at ground level that form daily weather patterns.

Pressure ridges (2 - 4 + meters high above water, often miles long) were visible off shore at variable distance, defining the line where free circulating pack ice bumped up against grounded shore ice.

During fracking, on or offshore, chemical - laced water is injected at high pressure into shale formations below ground.
