Sinking

Sinking
Controlling oil spills by using an agent to trap the oil and sink it to the bottom of the body of water where the agent and the oil are biodegraded.

The process of sinking of a substance sinking in water. This occurs when the substance does not dissolve in water and its density is larger than that of water.
Sewage
Waste fluid in a sewer system.

Subsidence
Sinking or settling of soils so that the surface is disrupted, creating a shallow hole.

Subsidence: The sinking or lowering of the land's surface relative to average sea-level. This can be caused by a number of factors. On the Atlantic coast it is mostly caused by post-glacial rebound.

Subsidence: Sinking down of part of the earth's crust due to underground excavation, such as removal groundwater.

Subsidence. Sinking of the land surface due to a number of factors, of which groundwater extraction is one.

downwelling The process of accumulation and sinking of warm surface waters along a coastline. A change of air flow of the atmosphere can result in the sinking or downwelling of warm surface water.

OPENCAST MINING This is a type of mining where, instead of sinking a shaft and mining underground, the topsoil is stripped away from the surface and materials are mined from an open pit or trench.

In some places, the land is rising or sinking because of plate tectonics—the same forces that cause earthquakes, create volcanoes, and build mountain ranges.

The rising of warm air and the sinking of cool air. When a layer of air receives enough heat from the Earth's surface, it expands and moves upward. Colder, heavier air flows under it which is then warmed, expands and rises.

We are different because we don't see our role as simply sinking one more well in one more village, but also as finding ways to multiply our efforts by playing a leading role in the international water supply space.

Such areas often feature sinkholes, caverns, and sinking or disappearing creeks. In Virginia, this generally includes all that area west of the Blue Ridge and, in Southwest Virginia, east of the Cumberland Plateau.

The water is cleaned as it slowly travels downward and eventually reaches an underground aquifer. The purpose of man-made percolation ponds is both to clean the water and to keep the ground from sinking.

Other sources of exposure include the dumping of nuclear waste, the sinking of nuclear submarines, nuclear accidents such as Chernobyl and the discharges from nuclear waste processing plants in Europe.
