The vertical motion of water in the ocean by which subsurface water of lower temperature and greater density moves toward the surface of the ocean. Upwelling occurs most commonly among the western coastlines of continents, but may occur anywhere in the ocean. Upwelling results when winds blowing nearly parallel to a continental coastline transport the light surface water away from the coast. Subsurface water of greater density and lower temperature replaces the surface water, and exerts a considerable influence on the weather of coastal regions. Carbon dioxide is transferred to the atmosphere in regions of upwelling. This is especially important in the Pacific equatorial regions, where 1-2 GtC/year may be released to the atmosphere. Upwelling also results in increased ocean productivity by transporting nutrient-rich waters to the surface layer of the ocean.

The warm ocean current flowing southward along the Brazilian coast. Its origin is in the westward flowing south equatorial current , part of which turns south and flows along the South American coast as the Brazil current, a tongue of water of high temperature and high salinity. At about 35=AE$=AFS it meets the Falkland (Malvinas) current , the two turning east and crossing the ocean as the South Atlantic current .

The warm, eastward-flowing ocean current that represents the direct continuation of the Kuroshio (in latitude 35 degrees where the Kuroshio leaves the coast of Japan), and flows eastward in two branches. The major branch of the Kuroshio extension turns due east; it retains its character as a well-defined flow approximately as far as longitude 160=AE$=AFE (eventually becoming the North Pacific current). The minor branch, to the north, continues toward the northeast as far as latitude 40=AE$=AFN where it bends east (eventually becoming the Aleutian current ). This northern branch becomes rapidly mixed with the cold waters of the Oyashio .

The water current flow within a large area.
Industry:Earth science
The zone around the continents extending from the low-water mark seaward to where there is a marked increase in slope to greater depths.
Industry:Earth science
The zone that includes both the continental shelf or continental borderland and the continental slope .

These are rocks within the Earth’s crust which have been altered by heat, pressure or chemically active fluids.

This is a derived formula, from the German physicist Max Planck that portrays the amount of radiation emitted by a blackbody as theoretically determined by its temperature. It is an equation that produces a curve, termed Planck's blackbody radiation curve that illustrates that the warmer a body is, the greater is its blackbody emission at each wavelength and the shorter is the wavelength of which emissions peak.

This is the collective term for sand, gravel and crushed rock. They can be compacted to firmly fill a space and are often bound together with cement (to make concrete) or bitumen (for road surfacing).
