Physiography Relief The Pacific basin may conveniently be divided into three major physiographic regions: Eastern region The eastern Pacific region, which extends southward from Alaska to Tierra del Fuego, is relatively narrow and is associated with the American cordilleran system of almost unbroken mountain chains, the coastal ranges of which rise steeply from the western shores of North and South America.

The continental shelf, which runs parallel to it, is narrow, while the adjacent continental slope is very steep. Its structure is more complex than that of the eastern region. Characteristically associated with the ocean trenches of the western region are festoons of either peninsulas or islands or both.

The islands, which include those of Japan as well as numerous smaller islands, represent the upper parts of mountain systems that rise abruptly from the deep ocean floor. The island clusters of the western Pacific form the boundaries of the several wide and deep continental seas of the region.

Aerial view of rock islands, Palau. The submerged parts of the series of ridges that are capped by the island archipelagoes of the western Pacific are continuous and are to be found at depths of less than about 2, feet metres.

These ridges include the Aleutian Ridge in the northwestern Pacific; the series of ridges extending southward through the KurilBoninand Mariana island groups, and the archipelagoes of Yap and Palau ; those extending eastward from New Guineaincluding the Bismarck Archipelago and the Solomon and Santa Cruz island chains; and, finally, the ridges extending southward, from which rise the SamoaTongaKermadecand Chatham island groups, as well as Macquarie Island. Bottom deposits Apart from the narrow coastal zone of the eastern region and the broad continental seas of the western region, the Pacific is floored with pelagic oceanic material derived from the remains of marine plants and animals that once inhabited the waters lying above.

Calcareous globigerina ooze occurs in the shallower parts of the South Pacific, the dissolving power of the seawater at great depths being sufficient to dissolve calcareous material to such an extent that these oozes are not generally found at depths in excess of about 15, feet 4, metres.

Silica-containing material, such as radiolarian and diatom ooze, is found at greater depths, but even these siliceous remains are dissolved at very great depths, where the characteristic deposit is red clay. Red clay, which covers no less than half of the Pacific floor, is believed to be formed of colloidal extremely finely divided clays derived essentially from the land.

Manganese nodules on the southern Pacific Ocean floor. Courtesy of the Lamont-Doherty Geological Observatory, Columbia University On the abyssal plainswhere sediments accumulate slowly, chemical and biological processes lead to the formation of metal-bearing coatings around objects such as the ear bones of fishes.

The nodules so formed contain manganese, iron, nickel, copper, cobalt, and traces of other metals such as platinum. They cover large areas of the ocean floor in the Pacific.

Similar processes form coatings, called manganese crusts, on the rock surfaces of seamounts. Among the many different forms of land-derived muds formed by the erosive action of rivers, tides, and currents that floor the continental shelves and slopes of the Pacific, the yellow mud of the Yellow Sea is of particular interest. The mud is conveyed to the seabed by the Huang He, which drains a vast area of northern China blanketed with loessa fine-grained soil.

Geologically, they consist partly of sedimentary rocksand their structures are similar to those of the coastal mountain ranges of the adjacent continent. In the northern and western Pacific the Andesite Line follows close to seaward the trend of the island arcs from the Aleutians southward to the Yap and Palau arcs, thence eastward through the Bismarck, Solomon, and Santa Cruz archipelagoes, and thence southward through the Samoa, Tonga, and Chatham groups and Macquarie Island to Antarctica.

Islands to the west of the line are rich in andesitea type of intrusive igneous rock; islands to the east oceanic side of it are essentially of basaltan extrusive igneous rock.

Oh no, there's been an error

The numerous oceanic islands of the Pacific are unevenly distributed. They lie, in the main, between the Tropics of Cancer and Capricorn and occur in great numbers in the western Pacific. The northernmost chain of oceanic islands is associated with the Hawaiian Ridge. The Hawaiian archipelago consists of about 2, islands, although the term Hawaiian Islands is usually applied to the small group that lies at the eastern end of the archipelago.

To the south of Micronesia lies Melanesiawhich consists mostly of small coral islands. Geology Evidence drawn from various geophysical fields— seismologyvolcanologygravimetry, and paleomagnetism remanent magnetism —points to the general validity of the theory of plate tectonics.

All the major physical features in the Pacific are understood to originate in plate tectonics. The western Pacific arcs of volcanic islands and deep trenches are convergent zones where two plates are colliding, one being subducted forced under the other. The East Pacific Rise is an active spreading centre where new crust is being created. The northeastern Pacific margin is the strike-slip zone where the American Plate and the Pacific Plate are gliding laterally past each other via the major San Andreas Fault system.

The floor of the northeastern Pacific is remarkable for its several major fracture zoneswhich extend east and west and which, in some instances, are identifiable over distances of thousands of miles. Of great geologic interest are the seamounts submerged volcanoesguyots flat-topped seamountsand oceanic islands of the Pacific. The numerous tropical islands of the Pacific are mainly coralline. The principal types of coral reefs — fringingbarrierand atoll —as well as the guyots, which rise within the Pacific from the ocean floor in latitudes north and south of the tropics, are explained partially by the slow subsidence theory advanced by the English naturalist Charles Darwin during the 19th century and partially by the theory of plate tectonics.

Climate The wind and pressure systems of the Pacific conform closely to the planetary system—the patterns of air pressure and the consequent wind patterns that develop in the atmosphere of the Earth as a result of its rotation Coriolis force and the inclination of its axis ecliptic toward the Sun.

This clearer, better-quality video published online in July shows exactly the same scene. Entitled, "When the river meets the ocean," it indicates that it was taken on the Fraser River in British Columbia in Canada.

Maryan Pearson, who posted the video, says she took it when she was aboard a ferry between Duke Point and Vancouver. What explains the strange sight? This case is similar to a photo published in that claimed to show the exact spot where the Pacific and the Atlantic meet. The photo was actually taken in by Ken Bruland, a researcher at the University of California, Santa Cruz, who was studying the phenomenon in the Gulf of Alaska. He explained why it happened in an article by the debunking website Snopes.
