Hace 1 día · If countries cut greenhouse gas emissions significantly (lowest trace), sea level rise by 2100 will be limited to 0.3 to 0.6 meters (1–2 feet). However, in a worst-case scenario (top trace), sea levels could rise 5 meters (16 feet) by the year 2300.
Hace 1 día · In some places the Mid-Atlantic Ridge reaches above sea level to form islands. Iceland, which rises from its crest, is rent by an extension of the median rift valley.East and west of the ridge, about 12,000 to 18,000 feet (3,700 to 5,500 metres) below sea level, lie basins that seem to present a relatively even profile, but parts of the basin floor are as mountainous as the Mid-Atlantic Ridge ...
Hace 2 días · The mean depth of the Pacific (excluding adjacent seas) is 14,040 feet (4,280 metres), and its greatest known depth is 36,201 feet (11,034 metres)—in the Mariana Trench —also the greatest depth found in any ocean. In the Northern Hemisphere the Pacific Ocean meets the Arctic Ocean in the Bering Sea. In the Southern Hemisphere the Pacific ...
Hace 1 día · The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions.It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.. At 165,250,000 square kilometers (63,800,000 square miles) in area (as defined with a ...
Hace 17 horas · One dramatic consequence of this warming is an increase in sea levels across the globe. The ocean absorbs 90% of the excess heat released into the atmosphere, and as water heats up it expands. Warming ocean temperatures now account for 40% of the global rise in sea levels, and the rate of rising has doubled over the past 30 years totalling 9cm.
Hace 5 días · One such area is the U.S. East Coast, where the combination of land subsidence and changes in ocean currents are expected to cause sea levels to rise up to 30% above the global average. Similarly, low-lying regions of Southeast Asia, such as Vietnam and Thailand, are bracing for sea levels to rise faster than elsewhere due to a complex ...
