Major continental divides, showing drainage into the major oceans and seas of the world. Grey areas are endorheic basins that do not drain to the ocean.. A continental divide is a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not ...
The borders of the oceans are the limits of Earth's oceanic waters.The definition and number of oceans can vary depending on the adopted criteria. The principal divisions (in descending order of area) of the five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean.
The snow that falls on it (about 10 metres (33 ft) per year) does not actually flow downhill as water, but creeps downhill in the form of glacial ice. That ice flows down the Athabasca Glacier to the Arctic Ocean via the Athabasca and Mackenzie rivers. Ice flowing west goes to the Pacific Ocean via Bryce Creek and the Bush and Columbia Rivers.
This phenomenon is why rivers can still flow even during times of drought. [3] Rivers are also fed by the melting of snow glaciers present in higher elevation regions. [3] In summer months, higher temperatures melt snow and ice, causing additional water to flow into rivers. Glacier melt can supplement snow melt in times like the late summer ...
Most lakes are not actually endorheic, but endorheic basins may not have standing water, or have water only seasonally. The most significant endorheic basins are these: Great Basin covering most of Nevada, the western part of Utah, and smaller amounts of other U.S. states; Great Divide Basin on the Continental Divide in Wyoming; Guzmán Basin
The high marsh is located between the low marsh and the upland border and it usually only flooded when higher than usual tides are present. [53] The upland border is the freshwater edge of the marsh and is usually located at elevations slightly higher than the high marsh.
Based on this outdated definition, Dome Argus is the highest point in the East Antarctic ice sheet and could be considered a triple divide if it is assumed that the ice forms a watershed. ( 80°22′S 77°21′E / 80.367°S 77.350°E / -80.367; 77.350 ( Dome Argus
The centre of the water hemisphere is the antipode of the centre of the land hemisphere, and is therefore located at (near New Zealand's Bounty Islands in the Pacific Ocean An alternative assignment determines the centre of the land hemisphere to be at 47°24′42″N 2°37′15″W / 47.411667°N 2.620833°W / 47.411667; -2.620833 ...
