Sink (geography)
An endorheic basin ( ; also endoreic basin and endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water (e.g. rivers and oceans); instead, the water drainage flows into permanent and seasonal lakes and swamps that equilibrate through evaporation. Endorheic basins are also called closed basins, terminal basins, and internal drainage systems. Endorheic regions contrast with open lakes (exorheic regions), where surface waters eventually drain into the ocean. In general, water basins with subsurface outflows that lead to the ocean are not considered endorheic; but cryptorheic. Endorheic basins constitute local base levels, defining a limit of the erosion and deposition processes of nearby areas. Endorheic water bodies include the Caspian Sea, which is the world's largest inland body of water. Etymology The term ''endorheic'' derives from the French word , which combines ( 'within') and 'flow'. Endorheic lakes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
37° N
Following are circles of latitude between the 35th parallel north and the 40th parallel north: 36th parallel north The 36th parallel north is a circle of latitude that is 36 degrees north of the Earth's equatorial plane. It crosses Africa, the Mediterranean Sea, Asia, the Pacific Ocean, North America and the Atlantic Ocean. In the ancient Mediterranean world, its role for navigation and geography was similar to that played by the Equator today. From 7 April 1991 to 31 December 1996, the parallel defined the limit of the northern no-fly zone in Iraq. At this latitude the sun is visible for 14 hours, 36 minutes during the summer solstice and 9 hours, 43 minutes during the winter solstice. United States In the United States, the 36th parallel north is occasionally used as a rough northern boundary for the Sun Belt, a region spanning most Southern and Southwestern states and comprising most of the nation's warmest climates.

Orography
Orography is the study of the topographic relief of mountains, and can more broadly include hills, and any part of a region's elevated terrain. Orography (also known as ''oreography'', ''orology,'' or ''oreology'') falls within the broader discipline of geomorphology. The term orography comes from the Greek: , hill, , to write. Uses Mountain ranges and elevated land masses have a major impact on global climate. For instance, the elevated areas of East Africa substantially determine the strength of the Indian monsoon.Srinivasan, J., Nanjundiah, Ravi S. and Chakraborty, Arindam (2005)"Impact of Orography on the Simulation of Monsoon Climate in a General Circulation Model" Indian Institute of Science. In scientific models, such as general circulation models, orography defines the lower boundary of the model over land. When a river's tributaries or settlements by the river are listed in 'orographic sequence', they are in order from the highest (nearest the source of the river) to t ...
