GK questions on rivers of the world general knowledge trivia quiz in English printable free river quizzes test are full of useful and interesting facts and stats about various rivers. Precipitation, direct overland flow, springs and seepages, and meltwater at the borders of snowfields and glaciers all feed rivers. Direct precipitation on the water surface has a minor impact unless a large portion of a watershed is covered by lakes, GK questions on rivers of the world. Seepage and percolation into shallow or deep aquifers (porous rock layers that readily convey water) as well as evaporation cause river water losses. Surface discharge or streamflow is sustained by the differential between water intake and loss.
The quantity of water in river systems at any given moment is a minuscule percentage of the overall amount of water on the planet; the oceans hold 97 percent of all water, and around three-quarters of freshwater is stored as land ice; GK questions on rivers of the world, virtually all of the rest is groundwater. Lakes retain less than 0.5 percent of all freshwater, soil moisture approximately 0.05 percent, and water in river channels about half that, 0.025 percent, or about one four-thousandth of the total fresh water on the planet.
Water, on the other hand, is continually cycling via land ice, soil, lakes, groundwater (in part), and river channels. The discharge of rivers into the seas provides these systems with the equivalent of water vapor that is blown overland and subsequently precipitated as rain or snow—roughly 7% of global annual precipitation and 30% of precipitation on land regions, GK questions on rivers of the world. Rivers transport rock debris to the sea 100 times more effectively than coastal erosion. Their sediment delivery rate is comparable to a 30 centimeter (12 inches) average lowering of the land in 9,000 years, which is enough to erase all of the present continental relief in 25,000,000 years.
Rock pieces eroded from rocky channels or dissolved rock debris enter river systems. The solid particles suffer regular size and form changes as they flow downstream as bed load or suspension load, GK questions on rivers of the world. Except in high latitudes and along steep slopes, little or no coarse bedload ever makes it to the sea. Because the streamflow is irregular and the transported material is prone to entering temporary storage, movement of the solid load down a river valley is irregular, resulting in distinctive river-built features such as riffles, midstream bars, point bars, floodplains, levees, alluvial fans, and river terraces.
The Ganges-Brahmaputra and Huang He (Yellow River), which together deliver around 4,500,000,000 tons a year, are believed to supply almost a quarter of all suspended load; the Yangtze (Chang Jiang), Indus, Amazon, and Mississippi deliver between 500,000,000 and 350,000,000 tons a year, GK questions on rivers of the world. Suspended sediment movement on the Huang He results in a denudation rate of around 3,090 tons per square kilometer (8,000 tons per square mile) per year; the Ganges-Brahmaputra denudation rate is about half that. For certain smaller rivers, unusually high rates have been recorded: The Jing, for example, produces 1,060 tons per square kilometer per year, while the Luo produces 1,080 tons per square kilometer per year. Both are Loess Plateau tributaries of the Huang He, GK questions on rivers of the world.
Rivers in medieval Europe provided the water that kept towns afloat and the sewers that took away trash, and they were commonly employed as power sources, either directly or by offtakes, GK questions on rivers of the world. Three of these, Vienna, Budapest, and Belgrade, are on the Danube, with two more, Sofia and Bucharest, on feeder streams above stem floodplain level, according to Western European history.
As may be observed in the United Kingdom, France, and Germany, the placement of provincial and equivalent capitals is much more firmly linked to riparian locations. Natural rivers dictated the routes of discovery, conquest, and settlement in modern history in both North America and northern Asia, GK questions rivers of the world. Portaging along lines defined by transient ice-marginal or ice-diverted channels permitted transit from one river system to the next in these places. Natural streams, particularly in Ohio, were used by many pioneer immigrants from the interior of North America.
