Description

behold the shooting nature waterfall at your android screen. awaterfall is a river flooding or other body of water's steep fallover a rocky ledge into a plunge pool below. waterfalls are alsocalled cascades. cliff and steep, drops and stream, nature. theprocess of erosion, the wearing away of earth, plays an importantpart in the formation of waterfalls. waterfalls themselves alsocontribute to erosion. get this live wallpapers of waterfalls andliquid live wallpapers now. often, waterfalls form as streams flowfrom soft rock to hard rock. this happens both laterally (as astream flows across the earth) and vertically (as the stream dropsin a waterfall). in both cases, the soft rock erodes, leaving ahard ledge over which the majestic stream falls. a fall line is theimaginary line along which parallel rivers plunge as they flow fromuplands to lowlands. many waterfalls in an area help geologists andhydrologists determine a region's fall line and underlying rockstructure. as a stream flows, it carries sediment. the sediment canbe microscopic silt, pebbles, or even boulders. sediment can erodestream beds made of soft rock, such as sandstone or limestone.eventually, the stream's channel cuts so deep into the stream bedthat only a harder rock, such as granite, remains. waterfallsdevelop as these granite formations form cliffs and ledges. astream's velocity increases as it nears a waterfall, increasing theamount of erosion taking place. the stunning movement of water atthe top of a waterfall can erode rocks to be very flat and smooth.rushing water and sediment topple over the waterfall, eroding theplunge pool at the base. the crashing flow of the water may alsocreate powerful whirlpools that erode the rock of the plunge poolbeneath them. spring and water, autumn. the resulting erosion atthe base of a waterfall can be very dramatic, and cause thewaterfall to "recede." the area behind the waterfall wallpapers isworn away, creating a hollow, cave-like structure called a rockshelter. eventually, the rocky ledge (called the outcropping) maytumble down, sending boulders into the stream bed and plunge poolbelow. this causes the waterfall live wallpaper to recede manymeters upstream. the waterfall erosion process starts again,breaking down the boulders of the former outcropping. erosion isjust one process that can form waterfalls. a waterfall may formacross a fault during peak flow, or crack in the earth’s surface.an earthquake, landslide and glacier, or volcano may also disruptstream beds and help create waterfalls. features: hd graphic 720pcool animation
