"The Bible only refers to `` high hills `` , and the mountains today wre formed only towards the end of , and after , the Flood by collision of the tectonic plates and the associated upthrusting . In support of this , the layers that form the uppermost parts of Mt Everest themselves of fossil-bearing , water-deposited layers . This uplift of the new continental land-masses from under the Flood waters would have meant that , as the mountains rose and the valleys sank ( as Psalm 104 suggests ) , the waters would have rapidly drained off the newly emerging land surfaces . The collapse of natural dams holding back the floodwaters on the land would also have caused catastrophic flooding . Such rapid movement of large volumes of water would have caused extensive erosion and shaped the basic features of today 's Earth surface . As a result of this extensive erosion ( caused by the retreating Flood waters ) it is not hard to envisage the rapid carving of the landscape features that we see on the Earth today , including places such as the Grand Canyon of the U.S.A . The present shape of Uluru , a sandstone monolith in central Australia , is the result of erosion , following the tilting and uplife , of previously horizontal beds of water-laid sand . The feldspar-rich sand that makes up Uluru must have been deposited very quickly and recently . Long-distance transport of the sand would have caused the grains to be rounded and sorted , but we do n't see this at Uluru , i.e . they are jagged and unsorted . Which indicates rapid transportation ( like through a cataclystic Flood ) . If they had sat accumulating slowly in a lake bed drying in the sun over eons of years , which is the story told in the geological display at the park centre , the feldspar would have weathered into clay . Likewise , if Uluru had sat in hte once-humid area of central Australia for millions of years , it would have weathered to clay . But besides the `` fact `` that it has reportedly been exposed to weathering for hundreds of millions of years , the feldspars are still very fresh , as though they were exposed only yesterday . Similarly , the nearby Kata Tjuta are composed of an unsorted mixture of large boulders , sand and mud , indicating that the material must have been transported and deposited very rapidly . Receding floodwaters eroded the land , creating river valleys . This explains why rivers are often so much smaller than the valleys they flow in today - they did not carve the valleys . The water flow that carved out the river valleys must have been far greater than the volume of water we see flowing in the rivers today . This is consistent with voluminous Flood waters draining off the emerging land surfaces at the cose of Noah 's Flood , and flowing into the rapidly sinking , newly prepared , deep ocean basins .
