In case you come back nutrider:
Deserts erode, their sand is lifted and moved to other locations, making it to rivers and oceans and piling against mountains. Limestone, chalk, salt and sandstone exposed to the sun and wind becomes airborn, fine material is continually moved around until it encounters water.
"erosion
noun
1. the act or state of eroding; state of being eroded.
2. the process by which the surface of the earth is worn away by the action of water, glaciers, winds, waves, etc."
Remember this? You posted it, must be Websters with that "etc' in there, not a good defining word. Apparently you think eroded material disappears,stays suspended in water or faces a stronger gravity at some point.
Also, unless under continual rapid flow (most rapid flows are seasonal) much sediment is locked into river and lake beds from being mixed together and packed.
Where the hell do you think fine materials the water can carry come from?
The Grand Canyon floods and heavy currents not only wore away at the softer material they left the harder or carved out paths that carried and the later lighter flows.
If your arguement is that the Grand Canyon was full of sediment that filled it in until your stupid flood story, explain how that sediment got there. Where'd a mile deep of sediment come from before your retarded flood story?
Honestly, stick with your Childrens Illustrated Bible and stay away from trying to explain erosion or hydrolic forces, you haven't a clue.
Sediment is eroded material piled up due to natural causes (Period)
