Here's an experiment: Take home a chunk of rock from the area around the grand canyon. Pour running water over the rock for the next 1 year. See how fast the rock washes away.
Has anyone actually conducted this experiment? How much of the water was eroded in one year?
Can someone provide the specifics of how this experiment was conducted and the factual rock erosion measurements?
1) 1 mm per day?
2) 1 mm per year?
3) 1 mm per century?
4) 1 mm per millennium?
5) 1 mm per million years?
Anyone?
Dangus, you have implied that a rock obtained from the Grand Canyon, with water pouring upon it for one year, will have a measurable errosion.
What was the actual errosion amount?
"Has anyone actually conducted this experiment? How much of the water was eroded in one year? "

What? Water get's polluted...And I know it freezes and evaporates...but how does water itself "erode".
BTW....if I'm not mistaken...scientists from all over the world were amazed at how fast the landscape changed dramatically in the days, weeks, months, years after Mt. St. Helens exploded.
Seems...if I remember correctly that many were forced to re-examine their theories and timelines on erosion, canyon formation/creation..etc..etc....
FWIW--
