How would you explain how there is little erosion in the layers of the Grand Canyon?

   The parts that have been eroded can no longer be seen, seeing as they aren’t there.

   <<I honestly have no idea how to explain this to him; never really studied it.>>

   You don’t have to explain it. Let them believe whatever they like. Even if you could explain most wonderfully and logically, they probably won’t believe you anyway.

   the grand canyon is eroding. look at pictures. you can see layers of rock,soil.

   but! the grand canyon is sort of a desert(with a river going threw it) so theres not much rain,wind,weather for erosion to happen.

   The fact that the Colorado River is so muddy reveals the huge sediment load that the river is carrying. Where do you think all that sediment comes from?

   Actually a lot of Creationists believe that the world is really old anyway – just all designed of God – in the beginning. How do people who dont believe in God explain how the matter for the Big Bang got there?

   Your friend like all the Young earth Creationists is so far offbeat he is not even wrong.

   The entire cutting of the canyon is an example of erosion!

   Ask him where all the sediment entering Lake Mead comes from?

   (it comes from the erosion of the Grand Canyon).

   Er… isn’t the whole thing a ruddy great eroded hole?!

   This should shut him up. Tell him that the Redwall limestone layer, which is about half way up the canyon wall, contains the remains of an ancient karst system. Karst systems form when limestone is eroded by rainwater over thousands of years, forming very distinctive caves and sink holes.
   This means the Redwall was formed on the bottom of the sea, was compressed into limestone, then it was lifted out of the sea, it was eroded to form the karst system, then it subsided again, was covered with other sediments, then the whole lot was lifted by geological activity to create the Colorado plateau, but slowly enough to allow the river to cut a huge canyon through it. Ask him how long he think that took.

   There is one huge piece of evidence demonstrating erosion in the Grand Canyon: the canyon itself.

   How did the canyon get there if it wasn’t by erosion form the Colorado river?
