Which describes the Grand canyon as it will be one million years from today?

I think it will become shallower and narrower.  

Explanation:

This is because today, the Grand Canyon is deep and wide, we are talking about how it was one million years ago, which would look noting like this today. Little piece of rock has started to fall off of the sides of the Grand Canyon so it looks how it looks today.
