In time, however, the stream cutsso low that further deepening is eithergreatly checked or wholly stopped. Weath-ering, however, continues to broaden thevalley which is no longer being deepened,and this carving of the plain in time pro-duces broadly sloping valleys and gentlyrounded hills. This stage is reached muchmore quickly in a moist than in a dry cli-mate, because the agents of weathering aremore active in the former than in the is one of the reasons why the plateausof the arid West are crossed by ruggedand narrow canyons, while that near the baseof the Appal
