Not as a storm, flood or earthquake might. But even there, a landscape has always been previously modified by earlier periods of erosion. It’s an ongoing, continuous process.

Indeed. The YEC theory seems to posit that you can remove nearly all of the cyclic thermal stresses and periods of slow erosion that would be present under Old Earth theory, and still have the same end result from just a relatively few major events.

Many if not most forms of erosion leave tell-tale signs behind indicating what process it was. The products of the really slow ones would look differently in some respects than those of the rapid or catastrophic forms, such as floods and storms.
