Stream will eventually erode wall away until local base level and ultimate base level differentiation disappears *** erodes until local base is at sea level**V. Changes in levelsa. Base levelsi. Raising causes erosionThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.ii.
