Question 5 – Water on the land5 (a) Near the source, the cross profile is narrow, steep sided and relativelydeep valley (1). As movement occurs downstream, the cross profilebecomes wider, less deep and the valley sides are less steep (1).Nearest the mouth, the valley is especially broad, the sides are a longway from the river and these are gentle and very low lying. (1)There should be 3 statements that convey change downstream. Theabove is one strategy – going site by site, other approaches may referto stages or the characteristic of an individual change that takes placedownstream. Accept river channel changes as well as valley.3 x 1 per stage or overall change from source to mouth.
