14.
Explain the differences in the size and shape of the material on the river bed in the upper and lower courses of a river
a)
A. In the upper course load is smaller and more rounded than in the lower course because of erosional processes such as attrition and corrasion.
b)
B. As a river moves through its course, because of the greater incidence of larger settlements, more supermarket shopping trolleys are likely to be found in rivers, adding to the load that has already been deposited.
c)
C. In the lower course load is smaller and more rounded than in the upper course because of erosional processes such as attrition and corrasion.
15.
Give reasons for the differences in cross sections of rivers in the upper and lower courses
a)
A. In the upper course rivers are narrow and swallow because the river is less powerful and discharge relatively low. In the lower course the river is wider and deeper as the river carries more load, discharges more and has more power to erode.
b)
B. In the upper course rivers are wide and deep because the river is less powerful and discharge relatively low. In the lower course the river is narrow and shallow as the river carries more load, discharges more and has less power to erode.
c)
C. As a river moves from its upper to its lower course, it tends to carry more load, is wider, deeper, faster flowing and discharge increases
