What process takes place during the youthful stage of a river? (1) Valley widening (2) River rejuvenating (3) Valley deepening (4) Meandering
by

1 Answer

Answer :

(3) Valley deepening Explanation: The youthful stage of the river is when water flow is the quickest. Because of steep slope and steep channel gradient in this stage, rivers actively deepen their valleys through vertical erosion. The valley becomes deep and narrow characterized by steep valley side slopes of convex plan. Waterfalls, Vshaped valleys and interlocking spurs are features of this stage.
