Answer 2

Interlocking Spurs - As the river cuts its deep V-shaped valley in its upper course, it follows the path of the easiest track to erode. Thus it tends to wind its way along, leaving the more resistant areas of rock as interlocking spurs.
Meanders - Meanders occur in the mid course and lower course of the river, where it is beginning to cut laterally as it gets closer to base level. Meanders are basically bends in the river, where the faster water on the outside of the bend has cut into the bank, eroding it and creating a river cliff. At the same time the slow moving water on the inside of the bend deposits its load, building up a shallow slip-off slope. Meanders migrate downstream as they cut through the valley sides.This creates a line of parallel cliffs along the sides of the valley.
Ox-Bow Lakes - In the lower course of theriver meanders can become so pronounced that they can form ox-bow lakes. Inthe lower course the rapid lateral erosion cuts into the neck of the meander, narrowing it considerably. Eventually the force of the river breaks through the neck, and as this is the easiest way for the water to go, the old meanderis left without any significant amount of water flowing through it. Quickly the river deposits material along the side of its new course, which completely block off the old meander, creating an ox-bow lake.
V-shaped valleys - In the upper course ofthe river, it cuts rapidly downwards, as the river puts almost all of its energy towards cutting down to base level. This causes the most distinctive river feature, the V-shaped valley. Rocks and other material are washed into the river from the steep valley sides during times of heavy rainfall, adding to the material being carried by the river.

Waterfalls - Waterfalls are perhaps the most spectacular erosional feature of a river. They primarily occur in the upper course of the river. Often a waterfall will form where a band of harder rock lies over a softer one. As the river flows over the edge of the harder, more resistant rock, into its plunge pool, it erodes away the softer rock below, creating an overhang. Once the overhang is big enough the whole thing collapses due to gravity and its own weight. The whole process then occurs again. This means that over time waterfalls will move backward up the valley, leaving a steep-sided gorge in front of them.
