The valley gets narrower
The gradient gets steeper
You find interlocking spurs in the upper course
The watershed is the highland that surrounds the watershed
Deltas are found at the river’s mouth
Wide flood plains are found in the upper course
A confluence is when 2 rivers meet
Tributaries are bends in rivers
