a) down cutting
b) headward erosion
c) lateral erosion
d) vertical erosion​

Answer 1

● Sometimes, the river starts erosion upstream. This happens when the head streams gets lots of water in the early stages of river flow. Such type of erosion is called headward erosion.

● The headward erosion is typically characterized as an erosional procedure where the fundamental specialist is water, that outcomes in the protracting of a stream or waterway channel at its head.

● It slowly prompts the extension of the waste bowl.

● The stream climates and dissolves the dirt particles and rock pieces at its headwaters that are inverse to the stream bearing.

● The pace of disintegration step by step increments once the headward downcutting begins and in the end shapes more extreme slants and the flimsier rocks are cleaned out more quickly.

● It likewise augments the stream channel.
