abrasion or the wearing away of rock by a grinding action.
rate of stream discharge is directly proportional to the erosion i.e the higher the velocity of the stream then it will erode the rock rapidly while the deposition process will be slow when the velocity will be high.
The base level
The major factor should be its speed. The higher its speed, the more force the stream will hit the bank and bed, making the land erode more easily.
Wind erosion is an ongoing process.
Wind causes erosion by deflation and abrasion. Deflation is the process by which wind removes surface materials.
Streams can't erode their channels endlessly. there is a lower limit to how deep can a stream erode. Base level is the lowest point to which a stream can erode its channels.

Stream erode their channels by abrasion, grinding, and by dissolving soluble material.

The gradient of a stream effects the energy as it has eroding soil and rock. This happens because depending on the pressure of the water flow, it can erode soil and rock.
