If it is on rivers that are in highlands (up in the mountains and are usually narrow) it is gravity, so it erodes downwards. However, if it is in lowlands (in a valley or a flood plain, for example) it is usually the sheer force of water - in other words, the hydraulic action of water + sediments carried by water. Wind can also contribute to water erosion, as it causes waves and it accelerates the water speed.
it doesn't happen on the moon ... there no wind , water or any thing else that causes erosion on the moon :)
The faster the speed of water in a river the more erosion is causes. The slower the water the less amount of erosion it causes.
The type of erosion that causes sand is water erosion.

water erosion
Main causes are water and the wind.
An increase in volume or velocity of the water will increase erosion
Rain

Gully erosion, a type of water erosion.
Wind, ice, and water are the causes of erosion
wind and water are the 2 causes of weathering and erosion
