<u>EXPLANATION: </u>
- Rocks are broken down into smaller pieces with sand or water flowing over the rocks at a great speed.
- Many solid particles like soil, sand, mud, etc. move down the rocks by downhill or wind blowing in the downward direction and called wind abrasion.
- Sand blown with the help of high speed, sandblast away the rocks.
- Abrasion is a process in which sand is blown in downwards direction with the help of wind and that wears away the rock's surface over time.
- Thus, wind uses sand as an abrasive to wear away a rock.
