Answer 1

Wind can use sand as an abrasive to wear away rock.

Option (d);

EXPLANATION:

• 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.
