What is the main difference between abrasion and attrition?
Answer and explanation
Correct answer: In abrasion tools cut rock and in attrition particles collide and become smaller
Abrasion and attrition are different erosion mechanisms. In abrasion, transported particles such as sand, pebbles, or ice-embedded debris act as tools and scrape or grind a rock surface. In attrition, the transported particles collide with one another during movement, causing them to fracture, become smaller, and often more rounded. Therefore option C correctly distinguishes the processes; the other statements are scientifically incorrect.
