exfoliation
To determine the correct answer to the question, "Abrasion occurs due to _____," we can analyze each response option one by one.
1. Friction: This is a plausible answer since abrasion is the process of wearing or scraping away a material's surface due to frictional forces.
2. Plants and animals: This answer seems unrelated to abrasion. While plants and animals may cause erosion or damage to surfaces, they do not directly cause abrasion.
3. Daily temperature changes: Temperature changes alone do not lead to abrasion. While frequent temperature fluctuations may cause physical changes in some materials, they do not necessarily result in abrasion.
4. Seasonal temperature changes: Similar to daily temperature changes, seasonal temperature changes on their own do not cause abrasion.
Based on this analysis, the most appropriate answer to the question is "friction," as abrasion primarily occurs due to frictional forces.
Abrasion occurs due to friction.
