To find the answer to this question, let's analyze each option:
1. Plants and animals: This option is incorrect as abrasion refers to the process of wearing, grinding, or scraping of materials typically caused by friction, not by plants or animals.
2. Seasonal temperature changes: This option is also incorrect as abrasion is not caused by changes in temperature throughout the year. While temperature variations may affect the behavior of materials, they do not directly cause abrasion.
3. Daily temperature changes: Similar to the previous option, abrasion is not caused by daily temperature changes. While temperature fluctuations may impact the expansion and contraction of materials, they do not directly cause abrasion.
4. Friction: This option is correct. Abrasion occurs due to friction, which is the resistance encountered when two objects move against each other. The rubbing or scraping of one object against another can lead to the wearing away of material, resulting in abrasion.
Therefore, the correct answer is "friction."
