Abrasion occurs due to _____.
A Plants and animals
B Daily temperature changes
C Seasonal temperature changes
D Friction
D Friction
D Friction
The answer is D. Friction.
To arrive at this answer, let's break down the options and analyze them one by one:
A. "Plants and animals": This option is incorrect because abrasion refers to the process of wearing down or scraping the surface of a material through friction, not due to the presence of plants and animals.
B. "Daily temperature changes": While temperature changes can cause expansion and contraction of materials, which might lead to wear and tear over time, it is not the primary cause of abrasion.
C. "Seasonal temperature changes": Similar to the previous option, while seasonal temperature changes might affect the expansion and contraction of materials, they are not the main cause of abrasion.
D. "Friction": Friction is the correct answer. Abrasion occurs when two materials or surfaces rub against each other, causing particles or layers to be worn away. This can happen due to direct contact or through the use of abrasive substances or tools.
In conclusion, abrasion occurs due to friction, making option D the correct answer.
