1. describe how does weathering break down or change rock?
Answer
Brief Explanations:
Weathering is a natural process. Physical weathering breaks rocks through temperature changes, frost - wedging etc. Chemical weathering changes rock composition through reactions like oxidation and dissolution. Biological weathering involves living organisms like plants and animals breaking down rocks.
Answer:
Weathering breaks down or changes rock through physical, chemical, and biological processes. Physical weathering can be due to temperature changes causing expansion and contraction, or frost - wedging where water freezes and expands in rock cracks. Chemical weathering occurs when substances in the environment react with the rock's minerals, for example, oxygen can cause oxidation of iron - containing minerals in rocks. Biological weathering is when plants grow into rock crevices and widen them, or animals burrow through rocks.
