select the correct answer. which of these processes was able to occur in earths early atmosphere before living organisms existed? a. corrosion of metals b. oxidation of minerals c. erosion of soil d. combustion of fuels
Answer
# Brief Explanations:
1. Corrosion of metals usually requires oxygen and often involves biological - influenced processes in the long - term.
2. Oxidation of minerals can occur without living organisms. In Earth's early atmosphere, there were reactive chemicals like oxygen (even if in different forms or concentrations than now) that could cause mineral oxidation.
3. Erosion of soil requires the presence of soil, which is formed over time with the help of living organisms and weathering processes that are often related to biological activity.
4. Combustion of fuels requires the presence of combustible materials and usually oxygen in a suitable form, and often involves biological or organic - derived fuels.
# Answer:
B. oxidation of minerals
