उत्तर
polythene bags
Explanation:
Temperature variations due to radiations from the sun, rainwater and wind are major biotic factors that influence the formation of soil from rocks. Polythene bags do not participate in the formation of soil. They are non-biodegradable substances that do not undergo decomposition or weathering. These are considered pollutants that deteriorate the quality of the soil.
