Question

describe an activity to show that a soil can diffuse slowly into a liquid

Answer 1

the soil varies depending on the person considering it. To a civil engineer planning a construction site, soil is whatever unconsolidated material happens to be found at the surface. To a miner, it is just some worthless material that is in the way and must be removed. To a farmer, it is the medium that will nourish and supply water to the crops. Even soil scientists may hold differing definitions, depending on their area of study.
