Respond to the following question or statement in the space provided below, in complete sentences . Compare how clay and sand behave differently during erosion by water using the concepts of transportability and detachability of particles. Clay has low detachability and high transport while sand has high detachability and low transport. Particle density will vary greatly but it is valid to use a constant value for bulk density in most soils. An increase in bulk density will result in a decrease in soil porosity.
Sandy soils have more micropores than clayey soils.
Organic matter affects porosity through its enhancement of soil aggregation. T B. Decide which response most correctly matches each of the following and circle your choice. Archimedes Principle states that an object placed in a liquid is buoyed up by a force equal to the weight of the displaced liquid. A 250 cm 3 cylindrical container was used to collect an undisturbed soil sample. The container and soil weighed 500g when oven-dry.
