Water collecting on the surface of the soil collects as it moves towards tiny rivulets . Larger particles will sink to the bottom early on in their journey because they are denser than the small particles that make their way to the end where the stream or river empties into a bigger body of water. When the two layers stop mixing, the upper layer becomes more stable (no wind-induced mixing, convection cells)and summer blooms of buoyant blue-green algae are supported. 2 What are the possible materials or compositions of rock strata?
