Document Summary
Fast moving water can pick up heavier objects, as the water slows the heavier objects are deposited. These materials accumulate and create floodplains along the water table level. Glacial deposits create different soil formations and landscapes. This can be seen through the different types of vegetation or elevations. Also by taking a look at the soil profiles. On the top of a hill, there is a very simple soil profile. The soil is dryer up on top of elevations. At the bottom of the hill, the water that has travelled down and creates a much wetter soil, and also creates a more complex soil profile because of all the nutrients the water brings with it. Also on the hill, there is a lot of erosion from water, so the soil is very thin. Soil formation is a complex process that takes place over decades or centuries.
