Studying Soil

As you dig down into the ground the soil composition (the way the soil is made up) changes. There are four distinct layers of soil under the leaf litter.

Your teacher will use a soil auger to take a sample of soil from the ground which includes the four layers shown under the leaf litter in the illustration above. While you are in the forest you will be asked to observe these layers and write a few words about the appearance of each of them.
