• BasicsDepositional Environments

    The layers of sediment that accumulate in each type of depositional environment have distinctive characteristics that provide important information regarding the geologic history of an area. The characteristics that can be observed and measured in a sedimentary rock to deduce its depositional environment include its lithology (which is essentially its rock type), its sedimentary structures ...

  • FOUR LAYERS OF SOIL

    FOUR LAYERS OF SOIL. Soil is made up of distinct layers, called horizons. Each layer has its own characteristics that make it different from all of the other layers. These characteristics play a very important role in what the soil is used for and why it is important. O HORIZON This is the top layer of soil that is made up of living and decomposed materials like leaves, plants, and bugs. This ...
