The Processes of Rocks
There are three types of weathering:
Physical weathering is the temperature change in rocks causing them to break down. A sedimentary rock goes through the freeze-thaw process and during the day breaks straight down the middle.
Chemical weathering is the breaking down of rocks by a chemical reaction. An igneous rock goes through the carbonation process.
Biological weathering is the breaking down of rocks by plants, animals, and other organisms. A tree grows through a metamorphic rock over time.
Two landforms that have been formed through erosion are the waterfall carrying sediments in Admiralty Inlet in Canada and the Grand Canyon.
Two landforms that were formed by or form deposition are the Newton Clark moraine, a moraine in the western greenland, and a glacial moraine.
How is Soil Used?
Soil is important in North Carolina because it is used for many of the things listed above, and especially farming!
What type of Soil is Found in North Carolina?
organic soil-typical in wetland areas such as marshes, swamps and bogs. Organic soils form in areas where high rainfall and poor drainage allow organic matter to collect over time.
sandhill soil- loose, gray sandy soil, commonly found in the Coastal Plain region of North Carolina.
