Soil Study Guide Clay Moist slippery earth usually red in color. Clay is often found in Georgia. Plants do not generally grow well in clay. Erosion The carrying away of soil and weathered materials through wind, water, or other causes. Humus A material that was once living or was formed by living things. Loam A kind of soil that contains clay, sand, silt, and humus. Plants grow well in loam. Minerals A naturally occurring substance, neither plant nor animal. Silt Dry, dusty soil. Soil A mixture of tiny rock particles, minerals, and decayed plant and animal materials Subsoil The layer of soil located below the topsoil. It has bigger, lighter colored soil and lacks humus. Subsoil does hold water and some minerals. Topsoil The top layer of soil. It is made of very small, dark particles and has a lot of humus and minerals. Topsoil holds a lot of water. Weathering The process that causes rocks to crumble, crack, and break. Students should be able to identify the 3 different layers of soil. Students should be able to identify regions of Georgia that contain the various types of soil. Students should be able to identify the characteristics of clay, loam, and soil. (See below) Clay Soil type Texture Smooth and powdery Red Color Grain size Smallest particle size Loam/potting soil Soft and clumpy Dark brown or black Medium size particles Sand Rough and gritty Varies in color across the world Largest particle size Holding water Does not let water pass through easily Holds water well. Best for growing plants Lets water pass through easily
