Soil of northern Guam
Soil is unconsolidated natural matter on the immediate surface of the earth. It is a mixture of rock fragments, minerals, organic matter, water, and other materials and serves as a natural medium for the growth of plants. It forms through disintegration of rocks by physical, chemical and biological processes. Soil conditions, such as type, permeability, and moisture, greatly affect how land may be used, determine the potential for vegetation and habitat, and influence overland runoff that causes erosion and land slides.
