1. INTRODUCTION TO SOIL MATERIALS
WebThe organic and inorganic material in which soils form is the parent material. Mineral soils form directly from the weathering of bedrock, the solid rock that lies beneath the soil, and therefore, they have a similar composition to the original rock. Other soils form in materials that came from elsewhere, such as sand and glacial drift. WebThe cross section below shows a soil profile. This soil was formed primarily by (1) erosion by glaciers (2) erosion by running water (3) capillarity and human activity (4) weathering and biological activity 50.
