Parent Material

It can be comecck (igneous, sedimentary, or metamorphic) or unconsolidated deposits such as glacial till, loes (windblow silt), alluvim, or coasusal sediments.

Types of Soils and Their Relationship to Landforms

Te soil classification system most widely used internationally is Soil Taxonomy (USDA) or thee Worlds Reference Base (WRB). At te highest level (orders), soils are grouped by key diagnostic condibures that often correlate with landform andd climate. Understanding these accordisations aids in land- use planning and environmental management.
