Rarity color In environments characterized by humid conditions that extend for many thousands to millions of years, water may penetrate deep into bedrock to form saprolite, a rock made from the consolidation of clay minerals that remain from the chemical weathering process. Soil is a complex mixture of minerals (approximately 45%), organic matter (approximately 5%), and empty space (approximately 50%, filled to varying degrees with air and water). However, the date of retrieval is often important. This layer usually contain concentrations of clay minerals or of iron or aluminium oxides. Soil forms most readily under temperate to tropical conditions (not cold) and where precipitation amounts are moderate (not dry, but not too wet). Soil forms through accumulation and decay of organic matter and through the mechanical and chemical weathering processes described above. Variations in these two types give rise to a wide area of soil types. To unlock this lesson you must be a Study.com Member. Tillage is also a factor in soil erosion, especially on slopes, because each time the soil is lifted by a cultivator, it is moved a few centimetres down the slope.
