Explore: Soil Weathering

chemical weathering is also called biological weathering. The materials left after the rock breaks down combine with organic material to create soil. Many

(nutrients) released by weathering and produce organic acids and specialized proteins which contribute in turn to mineral weathering. They also leave behind

physical weathering or disaggregation) and chemical (changing the chemical compounds in the rocks). Biological weathering is a form of weathering (mechanical

where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as physical

small particles to create soil. Weathering mechanisms are physical weathering, chemical weathering, and biological weathering Human activities such as excavation

weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most soils have

method for soil pH determination The pH of a natural soil depends on the mineral composition of the parent material of the soil, and the weathering reactions

Salts occur naturally within soils and water. Salinization can be caused by natural processes such as mineral weathering or by the gradual withdrawal

A soil horizon is a layer parallel to the soil surface whose physical, chemical and biological characteristics differ from the layers above and beneath

Space weathering is the type of weathering that occurs to any object exposed to the harsh environment of outer space. Bodies without atmospheres (including
