Weathering, Erosion and Soils

The pedosphere is like the “skin of Earth”. Just like your skin, it has a thin outer surface. It also has pore spaces and dries out without enough moisture. […]

Plants mostly use water and carbon dioxide from the air to grow. But nutrients like nitrogen (N), phosphorus (P) & potassium (K) are also key ingredients. […]

Soil formation is vital for food production and plant growth. Weathering is the process that breaks rock down into soils. Without it, soil wouldn’t exist. […]

Biological weathering can occur from mechanical force and chemical reactions such as through plants, bacteria, fungi, burrowing animals and living organisms […]

From the remarkable process of plates colliding and building mountains. They are only to be dismantled by mass wasting (weathering, erosion and transport). […]

Mechanical weathering is the breakdown of rocks into sediments by physical means.This type of weathering does not alter the chemical composition of rocks. […]

Chemical weathering is the process of transforming a rock’s composition through chemical reactions (by dissolving or converting them into other minerals) […]
