==================================
WEATHERING IS THE PROCESS OF DISINTEGRATION OR DECOMPOSITION OF A ROCK DUE TO VARIOUS KINDS OF PHYSICAL, CHEMICAL OR BIOLOGICAL AGENTS.
==================================
⚡ EFFECTS OF WEATHERING ⚡
➡ SOIL FORMATION : The soil formed by the weathering process is very fertile. In limestone areas, the chernozem soil is formed due to weathering by the process of Carbonation.
➡ REGOLITH FORMATION : Disintegrated fragmentary cover of loose rock materials accumulated altogether is called regolith. It is formed due to weathering process. The upper part of REGOLITH under suitable conditions is transformed to soil.
➡ FORMATION OF MINERALS OR ORES : Weathering helps in the formation of various kinds of minerals and ores such as aluminium, silica, bauxite, manganese, iron, etc.
➡ PRODUCTION OF LANDFORMS : Different kinds of landforms formed due to the rapid action of weathering. Specially the Plateaus are most popular examples of landform formation by weathering process.
➡ INCREASED SOIL FERTILITY : Weathering process makes the soil more porous as well as fertile making it suitable for growing crops.
⚡⚡ REGOLITH ⚡⚡
➡ The disintegrated fragmentary cover of loose rock materials which gets accumulated altogether by the process of weathering is called as regolith. The upper part of regolith under suitable condition is transformed into soil.
⚡ FORMATION OF SOIL BY WEATHERING ⚡
➡ The term "weathering" means disintegration or decomposition of rocks by various types of physical, chemical or biological agents. Mass wasting, erosion, denudation, etc., all leads to weathering. Weathering causes the formation of REGOLITH which is the disintegrated loose fragmentary cover of rock. The upper portion of this regolith under suitable conditions gets transformed to soil. Thus, weathering helps in the formation of soil. It (Weathering) also makes the soil fertile amd porous so that the soil becomes airy.
