What Is The Difference Between Physical And Chemical Weathering

Chemical weathering entails transformation and modification of mineral components and thus it the entire process is slower when compared to physical weathering.

Physical and chemical weathering degrade rocks in different ways. Rocks may decompose or dissolve and at the same time changes in composition through a certain chemical process to form residual materials. Whereas chemical weathering mainly takes place due to rain. Physical weathering works with mechanical forces such as friction and impact while chemical weathering takes place at the molecular level with the exchange of ions and cations.

Physical weathering is a gradual process though faster than chemical weathering. Physical weathering may result due to temperature pressure snow etc. This is called chemical weathering. While physical weathering breaks down a rock s physical structure chemical weathering alters a rock s chemical composition.

It doesn t impact the composition of minerals or metals compounds or any such formation property of the object. Chemical weathering causes a change in the composition texture form and properties of an object. Explain the differences between physical and chemical weathering. Minerals inside the rock do not dissolve completely.

Mechanical weathering simply affects the structure or the physical form size weight and the texture in rare cases. Weathering happens when there is a breakdown physical or chemical to the surface mineral of rocks. Erosion or weathering takes place when a rock or other substance is broken down and swept away by various forces. Physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions such as heat water ice and pressure.

See more previous article difference between physical and chemical properties. Physical weathering breakdown rock into smaller pieces with no changes while chemical weathering breakdown rocks into new material with the use of weak acid and reaction to air. Physical weathering vs chemical weathering physical weathering does not change the chemical composition of the rock whereas chemical weathering changes the composition. Whereas chemical weathering involves the direct effect of atmospheric chemicals or biologically produced chemicals in the breakdown of rocks soils and minerals.

The primary difference between physical weathering and chemical weathering is that physical weathering occurs landforms like rocks minerals and likewise substances are broken down by physical factors in the environment while chemical weathering occurs as a result of changes in the chemical composition of the minerals or rocks from exposure to the environment.
