10 Facts about Chemical Weathering

Friday, November 27th 2015. | Science


The process of breaking down materials due to the contact with water, biota and atmosphere is explained on Facts about Chemical Weathering. The materials broken down include minerals, soils and rocks. Weathering is very is different with erosion since it occurs in situ. It means with no movement. There are two processes of weathering. It can be chemical or physical. Get other facts about chemical weathering below:

Facts about Chemical Weathering 1: physical weathering

Physical weathering is also called mechanical weathering. When the materials have contact with here, water, pressure, and ice, it is included in the physical weathering due to the presence of atmospheric condition.

Facts about Chemical Weathering 2: chemical weathering

Chemical weathering occurs when the rocks, minerals and soils have contact with the biology called produced chemicals or atmospheric chemicals. Find facts about chemical bonding here.

Facts about Chemical Weathering 3: the climate

The climate affects the presence of physical and chemical weathering. The chemical weathering occurs when the climate is hot and wet.

Facts about Chemical Weathering 4: the changes in chemical weathering

The composition of rock is changed when it faces the chemical weathering process. It happens when mineral and water interact each other. Both can form chemical reactions.

Facts about Chemical Weathering 5: a gradual process

Chemical weathering is not an instant process. But this process is ongoing and gradual. The oxygen and water are considered as the geological agents who increase the chemical weathering process.

Facts about Chemical Weathering 6: the biological agents

The biological agents such as the presence of acids generated by the plant root metabolism or microbial metabolism can increase the chemical weathering too.

Facts about Chemical Weathering 7: the important processes during chemical weathering

During the chemical weathering, some important processes which take place include hydrolysis and oxidation.

Facts about Chemical Weathering 8: Rainfall

The acid is an important agent in chemical weathering. It is can be gained from rainfall. The pH of rainfall in unpolluted areas is 5.6. Get facts about chemical reactions here.

Facts about Chemical Weathering 9: the presence of acid rainfalls

When the nitrogen oxides and sulfur dioxide are presented in the atmosphere, the acid rainfall occurs. The pH can reach 4.5 or even 3.0 since both can produce the stronger acid.

Facts about Chemical Weathering 10: the negative effect of acid rain

Due to the acidic feature of the acid rain, the buildings made of concrete, brick and stone are prone to chemical weathering. It is easier for them to get damaged. The surface should be protected with the right sealant.
