In chemical weathering mosses and linches have been found to grow on rocks and release chemicals that dissolve minerals from rocks. roots from plants are able to invade cracks with in rocks and increase the size of the cracks. There are a number of trees and other plants that release acidic chemicals which can cause weathering of the rocks, minerals, and soil around them. Plants also can have an affect on the way water weathers rocks and soils, they can channel water in specific directions that cause greater weathering or they can lessen the impact of rain falling on the ground. They also affect wind speed and direction near the surface of the ground having an effect on weathering in arid regions of the world.

∙ 13y agoPlants can cause chemical weathering and mechanical weathering because in mechanical weathering plants grow their roots in the cracks of rocks. In chemical weathering plants grow their roots in the cracks of rocks, and the roots release acid that weathers away the rock.

∙ 10y agoPlants can cause physical weathering by their downward root growth into the soil and rock surface, thereby resulting to creation of cracks and expansion of crevices and breaking down of the soil or rock material into smaller fragments.

∙ 12y agoThe roots of a plant can commonly grow into existing cracks in rocks.As the plant grows, the force of its expanding roots becomes so strong that the cracks widen.In time, the whole rock can split apart .

What are some differences of physical weathering and chemical weathering?
Physical weathering is due to: rocks hitting other rocks causing them to break up from the action of frost and ice the action of wind or waves or running water the action of plants. Chemical weathering changes the composition of the rock and is due to: water dissolving minerals in the rock oxidation of metals in the rock
Real life example of chemical weathering?
The main agents of chemical weathering are acid precipatation, lichens, and other plants like mold decaying the rock. :)
What are the most important factors in chemical weathering?
Erosion..... As wind, water, and glaciers move rock debris, they relentlessly disintegrate the rock further.
What are three causes of chemical weathering?
Chemical weathering is the dissolution, carbonation, oxidation, or hydrolysis of rock and mineral by chemical means only, mostly from reactions with water or the acids contained in rainwater.Other materials are formed in the process. Warm, tropical climates are ideal environments for chemical weathering to take place as the chemical reactions are quickened by the bountiful rain and warm temperatures. Water, oxygen, carbon dioxide, living organisms, and acid precipitation.
How can a river both cause a chemical and physical weathering?
Water is a major component in weathering process. Its essential for all forms of disintegration either Mechanical/Physical, Biological or Chemical. Water aids in physical weathering through alternating wetting and drying of rocks thereby leading to breaking down of the rock. It helps in chemical weathering through dissolution of chemicals in rocks such as limestone. Water is a cause of both chemical and physical weathering.
What is three ways in which weak acids can cause chemical weathering of rock?
well the acid rain will make the plants die but chemical weathering can help pastad is a yellow grainy shadow to help the sentaped weathering breaks into the soil
How does air cause chemical weathering?
It breaks rock apart.
How are mechanical and chemical weathering affected by plants?
to be honest in mechanical weathering plants grow their roots in the cracks of rocks. In chemical weathering plants grow their roots in the cracks of rocks, and the roots release acid that weathers away the rock.
What living things attaches to rock and cause chemical weathering?
Lichen.
What do plants do to cause weathering?
As plants grow out from cracks in rock, they push the rock further apart, and eventually it breaks apart.
What is weathering that does not alter the chemical composition of the rock called?
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
How does Biology cause weathering?
•Organisms (especially plants) excrete acids both to extract nutrients and to build roots •Cause rock weathering
What does mechanical weathering of rock mean?
any of the various weathering processes that cause physical disintegration of exposed rock without any change in the chemical composition of the rock
While physical weathering will break a rock into chunks what turns the rock into soil?
chemical weathering
How do mosses and lichen cause chemical weathering?
By they acid in the substances it weathers the rock away.
What are physical and chemical weathering?
Physical Weathering: is when a rock is broken into smaller and smaller pieces. Chemical Weathering: is when the rock change due to different chemical reactions.
Explanations of the three types of weathering?
chemical weathering is when a chemical reacts with a rock to brake down a rock.
