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.

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.
Is plants in the crack of rocks a cause of weathering?
Yes, plants growing in cracks of rocks can contribute to weathering. As the roots of the plants grow, they can exert pressure on the surrounding rock, causing it to crack and break apart. Additionally, the growth of plants can lead to the accumulation of organic material that can accelerate chemical weathering processes on the rock surface.
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 happens when a rock Is chemical weathering?
Chemical weathering of rock occurs when minerals within the rock are broken down or altered through chemical reactions. This can lead to the formation of new minerals, decomposition of the rock's structure, or dissolution of the rock into smaller particles. Over time, chemical weathering can weaken the rock and cause it to disintegrate.
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.
How does Biology cause weathering?
•Organisms (especially plants) excrete acids both to extract nutrients and to build roots •Cause rock weathering
What processes can cause rock to breakapart into sediment?
Weathering processes such as mechanical (physical) weathering, chemical weathering, and biological weathering can cause rocks to break apart into smaller pieces or sediment. Mechanical weathering includes processes like freeze-thaw cycles, abrasion, and root wedging. Chemical weathering involves reactions with water, oxygen, and acids that dissolve or weaken rock minerals. Biological weathering results from the actions of plants, animals, and microorganisms that break down rocks through physical or chemical means.
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 oxygen cause the chemical weathering of a rock?
Oxygen can react with minerals in rocks, such as iron, leading to oxidation reactions that break down the mineral structure. This process, known as oxidation, weakens the rock and can cause it to crumble or disintegrate, contributing to the chemical weathering of the rock.
Is decaying plants dissolving minerals in rocks mechanical or chemical?
Decaying plants dissolve minerals in rocks through chemical weathering. As organic acids are released during decomposition, they react with minerals in the rock, causing them to break down chemically. This process contributes to the overall weathering and erosion of the rock over time.
What is three ways in which weak acids can cause chemical weathering of rock?
Weak acids can cause chemical weathering of rock by reacting with minerals in the rock, leading to dissolution and release of ions into the water. This can weaken the structure of the rock and make it more prone to erosion and breakdown. Additionally, weak acids can contribute to the formation of new minerals through processes like hydrolysis or oxidation, further altering the composition and stability of the rock.
How do mosses and lichen cause chemical weathering?
By they acid in the substances it weathers the rock away.
