Is chemicals from plants chemical weathering or physical weathering
That is something that would show up in bold print in your text book. It's not stupid. physical chemical biological Physical weathering breaks rocks down into smaller pieces. Types of physical weathering include frost wedging, exfoliation, and thermal expansion. Chemical weathering breaks rocks down chemically adding or removing chemical elements, and changes them into other materials. Chemical weathering consists of chemical reactions, most of which involve water. Types of chemical weathering include: dissolution hydrolysis oxidation Biological weathering is the breakdown of rock caused by the action of living organisms, including plants, burrowing animals, and lichen (a crusty, rubbery, light green organic material that grows in patches on rocks as well as on wood). Lichen is a combination of fungus and algae, living together in a symbiotic relationship. Lichens can live on bare rock, and they break down rocks by secreting acids and other chemicals. The fungal part of the association secretes the acids, which react to dissolve the minerals, which are then used by the algae. Later, water seeps into the crevices etched by the acid, and assists in the breakdown through freezing (frost-wedging) and chemical weathering.
The process you are referring to is called weathering. It is the breaking down of rocks into smaller pieces by physical (e.g. water, ice) or chemical (e.g. acids from plants) means.
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.
Chemical and biological weathering are different because: a) biological weathering - this means that if a seed of a plant gets coincidentally deposited in a crack in a rock, if it is humid enough, the see will grow. it's roots will spread out and eventually break the rock. b) chemical weathering - this means that chemicals in rain/acid rain weathers away the rock.
The agents of weathering for sedimentary rocks include physical, chemical, and biological processes. Physical weathering involves the mechanical breakdown of rocks through temperature changes, freeze-thaw cycles, and abrasion. Chemical weathering alters the mineral composition through reactions with water, acids, and gases, leading to the dissolution of certain minerals. Biological weathering occurs when organisms, such as plants and fungi, contribute to rock breakdown through root growth and organic acid production.
Chemicals from plants can contribute to chemical weathering through processes like root exudation, where plant roots release substances that can break down minerals in rocks. Physical weathering, however, involves the mechanical breakdown of rocks without changes in chemical composition and is more likely due to factors like temperature changes and 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
The three types of weathering are physical, chemical, and biological. Physical weathering involves the breakdown of rocks into smaller pieces without changing their composition. Chemical weathering occurs when minerals in rocks are dissolved or altered by chemical reactions. Biological weathering is the breakdown of rocks by living organisms like plants or animals.
The three types of weathering are mechanical weathering, chemical weathering, and biological weathering. Mechanical weathering involves physical processes like freezing and thawing that break down rocks. Chemical weathering involves chemical processes like oxidation and dissolution that alter the composition of rocks. Biological weathering involves living organisms, such as plants or burrowing animals, that contribute to the breakdown of rocks.
There are two classifications of the weathering process - physical and chemical weathering.Mechanical or physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure.Includes: frost weathering, water weathering and heat stress weatheringChemical weathering, involves the direct effect of atmospheric chemicals or biologically produced chemicals (also called biological weathering) in the breakdown of rocks, soils and minerals. Includes: dissolving by rain water, oxidation of metals and actions by plants.
Weathering is the process of breaking down rocks and minerals on Earth's surface through physical, chemical, or biological means. Physical weathering involves the physical breakdown of rocks into smaller pieces without changing their chemical composition, while chemical weathering involves the transformation of rocks through chemical reactions. Biological weathering refers to the breakdown of rocks by living organisms such as plants and animals.
The breakdown of sedimentary rocks is primarily caused by weathering processes such as physical (mechanical) weathering, chemical weathering, and biological weathering. Physical weathering involves the mechanical breakdown of rocks into smaller pieces, while chemical weathering involves the breakdown of rocks through chemical reactions. Biological weathering is the breakdown of rocks by living organisms such as plants and burrowing animals.

Plants and animals and ice and frost
The sources of weathering include physical factors like wind, water, and temperature changes, as well as chemical factors such as acids, oxygen, and organic compounds. Biological factors like plants, animals, and microbes can also contribute to weathering processes.
Three weathering forces that help change rocks into soil are physical weathering, chemical weathering, and biological weathering. Physical weathering involves the breaking down of rocks into smaller pieces through processes like freezing and thawing. Chemical weathering involves the chemical alteration of minerals within rocks, while biological weathering involves the action of plants, animals, and microorganisms breaking down rocks.
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
