Chemical weathering can also be caused by the acids produced by some plants. The simple plant, lichen, is an example. As lichens grown on the surface of rock, an acid is produced that dissolves some of the minerals in the rock. Lichen is often called a "pioneer" plant because it is one of the first plants to grow in a rocky area.

Do lichens use chemical weathering?
Yes. Chemical weathering is performed by the fungal portion of a lichen symbiote (fungus and autotrophic plant) to anchor itself to rock and sometimes to extract minerals. The rootlike structures called rhizines excrete dilute acids.
Animal burrows dug in rock that let in water and air chemical or mechanical?
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.
What are 2 agents of chemical weathering?
Well, three things that cause weathering are plant roots, ice, and physical stress.
What are the different types of chemical weathering?
. There is Chemical, Biological and Physical Chemical is when acid rain weathers the rock Biological is when a plant grows in a rock and the plant roots grow into the rock (it breaks its way through) Physical is when something hits the rock and slowly it breaks away this more like erosion
Can chemical weathering occurs faster in deserts than in rainforests?
Yes, but very little in relation to wetter areas. Most weathering in deserts is due to mechanical weathering processes, such as plant root growth, frost heaving, and most importantly, abrasion from windblown particles.
What agents of chemical weathering produces weak acids that dissolve rock?
Plant roots
What is an agent of chemical weathering that produces week acids that dissolve rock?
The answer to this question is plant roots
What are the 2 main types of weathering?
The two main types of weathering are physical weathering and chemical weathering. Physical weathering involves water, wind and dust scraping away at rocks, while chemical weathering involves chemicals, usually acids, breaking down the rock.
Do lichens use chemical weathering?
Yes. Chemical weathering is performed by the fungal portion of a lichen symbiote (fungus and autotrophic plant) to anchor itself to rock and sometimes to extract minerals. The rootlike structures called rhizines excrete dilute acids.
Is moss chemical or mechanical weathering?
Moss is biological weathering, actually, because it involves a plant.
What could be a source of chemical weathering?
a coal fired power plant.
In type of climate does chemical weathering occur fastest?
plant roorts
In which type of climate does chemical weathering occur fastest?
plant roorts

How do living organisims aid in weathering?
Organisms can aid in both chemical and mechanical weathering. Roots of any plant will expand into rock and force it to break apart. Additionally some organisms like lichen exude acids that help to break down rock surfaces.
What is the chemical proccess by which a plant produces food?
photosynthesis
What kind of weathering does not alter the chemical composition of the rock?
mechanical weathering (by wind or water or perhaps tenacious plant roots or human activities)
