How can plants cause chemical?
Plants are made from chemicals and they release chemicals.
What is the diffence between chemical weathering and physical weathering?
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.
How do you explain the three types of 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.
How do animals contribute to chemical weathering?
the dogs urine is acid which is a chemical and it can kill plants
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
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
What is an agent of weathering?
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.
What are three typed of chemical weathering?
Chemical(acid in rainwater dissolving limestone), biological (work of animals and plants) and physical (freeze thaw)
What is organic weathering?
Organic weathering is the breakdown of rocks by plants or animal action or by chemicals formed from plants and animals.
What item made by humans that can be broken down by the agents of physical and chemical weathering?
Plants and animals and ice and frost
. How is physical weathering different from 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
How can plants cause chemical?
Plants are made from chemicals and they release chemicals.
Acids and growth of plants' root cause which type of weathering?
chemical weathering
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.
Is chemical weathering faster along the Amazon river than the Himalayas?
Yes that would make sense as there is a great deal of vegetation along the Amazon as opposed to any place in the Himalaya's. and plants are responsible for creating many of the chemicals that result in chemical weathering.
Are plants a factor in mechanical or chemical weathering?
mechanical
Is decaying plants dissolving minerals in rocks mechanical or chemical?
Chemical Weathering
