What are 5 physical weathering agents?
Temperature Change Pressure Change Animal Action Wind, Water, and Gravity Plant Growth
Compare and contrast chemical weathering and mechanical weathering?
Mechanical weathering is taking a big rock and breaking it down to small rocks by releasing pressure, freezing and thawing (water and ice), animal action, plant growth and abrasion. Chemical weathering is when a rock loses it shape but STILL IS MADE OF THE SAME METRICAL. Chemical weathering uses water, oxygen, carbon dioxide, living organism, and acid rain.
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 is weathering and how it affects?
Weathering is the breaking down of rocks in situ. It acts through a variety of means, including frost shattering and ex-foliation. There are a number of different classifications of weathering, including biological, chemical and mechanical (including the aforementioned examples).Biological weathering includes the action of tree roots and animal burrowing, chemical includes chemical reactions and also corrosion due to dissolution of soluble minerals.I hope this answers your question.
What is animal weathering?
Animal Weathering is when an animal digs up the ground or smushes a hole into it. I learned this in Science. Hope this helps!!
Is animal action mechanical or chemical weathering?
Chemical weathering
When an animal rots is this a chemical change?
This is a physical action.

What is called when rocks break down without changing in chemical composition?
Mechanical weathering.
What are non-examples of mechanical weathering?
Mechanical weathering is physical changes that break down and/or cracks the rock, such as ice wedging, temperature changes, root growth, or animal activity. Chemical weathering is a chemical change that changes the chemicals of the substance to make a new one. Examples of chemical weathering include oxidation, acid rain, hydration, and carbonation.
What is an example of a physical weathering and what is weathered?
An example of physical weathering is animal actions and weathering is the process that breaks down rock and other substances of Earth's surface.

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.

Which of these type of weathering does not require the presence of water?
Since you did not specify which types of weathering you meant (necessary for this question to properly be answered), I will just summarize a bit of basic information on weathering and try to answer as best as I can in the most general sense.There are three general types of weathering: mechanical (sometimes called physical), chemical, and biological. Chemical weathering entails the alteration of the chemical and mineralogical composition of the weathered material. Physical weathering is the breakdown of mineral or rock material by entirely mechanical methods. Biological weathering involves the disintegration of rock and mineral due to the chemical and/or physical agents of an organism.Chemical types can be caused by processes that require water (such as hydrolysis, or carbonation - when there is formation of carbonic acid from carbon dioxide and water). Physical types contain processes that may not, though. For example, a type of physical weathering is abrasion, which is when there are collisions that can be caused by wind (although it can also be caused by water or ice). Sometimes biological weatheringdoes not require water - such as when particles fracture because of animal burrowing or due to pressure being exerted by growing roots.
What are the different types of weatheing?
There are two different types of weathering regarding rocks. Chemical weathering involves decomposition or dissolution of a rock. Examples of chemical weathering include halite being dissolved to form salt water and calcite decomposing to calcium and bicarbonate ions in aqueous solution. Physical, or mechanical, weathering can be cracking, scratching, crushing, abrasion, or other physical changes to rocks. Big rocks are weathered into broken pieces which can be further broken down into crystals and logs animal shells are reduced to peat and shell gravel.
