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.

∙ 14y agothe water will naturally wear away a surface by corrosion. but it could wear it away chemicaly by pollution and things of that sort

What are some physical examples of weathering and erosion?
There is freeze thaw action which mainly occurs in very cold climates(which reach below 0 degrees celsius). What happens is water gets into the cracks in the rocks during the day and feezes at night. Since water expands when it freezes is causes the crack to get bigger and bigger. This goes on and a section of the rock breaks off. Also there is insulation. this occurs in cliates like a desert where it is hot during the day and cold at night. The surface of the rock heats up and expands slightly during the day but cools down and cotracts slightly at night. This is repeated and layers of the rock begin to peel off like an onion. There is also another type called salt crystallization. This occurs in dry climates where the temperature averages 26 to 28 degrees. Any salt crystals in the rocks expands to almost 300% their orignal size and will break up the rock. Finally there is one called pressure release. During erosion rocks may be removed from on top of other rock. The rocks that were removed exerted some pressure on the rocks underneath and when they are removed the rocks expand causing cracks is the rock. These cracks can then be made larger by the other forms of weathering Abrasion {apex}
What aids in the weathering and transportation of rocks?
Very simply, rocks on the surface of the earth are weathered and eroded. The broken pieces are carried away, mostly by streams and rivers - this is transportation. When the river drops the pieces of rock, often when it reaches the sea, we have the material to start the formation of new sedimentary rocks. Weathering also exposes more older rock, so the processes continue.
What are China's three major rivers?
The Chang River (Yangtze River), The Huang River (Yellow River), and the Xi River.
The diverse physical features of land have immense future possibilities of development Why?
Physical features of land include such things as plains, hills, mountains, rivers, lakes, swamps, etc. Each of these can be developed in different ways. Perhaps you have a farm on the plains, a mine in the hills, a ski resort in the mountains, a fishing industry on the river, etc.
How can islation lead to formation of new species?
Allopatric Speciation (geographic isolation) can lead to the formation of a new species because the population is split in two smaller populations by a physical barrier (river, canyon, mountain...).
How can a river cause chemical weathering?
acidic water.
What is physical weathring and Chemical weathring?
Physical weathering is different from chemical weathering because physical weathering is when a river is to weather away the rock. Chemical is when acid precipitation is too dissolve the rock.
How do phosphorous and nitrogen move from land into the ocean?
Phosphorus: Chemical weathering and physical weathering are two types of weathering involved in the phosphorus cycle. In chemical weathering, a chemical reaction causes phosphate (A phosphate is a salt of phosphorus acid) rocks to break down and released by lichens can cause chemical weathering. In physical weathering, processes such as wind, rain, and freezing release particles of rock and phosphate into soil. However, most phosphate in run-off settles on lake and ocean bottoms and will not enter the biotic community unless the sediment is disturbed.Nitrogen: Excess nitrate and ammonium that are not taken up by plants mix with rainwater and are washed from the soil into the ground water and streams. This unused nitrogen may settle to ocean, lake, or river bottoms in sediments. Eventually, these sediments will form rock and the nitrogen will not be available. Only after centuries of weathering will the nitrogen be released into the water.
What are 2 examples of mechanical and chemical weathering?
One example of chemical weathering is acid rain another is acid fog. An example of mechanical weathering is water eroding away mountains or water creating a river. by.....
What are characteristics of mechanical weathering?
Mechanical weathering is when rocks are worn away by physical action, ex: a river running past.
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.
Does chemical weathering occur faster in deserts than in rain forests?
Chemical weathering? No, this happens faster in rain forests. Water is an excellent solvent, and will dissolve a LOT of different materials. The primary form of weathering, however, is physical. Running water will wear away nearly ANY substance, given enough time. The Grand Canyon was created by what is now the Colorado River, wearing away the dirt and rock. You can have physical weathering in the deserts as well; think "sandstorms". Blowing sand can destroy nearly anything.
Chemical weathering is probably faster along the Amazon River then in the Himalayas true or false?
TRUE!
Is a glacier melting into a river a chemical or physical change?
yes

What is the breaking apart if rocks without changing their chemical make-up?
It is mechanical weathering, like a rock being tumbled by a river.
