can anyone describe the four diffrent types of weathering that can happen without the presence of water.?

Abrasion by wind-driven sand.\nParticle removal by wind alone.\nDecomposition and weakening due to sunlight (especially the UV).\nCracking due to temperature changes.\nThis doesn't include biological damage which can be severe due to chemicals secreted by various growths such as lichen.

Ice melting\nWater freezing\nWater boiling\nAmmonium chloride subliming

You need to think about this in terms of the question, that is what one of these processes involves movement of sediment.\n\nWeathering does involve movement of sediment, since weathering includes lots of processes that break down rocks into smaller particles or even dissolve rocks. Dissolution of limestone by carbonic acid in water is weathering that 'moves' rock. Freeze-thaw weathering of sandstone breaks the sandstone into smaller particles that are carried away by water, gravity, and wind. \n\nDeposition is the end result of the process of moving sediment, and may be the only one that does not answer your question, but because it is part of the process of 'moving' sediment it probably counts. \n\nErosion definitely moves sediment. Soil, sand, and rock are eroded by moving water and transported to new locations. \n\nAbrasion results in 'moving' sediment. Glaciers abrade underlying rock and grind it into small particles. Wind blows sand grains against rock and abrades it and reduces it to smaller particles. \n\nI think the only correct answer here is "all of the above.”

Acidic rainfall dissolves soluble rock, such as limestone.\n\nThis article has some examples and pictures of Karst topography:  http://en.wikipedia.org/wiki/Karst

1. Exfoliation caused by pressure release (tectonic)\n2. Exfoliation caused by temperature changes (heat/cold) \n3. Freeze-thaw (water)\n4. Abrasion (wind)\n5. Biological (trees, plants)\n6. Glacial plucking (gravity driven with freeze/thaw)

I agree with James again.\n\nThey help break bedrock apart in a process called mechanical weathering.\n\nTrees can also act to prevent erosion by providing wind breaks & a canopy in which to slow down the velocity of raindrops before they hit the ground.\n\nThe difference between the two is that weathering helps to create soil while erosion is the washing away of soil.\n\n:)

A complete answer to this question would require a very large book.  You will need better focus for a short answer.\n\nAcids dissolve most minerals and rocks.  Even water dissolves rocks or rock constituents over a long period of time.  There is fabulous erosion in calcium rich rocks creating tunnels and underground chambers...\n\nAcid rain enhances this process greatly.  Virtually all the salts in the oceans came by the erosion of rock salts over aeons of time spent under the never ceasing rainy seasons.\n\nSome conditions are rock forming or metamorphosing, others are rock dissolving.\n\nHeat and cold are also factors in the deterioration of rock, making it more vulnerable to water and acid rain.\n\nThere are many fabulous websites on rocks and minerals and gemstones.  Just Google some of that and you will pull up two or three super-excellent ones.\n\nTry also Googling "rock geological processes."  Keep it in quotes.

Something that requires water in order to become a true Base\n\ne.g. CaO + H2O -> Ca(OH)2

a. sugar dissolves into water and the sand can then be filtered out.\n\nb. can be distilled\n\ni'd have to look up the rest. post them when you find them, I'd like to know!

During the process of erosion, the surface of a rock is broken down.\n\nIt can be done by one or two means...\n\nMechanical weathering: rock is broken down into smaller pieces through frost wedging, abrasion, exfoliation, etc.\n\nChemical weathering: rock is broken down into one or more new substances usually through the action of water. Water reacts w/ iron to produce iron oxide. Water also reacts w/ other elements & compounds to produce mild acids that eat away at the surfaces of rocks. Most of the acids are completely natural while some are caused by pollution.\n\nBoth of these can act together to break rock down faster. When a rock has been mechanically weathered it's surface area will increase allowing the chemical weathering to occur at a faster rate.

Ok rain and snow are part of it lol. The other is springs or ground water table.\nThe water table does not go by flat land or mountains lol. It is like a sponge that is soaked up with water and you fold it wat is still there but you got low water table with it and and you got high water table with it . Kinda goes with the land construe.\nFor an example If you drill a well on low flat land you may have to go down say 90 ft. When you drill on mountain you may only have to go down 45ft.

Weathering of items implies using the natural weather to age and or blemish otherwise good items; thus increasing their hardiness, or effectiveness; some items such as leather need to be weathered to work more effectively.\n\nSevere changes within weather patterns during the weathering process can severly weaken the item being weathered.  The reason for this is that the item has to expand and contract so much that eventually it becomes spent before the process is completed.\n\nThe best way to weather an item is in a controlled environment.

First of, these are both effects caused on the surface of an object. However, weathering is an effect produced over a longer period of time as a result of a natural phenomenon whereas abrasion is an effect produced by rubbing 2 different textured surfaces together.

For it to create artesian conditions it would have to be something that has very low, or no, permeability.  In my experience this is usually unfractured limestone, mudstone, or shale.

Very complicated answer - sorry... you'll need to spend time reading these links.  the term is "erosion" - These will get you started.....\n\nhttp://www.igsb.uiowa.edu/browse/glacflds/glacflds.htm\n\nhttp://www.afrol.com/News2002/nig002_floods_erosion.htm\n\nhttp://www.mnr.gov.on.ca/MNR/water/p766.html
