kiran areddy How can we make holes on rock with chemicals or acids 7/10/2011
anomonous Helped me do my homework thanks alot 5/16/2011
Sarah Singh these answers some of our questions but we need to know formulas like how anhydrite turns to gypsum eg.
CaSO4+2H2O=CaSO4+2H2O
(anhydrite) (gypsum)
I'm looking for how bauxite changes to hydrate aluminum but this search cannot provide it.I need the formula		 1/25/2011
BARKER Hydration- This is the kind of weathering in which the water ions attach themselves with the particles of other minerals present in the rock. The attachment leads to the formation of minerals, the volumes of which are more than the volumes of original minerals, thus creating a mechanical pressure, which leads to weathering.
Oxidation- This is the process where the metals present in the rock combine with oxygen and water to form oxides like goethite, hematite and limonite. These oxides make the rock weak and it consequently crumbles to form smaller rock particles. This process can also be termed rusting Dissolution- This is a process which is the common among all the methods of chemical weathering wherein the minerals combine with water and get washed away. Dissolution refers to the phenomenon wherein water or acids formed after combining with water dissolve limestone present in the rock. This dissolving of limestone gradually washes off parts of the rock and weather it visibly, causing holes and karst.
Factors that Influence Chemical Weathering		 1/18/2011
Karina Hydrolysis- The process of Hydrolysis effects the Silicate part of the rocks where the silicates are converted into clay minerals such as kaoloinite which are more stable than silicate minerals. The reaction takes place in a way that the free hydrogen and hydroxide ions of water replace the mineral ions to convert them in a solution. This conversion completely changes the structure of the mineral and the resultant is a clay mineral. Thus it can be said that the water ionizes and reacts with the rock minerals.
Carbonation- Carbonation is another process which can bring about weathering. In this process, carbon dioxide is added to the rock minerals as Carbonic Acid. The carbon dioxide part of the acid is derived from the atmosphere and the flora of that particular region. Now the acid reacts with minerals like feldspar and other minerals and dissolves them, thus resulting in weathering.

Amponsah Antony briefly discuss the process involved in chemical weathering 10/28/2010
isabella i dont get it! 10/7/2010
A Hi :) this was great information! thank you, I did credit. 8/9/2010
Maya Lev r u there Emanuelle? 3/25/2010
GRRRR needs WAY more information! SO not cool! 3/25/2010
Random Person hola. como estas?
hello. how are you?		 3/25/2010

moriya I HEART PIE ! 3/25/2010
Maya needs a picture gallary with captions so people can tell what's happening in the picture. :-() 3/25/2010
Samantha T Great website for researching. 3/25/2010
mandy i think the information you provided was really good and your pictures were excellent. the only thing i would suggest is that you put together a art gallerie of all of your photos so that when someone is trying to find just pictures they dont have to be distracted by other information. 12/13/2009
Lousine This is good but I need to find out how chemical weathering is formed 11/17/2009
ashley you need to put a couple of jokes like at least 5 10/31/2009
dylan you need more pictures 10/1/2009
Rose K its so good and easy to understand. thanks 9/16/2009
student good info. thanks 5/5/2009
andrea yo no se me gusta toddo gracias por encaniad me mucho mucho gracias de andrea adios 2/20/2009
Kennedy your info. is helpful ...but...not enuf for my project 1/16/2009
raquel very informational 1/13/2009
nini i love chemical weathering to 1/11/2009
Allison F She needs to have erosion as one of them. But I think that the other stuff that she did was great and very helpful. 9/27/2008
