what is a source of chemical weathering?
This are each representative of the three main rock types, Limestone is a sedimentary rock Marble is a metamorphic rock Granite is an igneous rock
Carbonic acid in caves is a perfect example of chemical weathering. Limestone/dolomite is calcium and magnesium carbonate (CO3), respectively. Just add water, and you get HCO2-. The water dissolves the rock and the carbonic acid lowers the pH, making the solvent an even more potent weatherer as it continues to dissolve out the cave.
Usually dissociation occurs, in which a molecule comes into contact with an item, and exchanges one of its atoms for one of the item's atoms.
Limestone is calcium carbonate, CaCO3 Dolomite is predominantly Fe/MgCO3, but CaCO3 may be present as well
For the best answers, search on this site shorturl.im/avvM2 Limestone is a sedimentary rock composed mainly of calcium carbonate (CaCO3). It may contain considerable amounts of magnesium carbonate (dolomite) as well. Marble is a metamorphic rock resulting from regional or rarely contact metamorphism of sedimentary carbonate rocks, or metamorphism of older marble. The temperatures and pressures necessary to form marble usually destroy any fossils and sedimentary textures present in the original rock. Granite is a common and widely occurring type of intrusive, felsic, igneous rock. It is usually medium to coarsely crystalline, occasionally with some individual crystals larger than the groundmass.
