Oct 04 2010 Chemical weathering can also result from exposure to water. Hydrolysis occurs when silicate minerals react with water so that the mineral recombines with the water molecule to form a new mineral.For example consider the mineral potassium feldspar. Potassium feldspar is a fairly common mineral and can be found in igneous metamorphic and sedimentary rocks.

Dec 08 2021 Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil which turns into a weak acid. This slowly dissolves out the limestone along the joints bedding planes and fractures some of which become enlarged enough to form caves.

When the organism dies the remains can accumulate to become sediment or sedimentary rock. Among the types of rock produced by this process are Biochemical Limestonecalcite CaCO 3 is precipitated by organisms usually to form a shell or other skeletal structure. Accumulation of these skeletal remains results in a limestone.

For instance limestone often breaks down because of carbonation. The sulfuric acid in acid precipitation reacts with the limestone. This replaces the rock with a new chemical product called calcium bicarbonate Ca HCO 3 2. Oxidation also causes chemical weathering. Oxygen in the air reacts with chemicals in different landforms.
