An example of
chemical weathering is an acid dissolving limestone. This is because an acid is
a product of industrial and chemical processes that is used in a lot of
commercial practices. It can dissolve limestone because the main component of
limestone is calcium carbonate. Reacting
this with an acid produces a carbon dioxide gas. Water breaking rocks is an
example of physical weathering. Plant roots splitting rocks is an example of
biological weathering. Wind breaking own rock is an example of physical weathering.
