Chemical Weathering
qThe precipitation process in the atmosphere
dissolve and remove CO2 from the atmosphere.
qRocks exposed at Earth’s surface undergo chemical attack
from this rain of dilute acid.
qThis whole process is known as chemical
weathering.
qThe rate of chemical weathering tend to increase as
temperature increases.
qWeathering requires water as a medium both for the
dissolution of minerals and for the transport of the dissolved materials to the ocean
č The rate of chemical weathering increases as
precipitation increases.
