What Climate Affects Chemical Weathering Of Granite

Draw a conclusion as to which rock type is more resistant to weathering in a humid climate.

What climate affects chemical weathering of granite.

This causes the limestone to dissolve. A gravestone made of granite will therefore resist fracturing cracking and chipping longer than a sandstone marker found in the same location. Chemical reactions proceed more rapidly at higher temperatures. Climate is determined by the temperature of a region plus the amount of precipitation it receives.

Carbon dioxide from the respiration of animals and ourselves is one cause of increased carbon dioxide in the atmosphere. Rainfall and temperature can affect the rate in which rocks weather. Chemical weathering alters the composition of the rock material toward surface minerals such as clays. Granite is extremely hard and less affected by the freeze thaw cycle the forces of abrasion and the surface exfoliation processes that are all a part of physical weathering.

It attacks minerals that are relatively unstable in surface conditions such as the primary minerals of igneous rocks like basalt granite or peridotite. High temperatures and greater rainfall increase the rate of chemical weathering. A region s climate strongly influences weathering. However chemical and physical weathering often go hand in hand.

Weathering therefore occurs more slowly in granite than in layered sedimentary rocks. Rank from slowest to fastest. Climate influences weathering over short and longer periods of time. Weathering is the breakdown of rock by physical chemical or biological processes.

Physical weathering also called mechanical weathering or disaggregation is the class of processes that causes the disintegration of rocks without chemical change the primary process in physical weathering is abrasion the process by which clasts and other particles are reduced in size. List the products of chemical weathering of each of the minerals in each of these rocks. Chemical weathering studies are of fundamental importance for several reasons. Chemical weathering of rocks is a spontaneous i e irreversible thermodynamic process leading to a more stable state for natural materials under a given set of conditions e g temperature and pressure.

This weathering takes place naturally through the process of physical weathering and in the form of chemical weathering which involves rain snow and other precipitation with synthetic compounds. Chemical weathering increases as. It results from the reaction of aqueous acidic and oxidizing solutions with the minerals in rocks and soils. Rank the rocks in order of the rate of chemical weathering they would experience assuming they are all located in the same warm wet climate.

Limestone areas are predominantly affected by chemical weathering when rainwater which contains a weak carbonic acid reacts with limestone.
