Which Of Weathering Faster Granite Or Limestone

Therefore granite will weather more.

Which of weathering faster granite or limestone.

Since granite is an igneous rock this makes it highly resistant to weathering. Characteristics of rocks include texture appearance color fracture streak hardness etc. Granite vs limestone characteristics assist us to distinguish and recognize rocks. In a wet cool climate limestone will probably weather first followed by marble.

Limestone areas are predominantly affected by chemical weathering when rainwater which contains a weak carbonic acid reacts with limestone. 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. A gravestone made of granite will therefore resist fracturing cracking and chipping longer than a sandstone marker found in the same location. Though some rocks look identical they have certain characteristics which distinguish them from others.

If a diluted acid with a ph of four is used to weather limestone over a two week period then it will weather chemically faster than granite and shale because of its chemical composition. Oxidation is shown on the edge of the surface. This causes the limestone to dissolve. The proc ess is beginning to take place on the top surface of this granite headstone where a black weathering layer is de veloping.

Granite vs limestone characteristics. Weathering is the breakdown of rock by physical chemical or biological processes. Mechanical weathering is when rocks break down into smaller pieces usually caused by change in temperature or natural forces such as tree roots that grow around rocks. Which type of weathering happens to limestone faster than to other rocks.

Carbon dioxide from the respiration of animals and ourselves is one cause of increased carbon dioxide in the atmosphere. I ll say granite because the limestone as you know is faster to it s weathering. Feldspar crystals are white and will break down faster than the quartz crystals which are greyer.
