Which Of Weathering Faster Granite Or Limestone

Since granite is an igneous rock this makes it highly resistant to weathering. Though some rocks look identical they have certain characteristics which distinguish them from others. Which type of weathering happens to limestone faster than to other rocks.

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.

Which of weathering faster granite or limestone.

This greatly shows that out of the three rock samples being tested against limestone that granite will most likely show less weathering through the duration of the experiment. Under some weathering conditions such as a soil cover over a limestone the limestone will probably weather faster. 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. Granite vs limestone characteristics.

Limestone areas are predominantly affected by chemical weathering when rainwater which contains a weak carbonic acid reacts with limestone. The proc ess is beginning to take place on the top surface of this granite headstone where a black weathering layer is de veloping. Oxidation is shown on the edge of the surface. Feldspar crystals are white and will break down faster than the quartz crystals which are greyer.

In a wet cool climate limestone will probably weather first followed by marble. Characteristics of rocks include texture appearance color fracture streak hardness etc. Granite vs limestone characteristics assist us to distinguish and recognize rocks. I ll say granite because the limestone as you know is faster to it s weathering.

Carbon dioxide from the respiration of animals and ourselves is one cause of increased carbon dioxide in the atmosphere. 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. The crystals in the granite are being decomposed by hy drolysis. Weathering is the breakdown of rock by physical chemical or biological processes.

A gravestone made of granite will therefore resist fracturing cracking and chipping longer than a sandstone marker found in the same location. Therefore granite will weather more. This causes the limestone to dissolve.
