Which Of Weathering Faster Granite Or Limestone

In a wet cool climate limestone will probably weather first followed by marble.

Which of weathering faster granite or limestone.

Oxidation is shown on the edge of the surface. Under some weathering conditions such as a soil cover over a limestone the limestone will probably weather faster. Therefore granite will weather more. Carbon dioxide from the respiration of animals and ourselves is one cause of increased carbon dioxide in the atmosphere.

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. 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. I ll say granite because the limestone as you know is faster to it s weathering. Weathering is the breakdown of rock by physical chemical or biological processes.

The proc ess is beginning to take place on the top surface of this granite headstone where a black weathering layer is de veloping. 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. Feldspar crystals are white and will break down faster than the quartz crystals which are greyer.

Granite vs limestone characteristics. A gravestone made of granite will therefore resist fracturing cracking and chipping longer than a sandstone marker found in the same location. Characteristics of rocks include texture appearance color fracture streak hardness etc. Since granite is an igneous rock this makes it highly resistant to weathering.

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 type of weathering happens to limestone faster than to other rocks. Limestone areas are predominantly affected by chemical weathering when rainwater which contains a weak carbonic acid reacts with limestone.
