Wipe with a clean damp cloth if dirty.
Limestone and marble weather faster than granite.
This experiment will test whether or not limestone chemically weather s faster than granite and shale.
It is also more susceptible to chemical weathering via.
Granite is more resistant physical weathering because of its large crystals b.
Limestone imported from other countries is often light or even dark red brown or black.
Differential weathering happens when softer rocks weathers away and leaves harder more resistant rock behind.
Hard rocks such as granite weather more slowly than softer rocks such as limestone.
By investigating the question does limestone chemically and mechanically weather faster than granite sandstone and shale it will help support the opinion that the rate of which limestone weathers is more rapid than that of granite sandstone and shale from abrasion and the altering of ph levels of diluted acid that will be used to show.
Limestone and marble weather faster than granite because.
Select limestone with mineral dolomite present as this type of limestone can be polished and is harder than other types of limestone.
Hypothesis 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 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.
Limestone and marble weather faster than granite because.
The mineral calcite of which marble is composed is softer and less resistant to abrasion than granite.
Limestone generally ranks at around a 3 on the scale while marble falls between 3 and 4.
A gravestone made of granite will therefore resist fracturing cracking and chipping longer than a sandstone marker found in the same location.
While marble is slightly harder and denser than limestone both rate very low on the mohs scale a rating used to measure the hardness of stones.
Granite does not react with rainwater and only weathers by physical erosion c.
Limestone has many cracks and holes that allow water to infiltrate and whether the rock.
Marble will weather more quickly.
Quartz which of the following is most resistant to both chemical and physical weathering.
