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.
Limestone and marble weather faster than granite.
Differential weathering happens when softer rocks weathers away and leaves harder more resistant rock behind.
Talus slopes frost wedging is the major weathering process contribution to the formation of which regolith material.
Limestone imported from other countries is often light or even dark red brown or black.
A gravestone made of granite will therefore resist fracturing cracking and chipping longer than a sandstone marker found in the same location.
Marble will weather more quickly.
Granite is more resistant physical weathering because of its large crystals b.
The mineral calcite of which marble is composed is softer and less resistant to abrasion than granite.
Marble and limestone lie at the opposite end of the hardness scale from granite.
Limestone has many cracks and holes that allow water to infiltrate and whether the rock.
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.
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.
Wipe with a clean damp cloth if dirty.
Limestone generally ranks at around a 3 on the scale while marble falls between 3 and 4.
This experiment will test whether or not limestone chemically weather s faster than granite and shale.
Limestone and marble weather faster than granite because.
Limestone and marble can be dissolved by weak acids in rain.
It is also more susceptible to chemical weathering via.
Granite does not react with rainwater and only weathers by physical erosion c.
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.
Hard rocks such as granite weather more slowly than softer rocks such as limestone.
