What Type Of Weathering Efects Granite

Igneous rocks especially intrusive igneous rocks such as granite weather slowly because it is hard for water to penetrate them.

What type of weathering efects granite. Breakdown of rock to depths of many metres induced by the chemical alteration of rock minerals by groundwater. If surface erosion is limited then weathering over thousands and hundreds of thousands of years. Plagioclase feldspar is a compound of sodium and. I know hydroylisis effects the weathering of granite but what temperaures do you need to make it occur.

K spar color is generally the principal influence on the color of granite. Chemical weathering is the breakdown of rock induced by reactions between rock minerals and groundwater. Biological activity extreme weather and agents of erosion such as water wind and ice are examples of environmental forces that influences the continuous breakdown wearing away and loosening of rocks and soils. Two of these are types of feldspar a group of silica compounds that constitute the most abundant mineral group on earth.

K spar is typically pink to red or white. Certain types of rock are very resistant to weathering. Granite is an igneous rock that injects or intrudes as magma into earth s crust and then cools. In granites potassium feldspar comes in two slightly different forms orthoclase feldspar and microcline feldspar.

Granite is extremely resistant and sandstone a little less so due to the percentage of quartz that each rock type contains. Other types of rock such as limestone are easily weathered because they dissolve in weak acids. Different rock types weather at different rates.
