Chemical Weathering
chemical
Arkose is formed from the weathering of feldspar-rich igneous metamorphic granitic rocks. They are usually composed of quartz and feldspar called 'grus'.
A. dissolution of calcite B. breaking down of feldspar to form clay C. splitting of a rock along a fracture D. rusting of a nail E. All are examples of chemical weathering *I have read the book and researched I need help finding this please. I wouldn't be asking if I didn't knew... no rude answers*

The clay mineral Kaolinite - Al2Si2O5(OH)4.
chemical weathering of orthoclase feldspar
Feldspar breaks down giving us Al, Si and O in solution. You also get clay minerals left behind.
It reacts with The minerals in The rocks, such as in feldspar.
Feldspar minerals comes in a variety of colors and chemical formulas. The most common pink feldspar is orthoclase.
