(Answer to question 1 )  

Increased amounts of atmospheric carbon dioxide will increase the amount of carbonic acid that forms
in the atmosphere and result in an increase of chemical weathering.



(Answer to question 2 )  

In hydrolysis, hydrogen ions replace positive ions in minerals, and the released mineral ions go into
solution, changing the mineral's composition.



(Answer to question 3 )  

Water is a remarkable solvent because of the asymmetrical shape of the molecule and the difference in
charge between the two sides of the molecule. The negative side of the water molecule attracts positive
ions from a mineral, and the positive side attracts negative ions, which results in the eventual
dissolution of the mineral.



(Answer to question 4 )  

Exfoliation domes form from pressure release and are typically found in granite. Igneous intrusive
rocks form at tremendous depth and pressure. When they are uplifted, the pressure is released, and the
rock can expand. It does so along fractures called sheet joints that more or less parallel the existing
rock surface. Slabs of rock bounded by sheet joints slide off the parent rock, leaving behind a dome.
