Answer to Question 1

B

Answer to Question 2

At or near the Earth's surface, rocks are exposed to low temperatures and pressures, very different than the environment that they were initially formed, and at the surface, they are attacked by atmospheric gases, water, acids, and organisms. These rocks are very unstable at the surface, in disequilibrium compared to where they were formed, so they undergo weathering to form more stable phases.
