Im only a week in, after 15 years of a bottle of wine a night. I am so tired all the time, I sleep like a log through the night, I feel bored and am stuffing my face with sugary food. But the anxiety is going away, and Im feeling a lot more positive.
Physical weathering: the group of processes, such as frost wedging and volume changes of minerals, that result in the mechanical disruption of rocks (e.g. granular disintegration, exfoliation, joint block separation, shattering by changes in temperature or pressure).
Physical weathering, sometimes called mechanical weathering, includes all the processes which break rocks apart without changing their chemical composition. Following are examples of physical weathering processes. Rock Abrasion. Rock abrasion occurs when rocks collide with one another or rub against one another. Collisions, if they are strong enough, can cause pieces of rock to break into two or more pieces, or cause small chips to be broken off a large piece.
