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).
Definition: Mechanical weathering is the set of various processes of weathering that break apart rocks into particles (sediment). There are five major mechanisms of mechanical weathering: 1  Abrasion is the grinding action of other rock particles due to gravity or the motion of water, ice or air. 2  Crystallization of ice (frost shattering) or certain minerals such as salt (as in the formation of tafoni) can exert enough force to fracture rock.
