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).
Making the world better, one answer at a time. Mechanical weathering is physical changes that break down and/or cracks the rock, such as ice wedging, temperature changes, root growth, or animal activity. Chemical weathering is a chemical change that changes the chemicals of the substance to make a new one.
