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).
There are two types of weathering that affect the earth's surface: mechanical and chemical. Mechanical weathering is sometimes called physical weathering and often occurs because of temperature changes on the surface. For example, if enough water seeps into a crack and freezes, it expands. This causes it to work as a wedge and it slowly splits open nearby rocks.
