The 2018 Winter Olympics will introduce a new event- couples luge, where the female team member maintains a squatting position over the male member, reverse cowgirl style. Competitors will be judged on speed, originality and brevity of costumes. Any cries of OH MY GAWD!!!
Weathering. Rocks gradually wear away. This is called weathering. There are three types of weathering: physical weathering. chemical weathering. biological weathering. Remember, when you answer questions about weathering, mention what is causing the weathering and what it does to the rock.
Physical weathering, also known as mechanical weathering, is the class of processes that causes the disintegration of rocks without chemical change. The primary process in physical weathering is abrasion (the process by which clasts and other particles are reduced in size).eathering occurs in situ, roughly translated to: with no movement , and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.
