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.
How is weathering different from erosion? Weathering is the  breaking down of rock into smaller and smaller particles.  Weathering processes include frost wedging, acid rain dissolution,  root growth, wind particlâ¦e abrasion, heat expansion cracking,  hydraulic fracture, and rock tumbling in rivers and streams.
