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.
Spheroidal weathering is a form of chemical weathering that affects jointed bedrock and results in the formation of concentric or spherical layers of highly decayed rock within weathered bedrock that is known as saprolite.pheroidal weathering is the result of chemical weathering of systematically jointed, massive rocks, including granite, dolerite, basalt and sedimentary rocks such as silicified sandstone. It occurs as the result of the chemical alteration of such rocks along intersecting joints.
