Geology 12 (1-2) - Weathering around WVSS by Tess Gardiner https://padlet.com/tessgardiner1/eht6q6u7j8kw -Get into groups of no more than two. -Find three different types of weathering in the nearby area and photograph it! -You cannot leave the area close to the school -For each type of weathering you discover, you must answer the following questions: 1. What type of weathering is it? 2. How can you tell? 3. What do see as being the cause of this weathering? You need to report back with your findings before the end of class. en-us 2018-02-14 20:25:16 UTC 2023-06-05 06:00:42 UTC hello@padlet.com Sam Capier https://padlet.com/tessgardiner1/eht6q6u7j8kw/wish/232141610 1. This type of weathering is Oxidation 
2. The rock has a reddy tinge look to it
3. The cause of this is the oxygen reacting to the iron in the rock

2. There are many cracks in the rocks
3. The cold freezing climate is the reason for making cracks in the rocks]]> 2018-02-15 20:34:18 UTC https://padlet.com/tessgardiner1/eht6q6u7j8kw/wish/232143605 Cooper and Ryan https://padlet.com/tessgardiner1/eht6q6u7j8kw/wish/232144304 1: Dissolution: The rock has been shaped due to acid rain
