This week we had a Friday 4!
1. What are the two types of weathering?
-mechanical/physical & chemical
2. What are two things that influence weathering?
-temperature and water/precipitation
3. Differentiate between the two types of weathering?
-physical/mechanical weathering changes the shape of the material where as chemical weathering changes the composition of the material
4. Provide two examples of one of the types of weathering?
physical/mechanical: frost shattering & frost heaving in the roads or up in the pass splitting rocks or trees root systems splitting rocks, or abrasion creating things like hoodoos around Kamloops
chemical: oxidation like copper turning green eg statue of liberty, rust coloured water from the iron in the soil/rock eg paint pots in Kootney National park
