Document Summary

Fusion takes more energy to put in than what we get out. Also you need to know how to convert units. So we can see what a barrel of oil converts to joules. Smaller surface area: more chemical weathering. (more mechanical weathering equals smaller pieaces which results in more chemical weathering) Processes which are proportional to sa: oxidation, erosion, nutrient absorption. Crust becomes exposed, less force bearing down. Biological activity- roots from trees, animal movement. In chemical weathering, water is the most important. Water coupled with whatever else is in the water. Dissolution small amount of acid in water increases corrosive force- dissolution. Hydrolysis- most important in our area as it produces clay minerals.

Clay stable on earth, not at depth. Dissassociated acids dissolve the rock when water is added. Bauxite and potassium rich minerals formed by weathering out the rest of the material.
