Summary #1 (Building Up and Breaking Down)

Have you ever realized that two mountains even if they are of the same type, look very different one from another?What kind of processes may be responsable for the forming of mountains? Mountains are formed by diiferent processes for example: the folding of different rock layers by beeing squeezed together. As there are processes that are working to build up some others are working to break down such as weathering. There are two types of weathering. The growing of roots is an example of one type; mechanical weathering. The other type is chemical weathering that is the responsible of cavern formation.The final result of weathering is soil.
