Document Summary
Geomorphologists attempt to understand how you get from a certain landscape to another landform (i. e. erosion/uplift) --> how the evolution changes depending on tectonic setting and climate. Landforms evolve depending on their tectonic setting and their forces (mainly their stresses = a force per unit area) Compression stress: shortening or thickening of the crust will occur --> this is by folding/reverse faulting of the crust, in a back and forth horizontal motion. Tension stress: stretching or thinning of the crust --> this is by normal faults or spreading centers. Shear stress: bending of the crust --> this is by a strike-slip fault. Transform boundaries --> forces are moving opposite of each other --> causes shearing/twisting laterally or faulting. Caused by hot partially melted rock (called magma) that is less dense/more buoyant, rises to the surface (they are generated by subduction) and then that becomes the continental crust.
