Document Summary
India has pushed a few hundred km under the asian plate this is what has uplifted the. How did continents form: early in its history earth had no continents, they have evolved over time to their current state. If we look at the geology we see the formation of cratons stable parts of a continental mass. It will now stay in the bent shape the rock now undergoes ductile deformation. If the rock is able to flex rather than break the most common thing seen are fold in the layers: usually happens deep underground at high temperatures and pressure (often metamorphic process as well) It relates to the bonding structure within the material: the weaker bonds are more likely to deform this way. Multiple faults: many faults often occur close together, multiple normal faults can results in chunks of rock being displaced these are horst or grabens.
