Question
The west coast (Pacific coast) of South America is a classic example of an Amero-trailing edge continental margin. Granite is the predominant rock type of the seafloor and it has a higher density than basalt. The presence of angular sediment grains indicates extensive transport of the particles and significant chemical weathering. Faulting occurs in continental divergence zones such as rift basins. Staircase-like structures form due to tension and the resulting faults. A geographic example of where to find such features would be the Valley and Ridge province. Hot spots (mantle plumes) are only found on the interior of tectonic plates. Grain size is used to distinguish among the different types of metamorphic rocks. Mechanical weathering alters only the size and shape of a rock and not its chemistry. Hydrolysis results in rusting of minerals containing iron.Explanation / Answer
