All of the following factors are related to the plate tectonics model of the western coast of South America except the
A) presence of subduction zones.
To find out which of the factors are unrelated to the plate tectonics model of the western coast of South America, we first need to understand what the plate tectonics model entails.
Plate tectonics is a scientific theory that explains how Earth's lithosphere, which is composed of rigid plates, moves and interacts with one another. The western coast of South America falls under the influence of the tectonic activity associated with several plates, namely the Nazca Plate, the South American Plate, and the Antarctic Plate. As these plates converge and interact, various geologic phenomena occur, including volcanic activity, earthquakes, and mountain formation.
Now, to identify the factor unrelated to the plate tectonics model, we need to examine the given options. Could you please provide the factors that are mentioned?
All of the following factors are related to the plate tectonics model of the western coast of South America:
1. Subduction: The western coast of South America is a convergent plate boundary where the Nazca Plate is subducting beneath the South American Plate. This subduction is responsible for the formation of the Andes Mountains.
2. Earthquakes: The subduction of the Nazca Plate beneath the South American Plate generates frequent earthquakes along the western coast of South America. These earthquakes are a significant feature of the plate tectonics model in this region.
3. Volcanism: As the Nazca Plate subducts beneath the South American Plate, it can melt and generate magma. This magma rises to the surface, resulting in volcanic activity. The Andean Volcanic Belt is a notable feature of the western coast of South America.
Therefore, none of these factors can be excluded from the plate tectonics model of the western coast of South America.
