Identify all of the true statements aboutthe South American Plate in Chile.Question 27Answeractive marginsubduction zonetransform fault boundarypassive margin
Solution
The South American Plate in Chile is characterized by:
-
Active Margin: This is true. An active margin is found on the west coast of South America, where the oceanic Nazca Plate is subducting beneath the continental South American Plate.
-
Subduction Zone: This is true. The west coast of Chile is a major subduction zone where the Nazca Plate is moving under the South American Plate. This process is responsible for the Andes mountain range and the frequent earthquakes in the region.
-
Transform Fault Boundary: This is false. A transform fault boundary is not present in Chile. These boundaries are where two plates slide past each other, such as the San Andreas Fault in California.
-
Passive Margin: This is false. The east coast of South America, facing the Atlantic Ocean, is a passive margin. However, the west coast of Chile, which is part of the South American Plate, is an active margin due to the subduction of the Nazca Plate.
