Question

Which of the following geologic features is not associated with a convergent plate boundary?

1) Aleutian Islands, Alaska
2) the Lesser Antilles Islands in the Caribbean Sea
3) the Cascade Mountains in western North America
4) subduction zones
5) the San Andreas Fault in California

Answer 1

The San Andreas Fault in California is not associated with a convergent plate boundary; it is a transform boundary where tectonic plates slide horizontally past one another.

Step-by-step explanation:

The geological feature that is not associated with a convergent plate boundary is the San Andreas Fault in California. The San Andreas Fault is a transform boundary, which occurs when two tectonic plates slide past each other horizontally. The regions listed as options 1 through 3 and the process listed under option 4 are typical of convergent boundaries, where plates move towards one another resulting in subduction zones, earthquakes, volcanic eruptions, and mountain building. Conversely, the San Andreas Fault, associated with the Pacific and North American plates, produces significant seismic activity but does not involve subduction or the creation of volcanic island chains like the Aleutian or the Lesser Antilles islands.
