Which of the following is a geographic example of a transform fault boundary?

A transform fault boundary occurs when two tectonic plates slide past one another horizontally. The San Andreas Fault in California is a prime example of this type of boundary, where the Pacific Plate and the North American Plate are sliding alongside each other. This lateral movement can cause significant seismic activity, making it a critical area for studying earthquakes.

In contrast, the East African Rift Valley represents a divergent boundary, where tectonic plates are moving apart. The Andes Mountains are formed by a convergent boundary where an oceanic plate subducts beneath a continental plate, resulting in mountain formation. The Mid-Atlantic Ridge is also a divergent boundary, where two oceanic plates are moving away from each other, creating new oceanic crust. Each of these examples highlights different types of tectonic interactions, but the San Andreas Fault distinctly illustrates the characteristics of a transform fault boundary.
