What type of boundary is formed when two tectonic plates slide past each other?

• A. Divergent boundary
• B. Convergent boundary
• C. Transform boundary
• D. Subduction boundary

Answer: (C)

When two tectonic plates slide past each other, they form a transform boundary. This type of boundary is characterized by the horizontal movement of the plates alongside one another. As they move, friction can cause stress to accumulate, which may eventually release as earthquakes. The San Andreas Fault in California is a well-known example of a transform boundary, where the Pacific and North American plates slide past each other. This process contrasts with divergent boundaries, where plates move apart, and convergent boundaries, where plates move toward one another, often leading to one plate being pushed into another (subduction). Therefore, the correct answer emphasizes the lateral motion of the plates and how this distinguishes transform boundaries from other types.
