Question

scientists find frequent shallow earthquakes, no volcanic activity, and plates moving horizontally past each other. which type of boundary is described? divergent subduction trench convergent transform

Explanation:

Divergent boundaries involve plates moving apart, often with volcanic activity. Convergent boundaries have plates colliding, which can create deep earthquakes and volcanoes. Subduction trenches form at convergent oceanic-oceanic or oceanic-continental boundaries. Transform boundaries are defined by plates sliding horizontally past one another, producing frequent shallow earthquakes with no associated volcanic activity, matching the description.

Answer:

Transform
