Answer:When I placed the plastic covers on top of one another, I observed that many of the markings overlapped or were closely aligned. This shows that the locations of active volcanoes, earthquake epicenters, and major mountain belts often appear in the same regions on the map.This tells us that active volcanoes, earthquake epicenters, and major mountain belts are mostly found along the boundaries of tectonic plates. These overlapping locations indicate that these natural events and formations are related to the movement and interaction of Earth's plates.
