![]() Transform plate boundaries are called conservative boundaries. National Park Service lands contain not only active examples of all types of plate boundaries and hotspots, but also rock layers and landscapes that reveal plate-tectonic activity that occurred in the distant past. transform plate boundaries in oceans are smaller localized areas where plates scrape past each other near a larger divergent boundary Divergent plate boundaries are often called constructive boundaries and convergent plate boundaries are often called destructive boundaries. Transform plate boundaries are where plates slide laterally past one another, producing shallow earthquakes but little or no volcanic activity.Īnother large-scale feature is a hotspot, where a plate rides over a rising plume of hot mantle, creating a line of volcanoes on top of the plate.At a convergent plate boundary, one plate dives (“subducts”) beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate.Plates rip apart at a divergent plate boundary, causing volcanic activity and shallow earthquakes.There are three types of tectonic plate boundaries: The landscapes of our national parks, as well as geologic hazards such as earthquakes and volcanic eruptions, are due to the movement of the large plates of Earth’s outer shell. Katmai National Park and Preserve, Alaska. Since the plates on either side of a transform boundary are merely sliding past each. Active subduction along the southern Alaska coast has formed a volcanic arc with features including the Katmai caldera and neighboring Mount Griggs. Places where plates slide past each other are called transform boundaries. ![]()
