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 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 The boundary between the two plates in the past has been convergent, and most of the Greater Antilles group of islands are formed due to the complex interaction between the two plates.

They are often termed as ‘destructive boundaries’ as they cause a lot of destruction. In this case, oceanic lithosphere subducts beneath continental lithosphere. Convergent Boundary: A convergent boundary is a type of tectonic boundary that crashes into one another. Figure 3 is an example of a convergent plate boundary.

Plates rip apart at a divergent plate boundary, causing volcanic activity and shallow earthquakes For example, the arctic ridge has the slowest rate i.e 2.5 cm per year or less.

There are three types of tectonic plate boundaries: One plate eventually slides beneath the other, a process known as. Quick Tips Ocean-Continent Convergent Plate Boundaries Loading. 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. A convergent boundary is an area on Earth where two or more lithospheric plates collide. Ocean-Continent Convergent Plate Boundaries Covers ocean-ocean and ocean-continent convergent plate boundaries, including the creation of volcanic arcs and earthquakes. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate.

Examples of ocean-continent convergent boundaries are. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. At an ocean-continent convergent boundary, the denser oceanic plate is pushed under the less dense continental plate in the same manner as at an ocean-ocean boundary. Katmai National Park and Preserve, Alaska. The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. Active subduction along the southern Alaska coast has formed a volcanic arc with features including the Katmai caldera and neighboring Mount Griggs.
