regional metamorphism is most closely associated with which type of plate boundary?
17886
Regional metamorphism occurs when rocks are buried deep in the crust. This is commonly associated with convergent plate boundaries and the formation of mountain ranges. Because burial to 10 km to 20 km is required, the areas affected tend to be large. Most regional metamorphism takes place within continental crust.

Subduction zones exist at convergent plate boundaries where one plate of oceanic lithosphere converges with another plate. The descending slab, the subducting plate, is over-ridden by the leading edge of the other plate.

There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. Image courtesy of the U.S. Geological Survey. Download image (jpg, 76 KB).

A convergent plate boundary , also known as a destructive plate boundary , usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement can cause earthquakes. As the plates collide, the oceanic plate is forced beneath the continental plate.

Each of these types of plate boundaries is associated with different geological features. Typically, a convergent plate boundary—such as the one between the Indian Plate and the Eurasian Plate—forms towering mountain ranges, like the Himalaya, as Earth's crust is crumpled and pushed upward.

The oceanic plate pushes into the land, and coastal mountains go up. That's a standard convergent plate boundary. It doesn't explain why the highest parts of the Rocky Mountains are more than 1000 km away from the plate boundary.

In general, the deepest and the most powerful earthquakes occur at plate collision (or subduction) zones at convergent plate boundaries.

The location where two plates meet is called a plate boundary. Plate boundaries are commonly associated with geological events such as earthquakes and the creation of topographic features such as mountains, volcanoes, mid-ocean ridges, and oceanic trenches.

Another event that can occur at a convergent boundary, usually one between two plates bearing continental crust, is continental collision. When two landmasses collide, they push into each other, deforming and creating tall, folded mountains.

A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.

Movement in narrow zones along plate boundaries causes most earthquakes. Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.

There are two main mechanisms of metamorphism, heat and pressure. HEAT: There are two sources of heat, one comes from the geothermal gradient - the increase in temperature that occurs with increase in depth in the earth.

The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. At a divergent boundary, tectonic plates move apart from one another.

Divergent plate boundaries. One young divergent plate boundary that you'll recognize is actively forming the Red Sea. Although the Arabian penninsula and Africa were once linked to form a single continent, they are now being ripped apart.

The three main types are convergent, divergent and conservative. Divergent plate boundaries are where new crust is created. Mid ocean ridges are the main type. Convergent plate boundaries are where two plates collide.

Volcanoes and earthquakes are most likely to form along plate boundaries.
