The size and depth of these magma chambers can be determined by mapping the earthquake activity around them. The Continental margins consume about 28% of the area of the ocean. What processes happen at convergent continental zones? These mountains were formed as a result of the collision between the Eurasian Plate and the Indo-Australian Plate at the convergent boundary. SCIENCE 0373C0. Normally the older plate will subduct because of its higher density. Students should expect for the clay to collide together, forming a mountain range similar to those that occur when two continental plates collide. Here are 5 convergent boundary examples in real life. The continents of Africa, South America, Australia and Antarctica were originally part of a large supercontinent called Gondwanaland. Subduction Zones & Processes | What is Subduction? The visualization shows how earthquakes at this margin occur at depth, and define the slope of the subducting plate. Three examples of convergent plate boundaries are: The three types of convergent plate boundaries are continental-continental, continental-oceanic, and oceanic-oceanic. For example, watch . These deepest layers are made up of rock and minerals. Material that is liquified under the pressure is pushed upwards, forming underwater volcanoes which can create islands. Try refreshing the page, or contact customer support. As a result of this, dramatic seismic events can follow like earthquakes, volcanic eruptions, or deformation of the crust. As a result, there are no volcanoes at continent-continent collision zones. The other two zones being the deep-ocean basins and mid-ocean ridges. This is the most famous boundary because its the most active seismic area in the world. Are All Supplementary Angles Linear Pairs? In this activity, students will build a convergent boundary out of colored modeling clay. The Karakoram Range is part of the Himalayas. The thinner and denser oceanic plate usually subducts below the thicker and less dense continental plate. Continent-Continent Convergence, Formation of the Himalayas Harmony High School. This makes it descend or get subducted under the Caribbean Plate. 55) _____ A) an oceanic-oceanic divergent B) an oceanic-continental convergent C) a continental transform D) a continental-continental convergent E) a continental-continental divergent A semi-solid, such as marshmallows, slime or putty, could be used as that material and the plates could be something more solid, such as cardboard or paper, to represent the crust.

At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges. Continental vs. Continental - Plate Tectonics Both regions are vulnerable to severe earthquakes associated with this intense plate collision. The formation of volcanoes at such sites is explained below as an answer to the question: How Do Volcanoes Form At Convergent Boundaries? At a convergent plate boundary which plate subducts? You also have the option to opt-out of these cookies. There are three main types of convergent boundaries because there are two types of tectonic plates: continental and oceanic. Among the major zones of the ocean floor, the continental margin is ranked as one of the three major zones. D) poles were at the equator at times in the geologic past. The Appalachian, Ouachita, and Marathon mountains comprise a collisional mountain range formed 500 to 300 million years ago, whereas the Brooks Range is the result of a more recent continental collision.
