Examples of ocean-continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Mountains and the Peru Trench) and subduction of the Juan de Fuca Plate under North America (creating the Cascade Range). The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another. It's a ring covering 15 countries which include New Zealand, Papa New Guinea, Indonesia, Philippines, United States, Japan, Chile, Canada, Russia, Guatemala, and Peru. The characteristics that describe convergent boundaries are subduction, where one plate sinks under another, and collision, where two plates crash together. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. It has been suggested that the next supercontinent will form in 200-250 million years, so we are currently about halfway through the scattered phase of the current supercontinent cycle. This type of boundary is not as well understood as the others. Three examples of convergent plate boundaries are: The three types of convergent plate boundaries are continental-continental, continental-oceanic, and oceanic-oceanic. What processes happen at convergent continental zones? When tectonic movements cause two tectonic plates to approach each other at the convergent plate boundary, deposits of sedimentary and metamorphic rocks at such boundaries often crumple and fold to form mountains called fold mountains. Example Of Continental Continental Convergent Boundary Volcanoes are formed at three locations on the crust of the Earth: at convergent boundaries, divergent boundaries, and hot spots. Ch 5 Flashcards | Chegg.com What are two examples of this type of plate boundary? The Himalayas are the biggest and tallest mountains in the world, and they formed from the collision between two continental plates -- the Eurasian Plate and the Indian Plate. The volcanoes located in the Pacific Ring of Fire and the Mount Etna volcano on the east coast of Sicily were formed in this manner. Here the oceanic plate of Juan de Fuca is subducting beneath the North American continental plate that is moving in a westward direction. A) westward movement of South America over the (subducting) Nazca plate. Just like these cracked pieces of eggshell, the entire outer crust of the Earth is broken down into sections, called tectonic plates. For example, watch .

The last supercontinent, Pangea, formed around 310 million years ago, and started breaking up around 180 million years ago. Harmony High School. This makes it descend or get subducted under the Caribbean Plate. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. The plate collisions that occur in these areas can produce earthquakes, volcanic activity, and crustal deformation. The collision of this oceanic and continental plate was how the Andes Mountains were formed. 55) The East Africa Rift Valleys are an example of _____ plate boundary. C) entire earth had polar conditions at the . What would happen if one of the "plates" was less dense than the other? Convergent Boundary. It has a length of about 40,000 kilometers. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Even though this boundary involves the same type of lithosphere, one of the plates will still subduct beneath the other. Oceanic-Continental Convergence. This is how mountain ranges form, including even the biggest ones in the world, like the Himalayas. In the early stages of this type of boundary, the cones will be deep beneath the ocean surface but later grow to be higher than sea level. 2 : an encounter between particles (such as atoms or molecules) resulting in exchange or transformation of energy. In order for a collision to be successful by resulting in a chemical reaction, A and B must collide with sufficient energy to break chemical bonds. As the oceanic plate descends, it is forced into higher temperature environments. Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. Examples of continent-continent convergent boundaries are the collision of the India Plate with the Eurasian Plate, creating the Himalaya Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of ranges extending from the Alps in Europe to the Zagros Mountains in Iran. The Appalachian Mountains resulted from ancient convergence when Pangaea came together. Here the Nazca Plate is subducting beneath the South American plate. However, you may visit "Cookie Settings" to provide a controlled consent. The Himalayas in Nepal, the European Alps and the Southern Alps in New Zealand are all examples of continental-continental convergent boundaries. Chemistry, 21.06.2019 17:40 . These mountain ranges are located in South America. The different ways the pieces move are like the three types of boundaries: A convergent boundary is a location where two tectonic plates move towards each other. At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate. There are also other types of boundaries, including divergent, where plates move apart. Tectonic Plate Boundaries. We have a new and improved read on this topic. The cracks in the egg are boundaries between plates. It is composed of several layers, not including the overlying sediment. What famous mountain range is formed from a continental to continental 5 Convergent Boundary Examples - The Boffins Portal Continent-continent convergence creates some of the worlds largest mountains ranges. In a subduction zone, the plates colliding can push the less dense plate upwards, forming mountains. PHESCh09.pptx - Prentice Hall EARTH SCIENCE Tarbuck Lutgens The Red Sea is an example of a more completely developed rift. The Himalayas (Figure below) are the world's tallest mountains. This is the most famous boundary because its the most active seismic area in the world. This cookie is set by GDPR Cookie Consent plugin. Now that we know what tectonic plates mean, we can easily answer the question of what a convergent boundary is. Along the Pacific Northwest coast, for example, oceanic plates subducting beneath the North American Plate create the Cascadia Subduction Zone, fueling the Cascade Range volcanoes; the Nazca (and, to a lesser extent, Antarctic) plate subducting under the South American Plate, meanwhile, uplifted the Andes and peppered that towering range with volcanoes. The Juan de Fuca oceanic plate is subducting beneath the westward moving North American Continental plate. Although they can generally be found under land or water respectively, continental and oceanic plates are actually categorized by their geological makeup. Convergent boundaries between continental plates are a bit different than oceanic/oceanic and oceanic/continental mashups. His primary interests from both a fieldwork and writing perspective include landscape ecology, geomorphology, the classification of ecosystems, biogeography, wildlife/habitat relationships, and historical ecology. In this type of convergent boundary, a powerful collision occurs. If two tectonic plates collide, they form a convergent plate boundary. C) Paleomagnetic reversals. Convergent boundaries are just one of three types of tectonic plate boundaries that can form. Magma chambers are produced as a result of this melting, and the magma is lower in density than the surrounding rock material. Evidence of Plate Tectonics | Overview, Plate Motion & Theory. At convergent boundaries that involve two continental plates, the plate tectonics is a bit more complex than in the other two types of convergent boundaries. Oceanic-Continental Convergent Boundary Fig. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". Instead, it collided with Eurasia, compressing the landscape and thrusting it upward into mountains. Necessary cookies are absolutely essential for the website to function properly. Dinosaurs lived on all of the continents. Found a content error? When two continental plates collide, the impact is so significant that the material in the subduction zone is pushed upwards. Here are 5 convergent boundary examples in real life. Continental/Continental: The Himalayas - The Geological Society Oceanography CH 2 Flashcards | Quizlet What is a real world example of convergent boundaries? When this happens, one plate usually subducts beneath the other plate, and in the case of two continental plates, the collision can be so violent that the plates merge together. The Andes Mountain Range and the south west side of South America are some of the examples of oceanic-continental boundaries. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Convergent BoundaryThis animation obsoletesee notes The subduction zone eventually becomes inactive The two continents become welded together as they are compressed together over time. Collision Zones and Mountains Instead a collision between two continental plates crunches and folds the rock at the boundary lifting it up and leading to the formation of mountains and mountain ranges. This cookie is set by GDPR Cookie Consent plugin. An example is the where the Indian sub continent collides with the Asian continent. (Confidently Correct) Reason - Each different reasoning for In fact, the collision continues to this day -- the Himalayas are still growing! The ocean floor consists of many materials, and it varies by location and depth. They create many of the mountain ranges, volcanos, and even earthquakes that occur on Earth. The pressure and friction is great enough at these boundaries that the material in the Earth's mantle can melt, and both earthquakes and volcanoes happen nearby. The amazing Himalaya Mountains are the result of this type of convergent plate boundary. Such types of convergent boundaries are also subjected to extensive faulting and folding of the rocks within the two plates that are colliding with each other.
