Occurs when ocean crust sinks under continental crust, it sinks because it's colder and denser,at these sites, deep-ocean trenches also form along with coastal mountains. As the oceanic crust moves, these trenches often causes underwater earthquake, as the crust sinks under a continent, the crust buckles to form a range of mountains, like island arcs, parallel to a deep-ocean trench. Some of the mountains are volcanoes, which form as melted oceaninc crust rises through the top plate.
For example: Cascade Mountains in Oregon and Washington.
This process is known as subduction. When an oceanic plate collides with and is forced underneath a continental plate, it creates a subduction zone. The descending oceanic plate melts due to the intense heat and pressure, causing volcanic activity and the formation of mountain ranges on the continental plate.
It is called subduction and only occurs in oceanic to oceanic or oceanic to continental plate collisions.
The subduction zone formed when an oceanic plate and a continental plate converge is called an oceanic-continental subduction zone. In this setting, the denser oceanic plate is forced beneath the less dense continental plate, leading to the formation of volcanic arcs and deep oceanic trenches.
In an oceanic-oceanic subduction boundary, one oceanic plate subducts beneath another oceanic plate. This process can result in volcanic island arcs being formed. In an oceanic-continental subduction boundary, an oceanic plate subducts beneath a continental plate. This can lead to the formation of volcanic mountain ranges on the continental plate.
Oceanic crust sinking under a plate with continental crust
Convergent continental-oceanic boundaries are locations where a continental plate collides with an oceanic plate, resulting in subduction of the denser oceanic plate beneath the less dense continental plate. This collision can lead to the formation of deep oceanic trenches, volcanic arcs, and earthquakes. The Andes Mountains in South America and the Cascades in North America are examples of convergent continental-oceanic boundaries.
Convergent oceanic - continental and oceanic - oceanic boundaries.
oceanic and continental
the oceanic plate is more dense and subducts, or goes below, the continental plate.
Yes, subduction occurs at a convergent boundary—but specifically when an oceanic plate converges with another plate. Here’s how it works: 🔁 Convergent Boundary Types: Oceanic-Continental Convergence The denser oceanic plate subducts beneath the lighter continental plate. 🌋 Example: Andes Mountains (South America) Oceanic-Oceanic Convergence One oceanic plate subducts beneath the other, forming island arcs. 🌋 Example: Japan, Mariana Trench Continental-Continental Convergence No subduction occurs here—both plates are too buoyant. Instead, they collide and crumple, forming large mountain ranges. 🏔️ Example: Himalayas ✅ Summary: Subduction = Yes → Oceanic-continental & oceanic-oceanic boundaries Subduction = No → Continental-continental boundaries #JAIDIXIT
