GENERAL GEOLOGY

Detailed explanation-1: -Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth’s mantle. Seafloor spreading creates new crust.

Detailed explanation-2: -Oceanic-continental subduction occurs when an oceanic plate dives below a continental plate. These regions can have powerful earthquakes along the subduction zones, potentially generating tsunamis. This boundary has a trench and mantle wedge, but the volcanoes are expressed in a feature known as a volcanic arc.

Detailed explanation-3: -The oceanic plate is denser, so it undergoes subduction. This means that the oceanic plate sinks beneath the continent, forming a deep ocean trench. As the oceanic plate sinks, the heat causes rock to melt, forming magma that rises through the overlying continental crust.

Detailed explanation-4: -When an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. This process is called subduction. A deep ocean trench forms at this subduction boundary.

Detailed explanation-5: -Subduction is a significant geological process involving plate tectonics. The product of convergent boundaries, subduction involves the movement of an oceanic plate into the mantle where it meets a continental or another oceanic plate. The area where subduction occurs is called a subduction zone.
