GEOLOGY

Detailed explanation-1: -At a convergent plate boundary, one plate dives (“subducts”) beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate; Transform plate boundaries are where plates slide laterally past one another, producing shallow earthquakes but little or no volcanic activity.

Detailed explanation-2: -Such destruction (recycling) of crust takes place along convergent boundaries where plates are moving toward each other, and sometimes one plate sinks (is subducted) under another. The location where sinking of a plate occurs is called a subduction zone.

Detailed explanation-3: -When one tectonic plate is forced under another tectonic plate, the area this occurs is called a subduction zone. This most often happens at a special type of convergent plate boundary where one tectonic plate is denser and rides lower on the mantle than the other tectonic plate.

Detailed explanation-4: -The primary subduction zone we study is the Cascadia Subduction Zone, where the Juan de Fuca Plate is sliding beneath the North American Plate. That subduction zone is largely responsible for the Cascade Volcanic Range, as well as significant earthquake and tsunami hazard for the Pacific Northwest.

Detailed explanation-5: -When two tectonic plates meet at a subduction zone and one slides underneath the other, this lithosphere material curves down into the hot mantle. This subduction process frequently occurs because of the two different types of lithosphere that make up tectonic plates: Continental and oceanic.
