where does subduction occur?

Answer 1

In geology, a subduction zone is an area on Earth where two tectonic plates meet and move towards one another, with one sliding underneath the other and moving down into the mantle, at rates typically measured in centimeters per year. An oceanic plate ordinarily slides underneath a continental plate; this often creates a zone with many volcanoes and earthquakes. In a sense, subduction zones are the opposite of divergent boundaries, areas where material rises up from the mantle and plates are moving apart.

Divergent boundaries
The Great Rift Valley in eastern Africa
The Mid-Atlantic Ridge system separates the North American Plate and South American Plate in the west from the Eurasian Plate and African Plate in the east
The Gakkel Ridge is a slow spreading ridge located in the Arctic Ocean.

[edit] Subduction zones
The oceanic Nazca Plate is being subducted under the continental South American Plate at a rate of 10 cm per year.
The Pacific Plate is being subducted under the Eurasian and Philippine Plates.
The Pacific Plate is also being subducted under the Indo-Australian Plate north and east of New Zealand, but as this map (109 KB jpg) illustrates, the direction of subduction reverses south of the Alpine Fault where the Indo-Australian Plate starts being subducted under the Pacific Plate.
The Cascadia subduction zone is where the oceanic Juan de Fuca plate is being subducted under the continental North American plate.

Where Does Subduction Occur

Answer 3

You are PLAYING us so we will do your homework. I checked your questions and apparently your current classes are in Geology or Earth Science.

When tectonic plates are moving toward each other, something has to give. One will slide under the other. These are convergent plate boundaries. Eventually, pressure will build and an earthquake will occur. Subduction is one plate sliding under another.

Answer 5

Only when an oceanic plate dives under a continental plate. Continental plates are comprised mainly of silica, rather than oceanic plates which contain far more mafic minerals that make it heavier. That means continental plates "float" and would never ever subduct. Oceanic plates subduct.

Answer 6

subduction occurs where 2 continents meet
