Oceanic+to+Continental

=Associated Geologic Events:=

=Locations:=

Locations would be earthquakes and volcanoes. Anything with a cause and effect for oceanic plate to continental plate.

=Associated Geologic Features:= What kinds of Geologic features are usually associated with your boundary? How were they made? Explain and use images, videos, etc to help Description: When a continental plate and oceanic plate converge the oceanic plate is subducted under the continental plate. This happens because the oceanic plate is more dense than the continental plate. These subduction zones are often known for their earthquakes, volcanos, and mountain building. This happens because the mantle makes a volcanic arc as the lighter rock is strongly subducted.

Mountain-building or orogenesis happens when large pieces of material on the plate being subducted are pressed into the overriding plate. These plate boundaries often cause earthquakes. These earthquakes happen because of the subducing plate, the mantle, volcanoes and the mountain-building which is related to arc collisions.

Above the area of a subduction zone volcanoes are in large chains that are called volcanic arcs. These volcanos often have dangerous eruptions. This is because the volcanos that form a volcanic arc have a lot of water which is from the slab and sediments. This makes the volcano have dangerous exploisons. These arcs are also sometimes rich in gold ,silver and copper.

Subduction can also result from convection in the asthenosphere. The core's heat of the earth is brought up to the mantle. This causes the mantle to convect like boiling water convects in a pan on the stove. The hot mantle that is near the core rises while the cool part of the mantle sinks. This causes convection cells to form. Continental crust usually subducts the oceanic crust because it has less dense granite unlike the basalt on the oceanic crust.
