Convergent boundaries
First, we will start off on Convergent boundaries. Convergent boundaries are created when two plates come together- also known as converging. Converging means when things come from different directions to then meet. Converging boundaries, is when a crust is demolished as one of the plates are going under another. There are three different types of convergent boundaries, and I will tell you what they are...
1)Oceanic-Continental Convergence
2)Oceanic-Oceanic Convergence
3)Continental-Continental Convergence
OCEANIC-CONTINENTAL CONVERGENCE
When the Oceanic Plate is pushed into the Continental Plate
it is being subducted under the Continental Plate,(Subducted means sink)
the plate that is over-top, in this case the Continental Plate, is being lifted up to create mountains!
The place where the Oceanic plate has sunk under another plate and Into the mantle
it is called Subduction.Subduction is also the reason for volcanoes and mountains in B.C.!
The zones that are along the Oceanic-Continental Convergence, create a deep-sea Trench. A Trench is also known as a pit, and the words deep-sea would mean the trench (pit) is deep under the sea.
The high temperatures have caused rock to melt around the Oceanic Plate as it is
going under the continental.
Many trenches appear around the Pacific Ocean because of subduction.
OCEANIC-OCEANIC CONVERGENCE
When one Oceanic Plate meets another one will be subducted under the other plate in a process that is called "Deep Oceanic Trench". It also creates deep-sea trenches! The more old,dense and cold the
Oceanic Plate is,it bends and sinks into the Mantle.
Magma rises to make volcanoes when a new Crust is formed.In some cases under-sea volcanoes form.
After millions of years the already erupted lava and the volcanic particles are piled up on the ocean floor until they are reaching sea level,to create an island volcano.
Fact-Did you know that the islands of Japan and the Japan Trench were formed by Oceanic Plates converging!
CONTINENTAL-CONTINENTAL CONVERGENCE
When two Continental Plate's collide and crumple up.(Tall mountain might form).
They are too light to be subducted. It is instead pushed upward or sideways!
Earthquakes are known at these convergent boundaries but volcanoes do not form
because they lack the subduction (little to none).
