It creates a mountain that might turn into a volcano.
a trench is formed when 2 oceanic plates collide
1. Oceanic trenches. 2. Volcanic islands. 3. Volcanic mountains. and 4. Volcanic arcs.
the earth is made up of different plates and all the plates are different sizes, shapes and weight. there are 2 types of plates, oceanic and continental. a mountain is formed when 2 continental plates of the same weight collide into each other, it creates a mountain and the oceanic plates underneath them are pused down.
when 2 plates collide and form a "little hill "
Oceanic-continental convergence (when an oceanic plate meets a continental plate) & oceanic-oceanic convergence (2 oceanic plates) both involve oceanic plates & subduction. Continental-continental convergence (2 continental plates) involves neither.
It's referred to as a Convergent Boundary If 2 Continental Plates --> Mountains If 2 Oceanic Plates --> Subduction of Heavier (older) Plate If Continental-Oceanic --> Oceanic Plate slides under the Continental Plate (Subduction of Oceanic)
earthquakes
When two continental plates collide they buckle up and fold forming mountains.
convergence
an earth quake happens when two plates meet
It makes a mountain.
