Study Notes
Important Concepts of Convergent Plate Boundaries
-
Trench
- Deep depressions on the ocean floor caused by subduction, where one tectonic plate moves beneath another.
-
Continental Volcanic Arc
- Formed at the edge of a continent; volcanic activity arises from melting crust due to an adjacent subducting plate.
-
Subduction Zone
- Specific areas characterized by the sinking of one tectonic plate beneath another, leading to geological activity.
-
Continental-Oceanic Convergent Plate Boundary
- Occurs when an oceanic plate collides with a continental plate; results in the subduction of the denser oceanic plate under the continental plate.
-
Oceanic-Oceanic Convergent Plate Boundary
- Formed when two oceanic plates collide; typically, the older, denser plate subducts beneath the younger one, leading to the creation of features like island arcs.
-
Island Volcanic Arc
- A series of volcanic islands that develops where one oceanic plate subducts beneath another, melting and allowing magma to rise to the surface.
-
Fold Mountains
- Mountains created from the collision of two continental plates that push the lithosphere upward, resulting in folded land structures.
-
Continental-Continental Convergent Plate Boundary
- Formed when two continental plates collide, creating significant geological features like mountain ranges due to the immense pressure and uplift.
