What do convergent plate boundary form?

Answer 1

Convergent plate boundaries can occur as a continental-continental, continental-oceanic, or oceanic-oceanic crust collision.

A continental-continental collisions will typically result in a mountain range formation, such as the Himalayan Mountain Range.

A continental-oceanic converging plate boundary will result in the more dense oceanic crust subducting beneath the less dense continental crust. The subduction zone leads to volcano formation from melting rock within the asthenosphere, beneath the continental crust. An example of this boundary is the west coast of the United States.

An oceanic-oceanic converging plate boundary will typically result in one oceanic slab "sliding" beneath the other, due to only slight differences in density. This may form a volcanic island arc on the ocean floor, but may not necessarily reach above sea level.

Answer 2

A convergent boundary forms when two tectonic plates collide.

Answer 3

convergent boundaries form when 2 plates collide, causing moutains to form over millions of years.
