What is the collision of a continental and oceanic plates?

Question

shearing, compression, faulting, and tension.

please tell me why also.

Answer 1

Actually it is subduction.

Since you have given four choices, I will answer compression.

Convergence of an oceanic plate with a continental plate produces subduction of the oceanic plate.  Compression will develop in this boundary. Of the two plates, the one to be subducted is the plate with oceanic lithosphere. The continental lithosphere is far less dense than the asthenosphere and will be buoyant on it, and therefore, will not undergo subduction.

Note to Georock:  I agree completely.  I am sure the questioner will appreciate the extra, valuable information .

Answer 2

a mountain

Answer 3

I agree with Curiosity, the best answer is compression, although it is much more complex than that.

A note to Curiosity...you could also have obduction resulting in overthrusts of ophiolites.

Answer 4

At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone. As the oceanic crust sinks, a deep oceanic trench, or valley, is formed at the edge of the continent. The crust continues to be forced deeper into the earth, where high heat and pressure cause trapped water and other gasses to be released from it. This, in turn, makes the base of the crust melt, forming magma.
