What happens when oceanic crust collides with continental crust at a plate boundary

The oceanic crust is known to be more dense than the continental crust. When a plate carrying an oceanic crust collides with a plate carrying continental crust, the plate carrying continental crust becomes unable to sink under the more dense plate of oceanic crust. As a result, the plate of continental crust sinks beneath the plate of oceanic current and the process of subduction occurs.
