When an oceanic plate and a continental plate collide, the oceanic plate is always subducted. Oceanic plates are denser than continental plates, and they have a higher iron content. Since they are denser, oceanic plates always sink below the continental plate in the event of a collision.
Usually subduction of the denser thinner oceanic crust under the lighter thicker continental crust. This also produces a row of volcanoes in the continental crust producing lava high in water content and resulting in explosive eruptions.
Its when the oceanic crust and the continental crsut colide together.
Oceanic crust is mostly basaltic, which is denser, while continental crust is made from mostly basaltic and sedimentary rocks, which are less dense. This difference in density is why the oceanic crust sinks lower (thus the oceans) and the continental crust rides higher (thus the continents) on the mantle.
Continental crust is on top of the oceanic crust Continental crust is made of granite whereas oceanic crust is made of basalt Continental crust is partly above sea level and partly below whereas oceanic crust is always below sea level.
Most significantly, there is a material difference in the weight and density of the two types of crust. This manifests itself when tectonic movement brings oceanic in continental plates into collision. Oceanic crust is relatively denser but typically about 100km this. Continental crust is lighter but almost twice as thick--about 200km.
Continental-continental, Oceanic-oceanic and Oceanic-continental convergent boundaries.
The oceanic is heavier
compression
The material they are made of.
when two plates collide they form trenches.
the oceanic plate is less bouyant so it slides under the continental plate
Yes, the Himalayas are located on a convergent boundary.There are three types of convergent boundaries:-Oceanic-Oceanic-Oceanic-Continental-Continental-ContinentalOf the three types, the Himalayas are considered to be Continental-Continental. Meaning, it's a collision between two continental plates.
Andes - continental oceanic aleutians - oceanic oceanic North American cordillera - arc continent Appalachians - continental continental
Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt
oceanic crust is much more dense than continental crust. Oceanic crust is also responsible for the movement of continental crust.
In a head-on collision, the oceanic plate subducts into the mantle.
