Oceanic lithosphere is the main material being subducted at an ocean-continent convergent boundary.
There are two types of lithosphere: oceanic lithosphere and continental lithosphere.
Oceanic lithosphere is associated with oceanic crust, and is slightly denser than continental lithosphere. Plate Tectonics. The most well-known feature associated with Earth's lithosphere is tectonic activity.
At an ocean-continent convergent boundary, the denser oceanic plate is pushed under the less dense continental plate in the same manner as at an ocean-ocean boundary. Subduction of the Juan de Fuca Plate under North America created the Cascade Range.
Oceanic crust may collide with a continent. The oceanic plate is denser, so it undergoes subduction. This means that the oceanic plate sinks beneath the continent. This occurs at an ocean trench . Subduction zones are where subduction takes place.
There are 195 countries in the world comprises of 193 countries that are member states of the United Nations and 2 countries that are non-member observer states
