Where the leading edges of the oceanic plate encounter the margins of continental plates head on the denser oceanic crust dives beneath the lighter continental crust forming areas called?
These areas are called subduction zones. Subduction occurs when the oceanic plate is forced beneath the continental plate due to differences in density, leading to the formation of deep oceanic trenches and volcanic arcs on the overriding plate. This process is a key driver of plate tectonics and the formation of mountain ranges and volcanic activity.
What is oceanic -oceanic convergent boundary?
These are zones/areas where two lithospheric plates, involving an oceanic and a continental plate collide.
Where is the oceanic lithosphere subducted?
The oceanic lithosphere is subducted at convergent plate boundaries, where an oceanic plate meets a continental plate or another oceanic plate. This process typically occurs in areas known as subduction zones, characterized by deep ocean trenches. As the denser oceanic lithosphere sinks into the mantle, it leads to geological phenomena such as volcanic activity and the formation of mountain ranges.
What are the four lithosphere plate that consist of only oceanic crust?
The four lithospheric plates that consist primarily of oceanic crust are the Pacific Plate, the Nazca Plate, the Cocos Plate, and the Juan de Fuca Plate. These plates are mainly located beneath the world's oceans and are characterized by thinner, denser crust compared to continental plates. Their movements are responsible for various geological phenomena, including earthquakes and volcanic activity in adjacent areas.
What kind of boundary does oceanic lithosphere plunge beneath an overriding continental plate?
When oceanic lithosphere plunges beneath an overriding continental plate, it occurs at a convergent boundary, specifically a subduction zone. This process leads to the formation of features such as deep ocean trenches and volcanic arcs on the continental side. The denser oceanic plate is forced down into the mantle, which can trigger earthquakes and contribute to the geological activity of the region. Subduction zones are key areas for understanding plate tectonics and the recycling of Earth's crust.
Oceanic crust is lighter than the continental crust?
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
What is a oceanic continental convergent?
These are zones/areas where two lithospheric plates, involving an oceanic and a continental plate collide.

What happens when oceanic crust and continental crust collide?
Subduction occurs on continental boundaries because oceanic sub floor is denser and heavier than the lighter more buoyant crust. The oceanic crust slides under the continental crust areas usually on a plate boundary. This is in a recycle style mode that constantly is remaking the ocean floor. The oldest rocks on the ocean bottom are a drop in the geologic time bucket, compared to the rock ages on land.
What is the oceanic crust and continental crust?
underlies the ocean floor
What accounts for the difference in density between oceanic crust and contenetial crust?
Continental crust is made of granite, and forms the continents and areas of shallow seabed close to their shores. It is less dense than the material of the mantle, which consists of mafic rock. Continental crust is then less-dense than oceanic crust, which, due to sea-floor spreading, is hardened mantle/lithosphere.
Where do Rift zones rift valleys linear oceans and oceanic ridges features form?
They form in areas of the Earth in which continental or oceanic plates are pulling apart.
