What is the formation of new areas of oceanic crust which occurs through the up welling of magma?
The formation of new areas of oceanic crust occurs at mid-ocean ridges through a process called seafloor spreading. Here, magma from the mantle rises to the surface, cools, and solidifies to create new oceanic crust as tectonic plates diverge. This continuous process contributes to the expansion of ocean basins and the recycling of Earth's crust.

What is oceanic oceanic collision?
Oceanic-oceanic collision occurs when two tectonic plates carrying oceanic lithosphere collide with each other. This collision often leads to the subduction of one plate beneath the other, resulting in the formation of volcanic island arcs and deep oceanic trenches. The collision can also lead to the formation of new oceanic crust through volcanic activity.
What results when divergence occurs in the oceanic lithosphere?
When divergence occurs in the oceanic lithosphere, it leads to the formation of mid-ocean ridges where new crust is created as magma rises from the mantle and solidifies. This process is responsible for the spreading of the ocean floor and the formation of new oceanic crust.
What often occurs where an oceanic plate pushes under a continental plate?
This usually is where and how mountains ranges are formed. Volcanism can also result from the subduction melting of the oceanic crust.
Is oceanic crust slide under oceanic crust during subduction?
Yes, oceanic crust can slide under oceanic crust during subduction at convergent plate boundaries. This process occurs when a more dense oceanic plate descends beneath another oceanic plate, leading to the formation of a subduction zone.
What are 3 types of convergent pate boundaries?
Oceanic-continental plate boundary: where an oceanic plate and a continental plate collide, causing the oceanic plate to subduct beneath the continental plate. Oceanic-oceanic plate boundary: occurs when two oceanic plates collide, with one plate usually subducting beneath the other. Continental-continental plate boundary: where two continental plates collide, leading to the formation of mountain ranges through intense compression and uplifting of the crust.

What geological process occurs at a oceanic continental plate boundary?
At an oceanic continental plate boundary, a process called subduction occurs, where the denser oceanic plate is forced beneath the less dense continental plate due to the difference in their densities. This leads to the formation of deep oceanic trenches and volcanic arcs on the overriding continental plate.
What often occurs where an oceanic plate pushes under a continental plate?
This usually is where and how mountains ranges are formed. Volcanism can also result from the subduction melting of the oceanic crust.
Is oceanic crust slide under oceanic crust during subduction?
Yes, oceanic crust can slide under oceanic crust during subduction at convergent plate boundaries. This process occurs when a more dense oceanic plate descends beneath another oceanic plate, leading to the formation of a subduction zone.
What does an oceanic-oceanic convergence give rise to?
An oceanic-oceanic convergence occurs when two plates made of oceanic crust collide. This collision can lead to the formation of deep oceanic trenches, volcanic island arcs, and earthquakes. Over time, the denser plate may subduct beneath the other, leading to the recycling of oceanic crust back into the mantle.

Oceanic-oceanic plate boundary: occurs when two oceanic plates collide, with one plate usually subducting beneath the other. Continental-continental plate boundary: where two continental plates collide, leading to the formation of mountain ranges through intense compression and uplifting of the crust.
What forms where two oceanic plates collide?
When two oceanic plates collide, a process called subduction occurs, where one plate is forced beneath the other into the mantle. This often leads to the formation of volcanic arcs, deep-sea trenches, and earthquakes. Over time, the subducted plate melts and can contribute to the formation of new oceanic crust.
What is the difference between an oceanic-oceanic convergent boundary and a oceanic-continental convergent boundary?
Oceanice oceanic has a trench, which is usually the deepest part of the ocean. It also has a volcanic island. That is how Islands are found in the center of oceans. oceanic convergent has similar features but do not have islands but instead volcanic arc on the continents.
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 three different types of convergent plate boundaries?
The three types of convergent plate boundaries are oceanic-oceanic, oceanic-continental, and continental-continental. Oceanic-oceanic convergence occurs when two oceanic plates collide, resulting in the formation of volcanic island arcs. Oceanic-continental convergence happens when an oceanic plate subducts beneath a continental plate, creating volcanic mountain ranges. Continental-continental convergence involves the collision of two continental plates, leading to the formation of large mountain ranges.
What occurs when a contenintal and oceanic plate collide?
When a continental and oceanic plate collide, the denser oceanic plate is typically forced underneath the less dense continental plate in a process known as subduction. This can lead to the formation of deep ocean trenches, volcanic arcs, and seismic activity. The collision can also result in the uplift of mountains along the continental plate's edge.
