Where does the oceanic crust begin?
The oceanic crust begins at the Mid-Ocean Ridge, where tectonic plates are moving apart, allowing magma to rise and solidify, forming new crust. This process of seafloor spreading creates the youngest oceanic crust at the ridge and older crust farther away from it.
Why oceanic crust is always subducted underneath continental crust?
Oceanic crust is denser than continental crust, so when they collide, the denser oceanic crust is forced beneath the lighter continental crust in a process known as subduction. This subduction occurs at convergent plate boundaries where two plates are moving towards each other. The sinking oceanic crust can trigger volcanic activity and create mountain ranges on the continental crust.
The process of an oceanic plate colliding with and descending underneath a continental plate?
This process is known as subduction. When an oceanic plate collides with and is forced underneath a continental plate, it creates a subduction zone. The descending oceanic plate melts due to the intense heat and pressure, causing volcanic activity and the formation of mountain ranges on the continental plate.
A location on Earth where each type of plate boundary is present?
There are three types of convergent boundaries: oceanic-oceanic, oceanic-continental, and continental-continental. An example of continental-continental is the San Andreas Fault in California. An example of oceanic-continental is the Peru-Chile Trench. An example of oceanic-oceanic is almost anywhere in the ocean. Because the tectonic plates are continuously moving, although they may be moving slowly, new boundaries are formed often. Thus, oceanic-oceanic boundaries are constantly forming. A specific example would be in the western Pacific Ocean. There is a tangle of arcs in the Indian Ocean; there's also the Caribbean and South Sandwich Island arcs.
A slab of continental or oceanic crust is known as?
A slab of continental or oceanic crust is known as a tectonic plate. These plates make up the Earth's lithosphere and float on the semi-fluid asthenosphere below, moving due to the process of plate tectonics.
Do the continental plates remain in one place?
No, both the continental and oceanic plates are always moving. Moving slowly, but always moving.
What two main names do you give to the moving plates?
continental and the oceanic.

When two geologic plates are moving away from each other what happens?
When it is two continental plates, new oceanic crust is formed, and when this continues, more oceanic crust is formed between the plates.
Do continental plates move faster than oceanic plates?
No, oceanic plates move faster than continental plates. This is due to the density of the oceanic plates (basalt is denser). For example, the fastest moving plates are the Pacific plate, Cocos plate, and Nazca plate. All oceanic.
Where does oceanic continental convergence occur country state continent?
Oceanic-continental convergence occurs in regions where an oceanic plate is subducting beneath a continental plate. Examples of this type of convergence can be found in various locations around the world, such as along the west coast of South America in countries like Chile, Peru, and Ecuador, as well as in regions like the Andes Mountains.
What does oceanic plates mean?
Oceanic plates are sections of the Earth's lithosphere that form the bedrock beneath the world's oceans. These plates are typically denser and younger than continental plates, and they are constantly moving due to the process of plate tectonics. Subduction zones are often found at the boundaries where oceanic plates meet continental plates.
What is the result when continental plates meet oceanic plates?
If the plates are moving toward each other, the more dense oceanic plate will subduct underneath the less dense continental plate. Mountain ranges and volcanism may result as the water saturated subducting oceanic crust creates molten rock which attempts to rise to the surface.
