What are convertgent boundaries?
A conversion boundary is a place where 2 tectonic plates are mving toward each other. There are 3 types of convergent boundaries OCEANIC CRUST-OCEANIC CRUST OCEANIC CRUST-CONTINENTAL CRUST CONTINENTAL CRUST-CONTINENTAL CRUST They are classified according to their crust
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
Is the crust formed or destroyed at a sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
Is the crust formed or destroyed at the sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
What happends when 2 plates carring continental crust collide?
When two plates carrying continental crust collide, the continental crust is too light to subduct beneath the other plate. Instead, the plates crumple and fold, leading to the formation of mountain ranges. This process is known as continental collision.
What is the other type of crust the continental crust and what?
Oceanic Crust

Are the Andes fold mountains?
Yes, Fold mountains are actually formed by crust which have been uplifted and folded by compressional forces. This occurs along convergent plate boundaries where 2 plates move towards each other, between continental plates or between an oceanic and a continental plate. The crust and the rocks get bent and crumpled, and massive layers of Earth's crust gets uplifted as a result, forming spectacular fold mountains this is how the Andes are formed.
What is caused when plates collide into each other?
When plates are actually coming towards each other, there can be two different boundaries: collision and destructive boundaries. In a collision boundary, there are earthquakes, and fold mountains are created from the plates pushing up against each other, like the Himalayas. When there is a destructive boundary, like the Eurasian and Pacific plates, the oceanic plate slides underneath the continental plate, being destroyed and causing earthquakes and volcanic eruptions. There are two other types of boundaries: conservative, where plates slide past each other, and constructive, where plates move away from each other.
What main mineral makes up the continental crust?
The main mineral that makes up the continental crust is feldspar. It is one of the most abundant minerals in the Earth's crust and is commonly found in granite and other rocks that make up the continental crust.
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.
Why does the oceanic crust go under the continental crust when they collide?
Oceanic crust is denser than continental crust because it is composed of mafic rocks like basalt, whereas continental crust is made of felsic rocks like granite. This density difference causes the oceanic crust to subduct under the less dense continental crust when they collide at convergent plate boundaries.
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
Is the crust formed or destroyed at a sliding boundary?
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
Is the crust formed or destroyed at the sliding boundary?

What happens when two pieces of continental crust run into each other?
When two pieces of continental crust collide, they typically buckle and deform due to the immense pressure. This can lead to the formation of large mountain ranges, such as the Himalayas when the Indian Plate collided with the Eurasian Plate. The collision can also cause earthquakes and volcanic activity as the crust adjusts to the forces involved.
Do tectonic plates consist of continental or oceanic crust?
Tectonic plates consist of both continental and oceanic crust. The Earth's lithosphere is divided into several large and small plates that constantly move and interact with each other. Some plates are predominantly made up of continental crust, while others are mostly composed of oceanic crust.
