Where two crust plates meet, there are several things which can happen. One is subduction, where one plate slips under the other plate. This can cause earth quakes, but generally happens painlessly. The deepest trenches in the ocean, deeper than Mt. Everest is tall, are the dips made when one plate goes under another as subduction. Convergent contacts are when two plates "butt heads" without subduction, causing upwards buckling of one or both plates, resulting in destructive mountain building, faulting and folding. Some of the most dramatic mountainscapes in the world- the Rockies, Andes and Himalayas, are convergent plate mountains. Divergent contacts are constructive. They occur when the two adjacent plates are spreading away from one another, making a crack in the middle. This crack allows magma to come to the surface, creating new crust in the form of volcanic islands and undersea mountains. The Mid Atlantic Ridge (and Rift Valley) is a mountain range underwater from Iceland to the tip of South America caused by magma upwelling in divergent plate boundaries. Upwelling of new crust is the engine of plate spreading, as new crust actually makes the Earth's crust bigger, crowding the plates together. Transform boundaries are areas where plates are sliding along one another, causing slow and steady pressure on both plates, resulting in slip faults like the San Andreas Fault line, which is the bugaboo of California. Small slips diffuse the energy and allow for less destructive quakes- so constant quakes are a good thing. People livng on slip or transform faults hope for constant low-grade activity, instead of one big slip. One may easily illustrate these actions by pushing together two pieces of cardboard and watching what happens. The same forces may easily be seen in miniature on a frozen lake when ice floes interact.

Forms when two Crustal Lithospheric Plates come together?

A convergent boundary is formed when two crustal lithospheric plates collide. This collision can result in the formation of mountain ranges, deep ocean trenches, and volcanic arcs. The type of convergent boundary that forms depends on the type of crust involved in the collision (oceanic or continental).


In which direction do plates travel at a convergent boundary?

At a convergent boundary, plates move towards each other.


What is the name of the boundary where two plates are moving toward one another?

Convergent boundary.


What is the difference between convergent boundary and convergent plate boundary?

Convergent means where plates are moving together. Divergent means where plates are moving apart.


What type of boundary is formed when plates collide?

When plates collide it is called a convergent boundary.newtest3


How is a transform boundary from a convergent boundary?

At a convergent boundary two plates move toward each other. At a transform boundary plates slide past each other.


What is convergent plate boundary and what are the plates doing?

A convergent plate boundary is a place where tectonic plates are moving together. The plates are sliding across the the plastic asthenosphere.


Does sea floor spreading occur at a convergent boundary?

No, sea floor spreading does not occur at a convergent boundary. Sea floor spreading occurs at divergent boundaries where tectonic plates move away from each other, allowing magma to rise and create new oceanic crust. At convergent boundaries, two plates collide, leading to subduction or crustal deformation.


What boundary is it where two plates push together?

An area where two tectonic plates collide is called a boundary. There are three kinds of boundaries. They are convergent, divergent, and transform boundaries.


What type of boundary is forward when plates collide?

convergent boundary


What plate boundary is formed when plates collide.?

Convergent boundary


What is the type of plate boundary where two plates collide?

A convergent boundary is where two plates collide. This can lead to the formation of mountains, earthquakes, and volcanic activity.
