A convergent plate boundary occurs where two tectonic plates collide and one plate subducts under the other. This causes earthquakes and volcanoes due to pressure and melting in the mantle. When continental plates collide, large mountain ranges like the Himalayas are formed. When an oceanic plate collides with a continental one, the oceanic plate subsides under the continental plate, creating folds, faults, volcanoes, and coastal mountain ranges. When two oceanic plates collide, one plate will subduct beneath the other due to higher density, producing an island chain that grows into an elongate landmass over time.

2. What Is A ‘Convergent’ Boundary?
Aconvergentboundary,also knownas
a destructiveplate boundary, is a regionof active
deformationwhere two or more tectonicplatesor
fragments of the lithosphereare nearthe end of their
life cycle. Thisis in contrastto a constructiveplate
boundary.
As a resultof pressure,friction,and platematerial
melting in the mantle, earthquakesand volcanoesare
common neardestructiveboundaries,
where subductionzones or an area of continental
collision (dependingon the nature of the plates
involved) occurs.

3. What Actually Happens When
Continental Crusts Collide ?
During collisions between
two continental plates,
large mountain ranges,
such as the Himalayas are
formed. In other regions,
a divergent
boundary or transform
faults may be present.

4. If Oceanic Plate Collides With
Continental Plate
when an oceanic and a
continental plate collide, the
oceanic plate buckles and
begins to subside beneath the
continental plate (which is less
dense, and thicker).It creates
folds, faults (and earthquakes)
and volcanoes may (and
usually do) form, while coastal
mountain ranges also are
formed due to the compression
associated with the collision.

5. WHAT IF TWO OCEANIC PLATES
COLLIDE??
a convergent boundary
occurs between two
oceanic plates, one of
those plates will subduct
beneath the other.
Normally the older plate
will subduct because of
its higher density.The
subducting plate is
heated as it is forced
deeper into the mantle,
and at a depth of about
100 miles (150 km) the
plate begins to melt.
The magma begins
ascending by melting
and fracturing its way
through the overlying
rock material. This
produces an island
chain.With continued
development the
islands grow larger,
merge, and an elongate
landmass is created.
