Convergent plate boundaries occur where the Earth's tectonic plates collide with each other. At convergent plate boundaries, mountain-building often occurs. This is the kind of plate boundary that formed the lofty Himalayas. Alternatively, plates might dive under each other in what is called...
At some boundaries where two plates meet, neither plate is in a position to subduct under the other, so they both push against each other to form mountains. The lines where plates push toward each other are called convergent plate boundaries.3. Plates slide against each other At other ...
CONVERGENT PLATE BOUNDARIESSubduction zones are where two plates clash: an oceanic plate and a continental plate. The marine plate subducts (dives below the continental plate), forming a deep ocean trench immediately offshore. Water discharged from the subducting plate reduces the melting point of...
Convergent boundaries (destructive) occur where two plates slide toward each other to form either a subduction zone (one plate moving underneath the other) or a continental collision. At zones of ocean-to-continent subduction, the dense oceanic lithosphere plunges beneath the less dense continent; ...
Subduction plate boundaries occur when one plate is pushed beneath a second plate, thereby recycling old rocks from the Earth's surface via mixture with the Earth's mantle. By contrast, convergent plate boundaries represent regions where two or more tectonic plates push against or slide past one...
These are mostly convergent boundaries where one plate is going under another plate. As the plate moves down, the friction makes the rocks melt and become magma. This large source of magma so close to the surface makes an ideal condition for volcanic activity....

Reverse faults form where the crust shortens, such as near a convergent boundary. Reverse faults, specifically those at convergent plate boundaries, are linked to the most violent earthquakes, known as megathrust earthquakes, which account for nearly all earthquakes of magnitude eight or more. ...

volcanism and plate tectonicsStratovolcanoes tend to form at subduction zones, or convergent plate margins, where an oceanic plate slides beneath a continental plate and contributes to the rise of magma to the surface. At rift zones, or divergent margins, shield volcanoes tend to form as two oce...
