Boundary
There are three types of boundaries:Transform boundary, Divergent boundary, and Convergent boundary. They all are different and occur in different places in the world. All boundaries can create a volcano except for the Transform boundary. But all boundaries can create a mountain.

**Convergent Boundary**
The convergent boundary happens when two plates collide together slowly over time. An example of a convergent boundary is the subduction of the Nazca Plate under the South America to make the Andes. This usally happens at a deepness of about 70 to 80 miles below the Earth's surface.Volcanoes are formed close to the collusion. When two plates having continental crust collide, they're both are too light to sink. In this case, a continent collision occurs, making large mountain ranges.An example of this is the Himalayas.

Divergent boundary
Divergent Boundary is when two plate seperate from each other.Over millions of years, tectonic plates move many hundreds of kilometers away from both sides of a divergent plate. Divergent boundaries can make fault zones in the oceanic ridge system. The origin of new divergent boundaries at triple junctions is sometimes thought to be associated with hotspots.Divergent boundaries can produce rift valleys.



Transform Boundary
Transform boundary also called transform faults are when two plate slowy slide by each other feeling like an earthquake.Transform boundaries are the only type of strike-slip fault that can be classified as a plate boundary. Transform faults show up on the seafloor as valleys that may be even deeper than the rift valleys of spreading ridges. Most transform boundary are hidden in the deep oceans. An examples of an transform boundary is the mid-oceanic ridge transform zones which are in Atlantic Ocean between South America and Africa.
