Divergent:
Almost all the Earth's new crust forms at divergent boundaries, but most are not known because they lie deep under the oceans. These are zones where two plates move away from each other, allowing magma from the mantle to rise up and make a new crust.
Convergent is collision of two plates. A collision of a less dense continental plate with a more denser oceanic plate collides with a continental plate and the ocean plate goes under the continental plate. This takes a great deal of energy and results in the melting the continental crust, vulcanism occurs.
Transform:
here two plates slide by one another in opposite directions. The two plates slides by one another along a large scale fault. Since these are two large pieces of rock, there is a great deal of frictional coupling that occurs. Sometimes the plates get locked in some local region and great deal of strain energy is stored in that region. Eventually, the strain energy builds up to the point where the it is suddenly released which creates a large scale earthquake.In a transverse wave the particle displacement is perpendicular to the direction of wave propagation. one-dimensional transverse plane wave propagating from left to right. The particles do not move along with the wave; they simply oscillate up and down about their individual positions as the wave passes by.
There are some other names used for some of these.
