Between two tectonic plates, the border is called a boundary. All the tectonic plates are constantly moving, in many different directions, all around the earth. Some move toward each other, some apart, and some slide past each other.
There are three type of plate boundaries: divergent, convergent and transform plate boundaries.
There are three type of plate boundaries: divergent, convergent and transform plate boundaries.
A divergent boundary appears or occurs when two tectonic plates part from each other and move away. Lava expels along these boundaries and superheated water is spurted from geysers. Along the rift, earthquakes occur frequently, and beneath the rift, magma (molten rock) rises from the mantle. It comes up into the gap and hardens into solid rock, this forms a new crust on the edges of the plate. Magma from the mantle then becomes solid and turns into basalt, a dark and dense rock that lies beneath the ocean floor. So, at a divergent boundary, oceanic crust is formed. Divergent boundaries also initially form rifts which eventually become rift valleys when they are in continents.
Between the African Plate and Arabian Plate in the Red Sea is where a divergent boundary lies, another example being the boundary between the Pacific Plate and the Antarctic Plate.
A convergent boundary is when to plates come together and collide. The impact of the two colliding plates bends and buckles the edge of one or both plates, and it becomes a mountain range. Volcanoes often form parallel to the boundary.
The boundary between the Eurasian Plate and the Indian Plate in the Himalayas is an example of a convergent boundary.
Subduction is the process occurs at convergent boundaries when one tectonic plate moves under another tectonic plate and sinks into the mantle as the plates come together. This process that occurs in specific regions are known as subduction zones. Times and rates of subduction are usually centimetres per year, with the average rate of convergence being approximately two to eight centimetres per year.
A transform boundary is when two plates slide past each other. Both natural and manmade structures that are caught in this sliding motion of the boundary are split into pieces and carried in opposite directions. Any rocks that lie alone the boundary are pulverised as the plates grind past each other, creating a fault valley or undersea canyon. As the plates jam against each other, they rattle the earth through a wide boundary zone, creating an earthquake.
The boundary between the Pacific Plate and the Australian Plate, crossing through New Zealand, is a transform boundary. This is the reason for New Zealand receiving so many earthquakes, because a transform boundary runs right through the centre of it. Subduction is the process that takes place at convergent boundaries by which one tectonic platemoves under another tectonic plate and sinks into the mantle as the plates converge. This occurs at regions known as subduction zones. Rates of subduction are typically centimetres per year, with the average rate of convergence being approximately two to eight centimetres per year.

As the plates jam against each other, they rattle the earth through a wide boundary zone, creating an earthquake. From these earthquakes, or sometimes large explosions and volcanoes as well, seismic waves are created. Seismic waves are waves of energy that travel through the earth's surface. The velocity (speed at which a wave travels) of these waves usually depends on the density and elasticity of it.
