Investigating Plate Margins
Plate margins are the edges of the plates, where all the power of
nature is released in earthquakes and volcanoes. There are three main
types of plate margins: -
Spreading Boundaries
There are two types of spreading boundary
Ridges, where new rock is formed, pushing the plates apart, and Rift,
where the plates pull apart, and the earth between them sinks.
On the ocean floor the plates are spreading. All along the mid ocean
ridge, volcanic activity is pouring new lava out onto the seabed. As
it hardens, it becomes new rock, gradually pushing the crust, on
either side of it away. Another type of spreading boundary is the
African Rift Valley. As the two plates are moving apart, the earth
between them is becoming stretched. As it stretches it sinks, because
it is thinner. It is a little bit like taking a piece of gum, and
stretching it out. The pieces in your fingers stay thick, but the
piece in the middle gets thinner and thinner, as it is stretched.
Converging Boundaries
Converging (coming together) Boundaries, are where two plates are
banging into each other. What happens when they collide depends on the
type of plate they are.
In a subduction zone one plate is being pushed beneath the other. It
happens when a lighter plate hits a heavy plate. The lighter plate is
pushed under the heavier one. This often happens where continents meet
the ocean. As the lighter ocean crust is forced downwards, it takes
water with it. The water causes the rock to melt at lower temperatures
than normal. The pressure inside the earth is much greater than at the
surface, it increases the deeper you go. ...

Good jobs can be found in many ways and a lot of profit can be made,
if the area is used successfully.
Researchers and scientists have also made use of the active areas by
discovering more information on a volcano, some are even fascinated
about the magnificent explosions and are always on the look out for
the next big eruption.
As you can see many people have made different uses from active areas
and have become successful in different ways. Special warning systems
are able to prepare people in advance, so they can be safely evacuated
from the area. However, Living near a volcano can be a threat to your
life and at the end of the day it comes down to a person's own opinion
and whether they are willing to make use of the facilities that are
offered, but still be aware of the risks they are taking.
