The theory of plate tectonics was developed by
alfred wagner in 1912. the theory of plate tectonics was developed to
explain various geologic activities, such as continental drift,
volcanos, earthquakes, and the formation of islands. the theory
hypothesises that the earth's crust is made up of tectonic plates that
move around and interact with eachother. these aformentioned
interactions are what cause volcanoes, earthquakes, continental drift
and islands to form. the theory classifies the boundries in several
ways; as divergent boundries, as convergent boundries, and as transform
A divergent boundrie is when two tectonic plates are forced apart by
magma. as the magma bubbles up, it cools, and forms new land.
where one plate is forced under the other. as it goes under, the edge
of plate melts and forces it's way up though the "opposing" plate and
forms volcanes or islands.
where one plate is forced up over the other, forming mountains or
where two plates grind against each other, creating friction. along the
boundry it builds up energy, untill the friction cannot contain it any
longer. then the energy is released, creating earthquakes.
