How Earthquakes Are Caused - College Essay

How Earthquakes Are Caused

When any two plates collide, some sort of activity is bound to take
place. A specific type of boundary is a convergent plate boundary. At this
type of boundary, two plates are moving towards each other. Neither plate
is subducted into the mantle.
Many things happen when plates drive into each other. Including
volcanic activity. When two continents are on the edges of plates, the land
crumples, and is deformed. There are numerous earthquakes as these
mountains are formed. When two plates with sea floor boundaries collide,
mountains do build up, but are rarely visible at the surface. At a sea
floor to continent plate boundary, the sea floor lithosphere is subducted
into the mantle, with ...

in. This, by the way,
happens at all of the convergent boundaries. After much time, pressure
builds up as the molten material churns in its chamber. It gets hotter, and
as we know from the laws of physics, heat rises due to its kinetic energy.
So, as the pressure get to be too much, the molten material goes up.
As you may already know, molten material mostly does not just come
out of a big hole in the ground. It comes out of mountains. When the molten
material is pushing up through to the surface of the land, the earth
doesn't just move apart to let it through. The igneous rock that the
lithosphere of comprised of gets pushed up with the material, forming the
mountain you see the molten lava and ash spew out of it. Once this molten
material cools, it forms more igneous rock, making the mountain larger.
So as you can see, plates cause a lot of commotion when moving
together. They deform the land, and create large mountains of mostly
volcanic attributes. And it's not gentle, but our ...
