Assignment Reflection

Describe the correlation is between earthquakes and volcanoes in terms of the Theory of
Plate Tectonics.
From the USGS article “Plate Tectonics and People,” it states that most earthquakes and
volcanic eruptions do not strike randomly but occur in specific areas, such as along plate
boundaries. Throughout this assignment, it has been obvious that certain natural disasters occur
in very specific areas. Most earthquakes and volcanoes are associated with areas where plate
tectonic boundaries have seismic activity occurring. Earthquakes occur along the plate
boundaries as the plates move parallel to other plates. As these plates descend into the earth they
grind and produce earthquakes which cause the hot liquid in the earth, magma to emerge upward
through volcanoes and vents. Volcanoes generally occur at areas of subduction, where one plate
is sinking below another.

Analyze the spatial relationship that exists with these forces of nature.
Their spatial relationship is because one event leads to another. Magma moving up the cone
of a volcano causes earthquakes if it has a high enough viscosity or resistance to the flow. Just
like there is a circle of life to the food chain, in a sense, there is a similar cycle with how the
earth recycles itself and the continents continue to move and make new.

Analyze the spatial distribution that exists with these forces of nature.
Both earthquakes and volcanoes happen along tectonic plate boundaries where the conditions
are just right and the earth shakes and causes earthquakes to shake the earth and volcanoes to
form. Where ever the plates meet, is where the volcanoes tend to form due to the subduction of
the plates causing magma to be produced, which in turn brings volcanoes into the equation.

Describe what you learned about earthquakes and volcanoes that you did not know
before this course
There is so much more to what brings an earthquake or a volcano to the point of activity. As
plate tectonics continuously shift and move they cause effects all along the way. Not only do
these effects include earthquakes which can cause mass destruction on the upper mantle of the
earth’s crust but they are what form the mountains and the earth as we know it. Volcanoes, in all
their majesty, have always fascinated me. However, I’ve never considered all that goes into their
creation. While plate tectonics play a leading role in their activity, I have been very interested as
I have learned the different types of volcanoes. From Cinder cones to Shield volcanoes, there are
so many different types and that has been exciting to learn about.
