Geothermal Energy

Physics 009
Professor Arns
The human population is currently using up its fossil fuel supplies at
staggering rates. Before long we will be forced to turn somewhere else for
energy. There are many possibilities such as hydroelectric energy, nuclear
energy, wind energy, solar energy and geothermal energy to name a few. Each one
of these choices has its pros and cons. Hydroelectric power tends to upset the
ecosystems in rivers and lakes. It affects the fish and wild life population.
Nuclear energy is a very controversial subject. Although it produces high
quantities of power with relative efficiency, it is very hard to dispose of the
waste. While wind and solar power have no waste ...

swirled around a
dense core in the middle. As time went on the accumulation elements with
similar physical properties into hot bodies caused a slow formation of a
crystalline barrier around the denser core. Hot bodies consisting of iron were
attracted to the core with greater force because they were more dense. These
hot bodies sunk into and became part of the constantly growing core. Less dense
elements were pushed towards the surface and began to form the crust. The early
crust or crystalline barrier consisted of ultra basic, basic, calc-alkaline, and
granite. The early crust was very thin because the core was extremely hot. It
is estimated that the mantel e 200 to 300 degrees Celsius warmer than it is
today. As the core cooled through volcanism the crust became thicker and cooler.
The earth is made up of four basic layers, the inner solid core, the outer
liquid core, the mantel and the lithosphere and crust. The density of the
layers gets greater the closer to the ...

in partial plate
destruction. This causes mass amounts of heat to be produced due to frictional
forces and the rise of magma from the mantle through propagating lithosphere
fractures and thermal plumes sometimes resulting in volcanism. During plate
movement, continental plates are constantly being consumed and produced changing
plate boundaries. When collisions between plates occur, the crust is pushed up
sometimes forming ranges of mountains. This is the way that most Midoceanic
ranges were formed. Continental plates sometimes move at rates of several
centimeters per year. Currently the Atlantic ocean is growing and the Pacific
ocean is shrinking due to continental plate ...
