Carbon Dioxide Greenhouse Effect
1,080 words
While some people believe the earth's climatic
changes are due to the fact that the universe is
getting older, others believe it is due to the
greenhouse effect. The greenhouse effect is a
naturally occuring phenomenon that is responsible
for trapping heat near the earth's surface and
keeping the planet warm. It is called the
greenhouse effect because the way it works is
similar to the way in which a green house
functions. In a greenhouse sunlight passes through
the transparent roof and walls an...

Multiple Causation Theory Of Leukemia
1,944 words
Leukemia is a malignant disease of the bone marrow
and blood. It is characterized by the uncontrolled
growth of blood cells. The term leukemia has a
Latin derivation. Luke means white and heme is
blood. Therefore the word leukemia literally means
white blood. The common types of leukemia are
divided into four major categories: myelogenous
and lymphocytic, which can then be divided into
acute or chronic. Thus, the four major types of
leukemia are acute or chronic myelogenous leukemia
and acute or...

Ozone Layer Ultraviolet Rays
1,294 words
Atmospheric ozone layer depletion is a serious
problem currently facing the world. The ozone
layer protects humans, animals, and plants from
harmful ultraviolet rays. Money and time are being
spent on ozone repair, but the problem still
exists. The ozone layer is a region of the
stratosphere containing ozone, or O 3 gas. The
ozone layer is essential to both plant and animal
life on earth because it protects the surface from
dangerous ultraviolet light. However, industrial
and domestic chemicals ...

Stimulated Emission Positively Charged
948 words
Lasers HISTORY OF LASER PRODUCTION The roots of
laser mechanism are very modern. In 1900 German
physicist Max Planck presented an explanation of
why the colors of a glowing hot body may change
with temperature. He also proposed discrete
quantum theory saying that radiations come in
discrete quantities called quanta. Therefore
radiations are not only a series of waves but a
stream of particles called photons. By 1917,
Einstein has outlined the principles underlying
the production of laser radiati...

Rise In Sea Level Atmospheric Co 2
1,132 words
Global Warming Debate The global warming is caused
by emissions of over 20 gases into the atmosphere.
The major contributors are carbon dioxide (CO 2),
ozone, methane, nitrous oxide and
chlorofluorocarbons (CFCs). Although these gases
are produced by many industrial processes, the
major source is the burning of fossil fuels in
boilers, furnaces and automobile engines. When
released into the air in large quantities, these
gases cause the earths atmosphere to warm by
trapping the suns heat. Infrar...

environmental disasters in the world. The plant
was made up of four graphite reactors, which were
the most modern Soviet reactors of the RBMK-type.
Two more of these reactors were still under
construction at the station. Chernobyl was an
obscure town in north central Ukraine (former
Soviet Union) on the Pripyiat River near the

World War Ii Drop The Atomic Bomb

When the atomic bomb went off over Hiroshima on
Aug. 6 th, 1945, 70, 000 lives were ended in a
flash. To the American people who were weary from
the long and brutal war, such a drastic measure
seemed a necessary, even righteous way to end the
madness that was World War II. However, the
madness had just begun. That August morning was
the day that heralded the dawn of the nuclear age,
and with it came more than just the loss of lives.

Big Bang Theory Force Of Gravity
1,630 words
Not so much a theory of the universe as a simple
picture of the planet we call home, the flat-earth
model proposed that Earth? s surface was level.
Although everyday experience makes this seem a
reasonable assumption, direct observation of
nature shows the real world isn? t that simple.
For instance, when a sailing ship heads into port,
the first part that becomes visible is the crow?
s-nest, followed by the sails, and then the bow of
the ship. If the Earth were flat, the entire ship
would come ...

Solid State Lasers Beam Of Light
1,373 words
A laser (LAY zum) is a device that produces a very
narrow beam of light. This is called coherent
light. It is formed from producing light at equal
wavelengths in phase. The result is a beam of
light that does not stray from it? s path.
Conventional light bulbs produce incoherent light.
This form of light diffuses immediately upon
radiation from its source. The size of a laser
beam varies greatly. Some lasers produce beams
that are small enough to fit 200 beams in an area
the size of a pinhead. T...

Stratospheric Ozone Ozone Layer
2,496 words
The Atmospheric Ozone Layer The stratospheric
ozone layer exists at altitudes between about 10
and 40 km depending on latitude, just above the
tropopause. Its existence is crucial for life on
earth as we know it, because the ozone layer
controls the absorption of a portion of the deadly
ultraviolet (UV) rays from the sun. UV-A rays,
including wavelengths between 320 and 400 nm, are
not affected by ozone. UV-C rays between 200 and
280 nm, are absorbed by the other atmospheric
constituents besides...

matter, usually metals, when it is irradiated by
light or other electromagnetic radiation. The term
photoelectric effect designates several types of
interactions. In the external photoelectric
effect, electrons are liberated from the surface
of a metallic conductor by absorbing energy from
light shining on the metals surface. This is the
form that we g...
