The Forever Moving Land
.... from the magma (approximately
2700(C) causes convection in the mantle (Figure 1). Convection is caused by
non-uniform temperature in a fluid and density differences. This continuous
convection is the cause of plate movement. Each complete cycle, called a
convection cell, drives the plate in the direction of the cell. How does a
'solid' mantle move? The mantle may be solid but, as with most solids, it will
deform if long term stress is applied; "...like Silly Putty which seeps into
the rug when left unattended, mantle material flows when subjected to small
long-term stresses."1
Presently, there are more than fourteen plate .....

Mercury
.... percent of Mercury’s
surface, were formed by huge rocks that smashed into the planet’s surface. The
largest crater is called the Caloris Basin and it is 1400 km in diameter and is
flooded with molten lava. Mercury also has many cliffs that are usually over
300 miles long and two miles high. The rest of the planet’s surface is smooth
and may have been formed by lava flowing out of cracks in the surface.
Temperatures on Mercury vary greatly because of it’s closeness to the
sun. The surface temperature on the sunlit side is about 430 degrees Celsius,
while the dark side may reach temperatures of -170 degrees Celsius..

Environmental Crisis
.... in the east. These nations are
among the world's poorest.
The area is one of social and biophysical crisis because of the way the
population are forced to live; they are destroying the productivity of the land.
The alarming rate of population growth and ever increasing pressure on the land
have initiated an expansion of desert-like conditions into the Sahel - a process
called desertification.
Traditionally, the people of the drier, northern Sahel followed a nomadic
lifestyle, constantly moving their herds of cattle, sheep and goats over large
areas in the search for suitable grazing land. These movements prevented
overgrazi .....

Cloning
.... number of copies of an
individual, is each one special? How special can clones feel, knowing they were
replicated like smile buttons. "We aren't just our genes, we're a whole
collection of our experiences," says Albert Jonsen. But the idea, he adds,
raises a host of issues, "from the fantastic to the profound."
When anesthesia was discovered in the 19th century, there was a speculation that
it would rob humans of the transforming experience of suffering. When three
decades ago, James Watson and Francis Crick unraveled the genetic code, popular
discussion turned not to the new hope for vanquishing disease but to the specter

My Theory Of The Universe
.... the middle

are always winking. They are sometimes on the first floor and sometimes on the
second floor. (Mars, Jupiter, and Saturn) There is also one guy dressed in a
white polyester leisure suit, gold chains, and rings dancing to "Stayin' Alive."
(comet) It seems as though everyone in the universe hears their own music. He
is only in the room for a little bit; he makes his way across the room then
leaves, he must get tired really quick! Sometimes when he is dancing or even
when you can not see him dancing, (must have forgot his gold chains) somehow .....

Genetically Altered Foods
.... That which was debated dealt with the Advisory Committee
on Novel Foods and Processes (ACNFP) stating that "A gene resistant to the
antibiotic ampicillin used in an early stage of the developmental process, could
theoretically be passed to man via bacteria lodged in the gut of animals which
eat the maize unprocessed (559)". In response to this attack, the company said
that there would need to be a great amount of events that would have to take
place. The transferring of DNA to the bacteria is just one of which was
addressed. Therefore, the issue isn't settled. One then can only assume that
until a hault is put on altering, the ind .....

Salt And Its Uses
.... diet, or later when salt was
introduced, Of the hypertensive subjects, half of those on the low salt diet did
experience a drop in blood pressure, which returned to its previous leel when
salt was introduced.
Of course, these are other researcherswhgich tend to support the
findings. A small Indiana study showed that when normal individuals took large
amount of salt, the bolld pressure did not consistenly rise into the
hypertensive range. Also, study in Israel showed that a low-calorie diet could
reduce blood pressure without changing salt consumption. After viewing research
statistics, we should know that salt is not .....

Bovine Spongiform Encephalopathy
.... overall conclusion (Stadthalle, 1993). These
lesions are consistent with the diseases of the more common scrapie family.
Without further investigation, the conclusion was made that BSE was a new member
of the scrapie family (Westgarth, 1994).
Transmission of BSE is rather common throughout the cattle industry.
After the incubation period of one to two years, experimental transmission was
found possible by the injection of brain homogenates from clinical cases
(Swanson, 1990). This only confirmed that BSE is caused by a scrapie-like
infectious agent.
How does the transmission become so readily available among the entire

Zinc is required to keep your blood sugar level controlled. You also
need to so you can taste and hear properly. It also helps to heal cuts. You
should have about 15 mg per day of zinc.
Boron is a mineral that helps keep strong bones. It affects calcium and
magnesium. This also helps out so you have proper membrane functions.

Abstract From: Cloning : Where Do We Draw The Line?
.... in
livestock for the past ten years, and some scientists believe that it seems only
logical that it would be the next step in in-vitro fertilization. The procedure
was remarkably simple. Hall and Stillman "selected embryos that were abnormal
because they came from eggs that had been fertilized by more than one sperm"
(Elmer-Dewitt 38), because the embryos were defective, it would have been
impossible for the scientist to actually clone another person. They did however,
split the embryos into separate cells, as a result creating separate and
identical clones. They began experimenting on seventeen of the defective
embryos and " .....

Neptune
.... Helium, and 2% methane. The planet's atmosphere, particularly
the outer layers, contains substantial amounts of methane gas. Absorption of
red light by the atmospheric methane is responsible for Neptune's deep blue
color. Neptune is a dynamic planet with several large, dark spots reminiscent of
Jupiter's hurricane-like storms. The largest spot, known as the Great Dark Spot,
is about the size of the earth and is similar to the Great Red Spot on Jupiter.
Neptune receives less than half as much sunlight as Uranus, but heat escaping
from its interior makes Neptune slightly warmer than Uranus. The heat liberated
may also be respon .....

Acid Rain

plants. the acid also drain the soil of essential nutrients such as aluminum and
releases them into bodies of water such as streams, lakes, and ponds. These
bodies of water develop highly concentrated levels of these nutrients which can
really harm the aquatic life forms in that area Those areas without any alkaline
metal deposits in the soil to neutralize some of the acid are hurt the most by
this destructive force, destroying crops, trees and even killing an entire pond
or lake. Acid rain is also a strong destructive force against man made
structures, reacting .....
