Hurricane Floyd
<view this essay>.... extremely large area’s of low pressure that are over the ocean in either the North Atlantic ocean, or the eastern North Pacific Ocean. If a hurricane is in the western Pacific Ocean than it is called a typhoon. One in the Indian Ocean is called a cyclone. The danger region of a hurricane is normally in the Gulf of Mexico or the Atlantic Ocean. The hurricane season is the six month time period from June-November. The peak month of hurricanes is September.
Hurricanes form over the ocean. Easterly waves, what hurricanes develop from, are long, narrow regions of low pressure which occur in ocean winds called trade winds. At first, these easterly waves can .....

The Beginning Of The Universe
<view this essay>.... state from which the universe rapidly expanded.1 The Big Bang was
the start of time and space. The matter and radiation of that early stage
rapidly expanded and cooled. Several million years later, it condensed
into galaxies. The universe has continued to expand, and the galaxies have
continued moving away from each other ever since. Today the universe is
still expanding, as astronomers have observed.
The Steady State model says that the universe does not evolve or
change in time. There was no beginning in the past, nor will there be
change in the future. This model assumes the perfect cosmological
principle. This principle says that the universe i .....

Changes In The Atmosphere Causing Multicellularity
<view this essay>.... life on land possible and evolution occurred as
prokaryotes gave rise to land living eukaryotes.
The microfossil record indicates that the first eukaryotes evolved at least
1.5 billion years ago. Eukaryotes are distinguished from prokaryotes by their
larger size, the separation of nucleus from cytoplasm by a nuclear envelope, the
association of DNA with histone proteins and its organization into a number off
distinct chromosomes, and complex organelles, among which are chloroplasts and
mitochondria. Scientists believe that eukaryotic organisms such as the protists
evolved from the prokaryotes. There are two main theories which describe how
this transi .....

Turkey Vultures

service to find wasteful and dangerous gas leaks. And the vulture’s unique
knack for conserving energy has intrigued scientists for years.
Although the turkey vulture has a large, turkeylike body and sporty red
head, it is not even distantly related to the turkey. Instead, turkey vultures-
along with their cousins in the United States, the black vulture of the South
and East, and the nearly extinct California condor-belong to a group of raptors
called New World vultures. Chromosome analysis shows that the New World
vultures are actually more closely related to storks than to the vultures of
Europe, Asia, and Africa.
Turkey vultures are rema .....

Endangered Species
<view this essay>.... by humans activity. Clearing land for farms and towns, lumbering, mining, building dams, and draining wetlands all alter the environments so extensively that ecosystems may be completely destroyed. With a burgeoning human population requiring food, shelter, and clothing and constantly demanding more energy-using devices, the temperation to exploit land for human use without regard for consequences is great. Frequently, several forms of environmental change are responsible for the disappearance of species. For example, as tropical forests are cut down, primates have progressively smaller feeding and living spaces. They also become more accessible to hun .....

Inventions Benefited Society
<view this essay>.... employees' health information can also be
kept in computers. In the early days, we had used papers and pens to record data that we gathered. As a
breakthrough technology today, computers have replaced pens and papers. Many businesses are now relying on
computers because their statistics and calculations are more accurate than manual calculations. These machines
are enabling us to perform many different tasks in less time and making our lives easier.
Computers in telecommunications have allowed us to do many things from the comfort of our homes
that could never be done before; such as talking with distant friends and relatives, buying merchan .....

Homo Aquaticus?
<view this essay>.... (evolution relationships), more alike than chimps and gorillas.
But the brains of chimps and humans differ in size and anatomy more than
gorillas and chimps. The brains of chimps and gorillas probably didn't go
through many evolutionary innovations, because they generally resemble other ape
and monkey brains. This implies that the human brain changed a lot after the
human/chimp evolution. With the exception of the olferactory bulb (scent), all
brain structures are larger in humans than in apes. The neocortex (part of the
cerebral cortex), for instance is over three times larger than in chimps, even
though chimps and humans are prett .....

Are UFOs Real?
<view this essay>.... come about? There are certain reasons and possible explanations as to why UFO's became so popular at one particular time. After the great appearance of UFO's did become so popular it seems as if the media did as well. Whatever the media says or mentions one breath of usually spreads so quick and gets so out of hand it is almost as unbelievable as a UFO being real. Another odd fact about UFO's is that if they are suppose to be out there somewhere why did the government stop research on them? Maybe they got tired of spending money on something that was getting them nowhere. The overall and main question that has been asked for many, many years is, "Are .....
