Earth's history are part of the geological time scale. The geological time
scale measures the timing and the relationships of specific occurrences in the
history of the Earth. It is used mostly by geologists and paleontologists. They
define the earth's history by studying the Earth's composition then connect
facts to major geological or paleontological events. <span>

the use of a geological time scale, scientists have found discoveries and put
together the missing pieces of the past. Probably, the most distinguishable event discovered through
the geological time scale is mass extinction of species.</span>

The Iran hostage crisis <u><em>affected negatively the American opinion of President Carter </em></u>to the point that it probably cost him his second term as President of the United States. On November 4th, 1979, a group of Iranian students stormed the U.S Embassy in Teheran taking more than 60 Americans hostages. This action was a direct result of President Carter's decision of allowing the deposed Shah the possibility of getting medical treatment in the United States.
The students set their hostages free on April of 1981, 444 days after the crisis began and just hours before new elected President Reagan delivered his inaugural address.
