The dinosaur extinction theory – a large asteroid impact and a giant volcanic eruption at the end of cretaceous – also supports that dinosaurs were cold blooded, when the dust due to the meteorite covered the earth, then the sun light could not penetrate the smoke and dust, thus sunlight did not enter the earth for many years, this lead to the drop in temperature on the land, as dinosaurs were cold blooded they could not raise their body temperature without sunlight and hence were
South vietnam had surrendered to North Vietnam, ending the longest and most unpopular foreign war in U.S. history. The Vietnam War had cost 58,000 American lives and as many as two million Vietnamese civilians and soldiers were killed. 1976 - The Viking 2 spacecraft lands on Mars In September 1976, Viking 2 landed on Mars, following the first successful spacecraft, Viking 1, landing on Mars. Viking 2 was a part of NASA’s two-part mission to investigate Mars and search for signs of life. Neither spacecraft found traces of life, however, they did find all the elements essential to life on Earth, such as carbon, nitrogen, hydrogen and oxygen.
Title Researchers and scientists have constructed extensive research on dinosaur’s extinction. Speculation instead of real evidence seems common in most theories about the dinosaurs’ extinction. However, Jay Gould’s essay “Sex, Drugs, and the Extinction of Dinosaurs” is the complete opposite of speculation over evidence. Rather, Gould uses the mix of persuasive techniques, such as rhetorical questions, logos, along with profound evidence to not only disapprove of other theories but convince readers of his place on the dinosaur’s extinction. As one is able to attest, logos are evident within every passage of this essay.
They also found that it was not just the largest whales that grew over time; the smallest whales found today are larger than the smallest extinct species. Further analysis revealed that the baleen whales had been diversifying in size for 30 million years; this began to take place between 4.5 million and a few hundred thousand years ago. The recent timing rules out the possibility that the emergence of gigantism was caused by the evolution of bulk filter feeding, large predators like giant sharks and falling global ocean temperatures. Slater says that the recent onset of glaciation in the Northern Hemisphere caused the evolution of gigantism in baleen whales. While the scenario for one of the last stages in the evolution of size of baleen whales is convincing, Olivier Lambert, a paleontologist from the Royal Belgian Institute of Natural Science, says that it was likely other factors such as the evolution of large predators and other climatic events which played a role in the development of the animals ' size.
TITLE “Sue” is one of the biggest and most complete T-rex skeleton ever found (text book pg. 140). If this skeleton would’ve been lost to illegal fossil trade dealers, then scientists and paleontologists would have also lost valuable evidence. Fossils are dead organisms that are buried by sediment that hardens, and then preserves the form of the dead organism (text book pg. 141).
Decline and Fall of the Roman Empire The “Fall of Rome,” by coauthors Jake Patterson and Kyle Woodman outlines the factors that led to the decline and fall of the Roman Empire. There is a saying, “All good things must end.” The glory of Rome and the strong Roman Empire eventually fell due to a variety of reasons. All roads led to Rome for over 1,200 years. Rome started as a monarchy, became a republic, and ended up being the biggest empire the world had ever known. The “fall” of Rome cannot be pinpointed to a single day or event in history.
The Permian-Triassic extinction The largest of the Big Five was the end-Permian or Permian-Triassic extinction event roughly 250 million years ago, which eliminated as much as 95 percent of the planet 's species. Before this extinction, marine animals were mostly filter feeders stuck in place on the seafloor, such as crinoids or "sea lilies." Afterward, the seas became far more complex with mobile creatures such as snails, urchins and crabs. The most likely final trigger for the end-Permian was again massive volcanism, this time at the Siberian Traps, which spewed as much as 2.7 million square miles (7 million square kilometres) of lava out, an area nearly as large as Australia. Recent evidence suggests, however, that the end-Permian may have
Some of the people who believe in Nessie not only believe that the in monster but it is actually a dinosaur too. The dinosaur is thought to be the last surviving plesiosaur, which are aquatic dinosaurs believed to have gone extinct 65 million years ago with all other dinosaurs (history.com staff). This iconic monster is also thought to be real because of sonar pictures that have supposedly captured the creature in the depths of Loch Ness. Sonar images of large object in loch ness are common but people are not exactly sure what the images show. This lead to the assumption that the pictures show the Loch Ness Monster (Davies).
It took Alexander 11 years to build his empire, and only 10 years for it to break up after his death (Doc. E). Alexander went through all this trouble killing innocent people, and conquering all this land to build his empire, taking 11 years out of his short life to do this. After his death this empire only stayed as a whole for 10 years. This included 70 cities and 2,000,000 sq.
Seventy three seconds into its flight, the space shuttle Challenger exploded, killing all seven passengers on board, including Christa McAuliffe, who was to be the first civilian in space. This was to be the Challenger’s tenth mission and, sadly, it turned out to be its final one as well. Following an investigation called for by President Reagan, it was determined that the crash was ultimately caused by two rubber O-Rings, designed to separate the rocket boosters, that failed due to cold temperatures on the morning of the launch (“Challenger Disaster”). In his address to the nation on January 28, 1968, President Reagan uses allusion, pathos, and tone to comfort the audience after the catastrophic events. In his speech, Reagan manipulates his
One extinction that occurred was at end Permian, at the end of the Paleozoic era which wiped out about 90% of all species which may be caused by volcanism, meteor, global warming, sea-level changes, glaciation, or ocean chemistry changes. Another extinction that occurred was at end Cretaceous, at the end of the Mesozoic era which made around 60-80% of all species extinct which may have been caused by a meteor impact, volcanic activity, or sea-level change. Another extinction that occurred was at late Pleistocene at the end of the Cenozoic era which made nearly all mammals and birds over 45 pounds extinct, which may be caused by over-hunting by humans.
The giant ground sloth or Megatherium(“giant beast”) is in the mammal classification. the extinct genus of the family Bradypodidae This animal lived from lived from about 35 million to 10,000 years ago. The main reason for the giant ground sloths extinction was the ice age. Some other reasons why this animal went extinct were, human development and hunting. Many experts believe that the giant ground sloth was a herbivore and that it fed on leaves found on low tree branches, bushes and leaves.
Archeologically the dam also represented a loss, as thousand-year-old petroglyph panes and caved dwelling of the Anasazi became submerged. On the other hand, Phoenix thrived, and like the mythological bird is named after, splendidly rose from the desert ashes to become a metropolitan area of 4.3 million
“Here is a true story about the Herbert” “currently he is buried alive at least 20 feet below the surface in a steel box” The museum of Fate plate reads “ Here is a story about the truth of changing one 's fate. A monster is born along with a repeating monster item buried 20 feet below ground and the real story has probably been shut up by the government. A total of 72 people were killed in 70 years. The author was the only known person to survive the first encounter with the beast known to all as Herbert. The monster’s line “Here’s Herbert” was used in the Shining a movie where a father loses his mind and turns into a homicidal maniac where it used and changed into “Here’s Johnny”.
Below the turquoise waters of Mexico’s Yucatán Peninsula lies the site of a long ago mass murder. In a geologic instant, most of the world’s animal and plant species went extinct. Drilling through hundreds of meters of rock, investigators have finally reached the "footprint" left by the accused. That footprint marks Earth’s most notorious space rock impact. Known as Chicxulub (CHEEK-shuh-loob), it’s the dinosaur
