Recommended: Dinosaurs extinction

In many theories about the dinosaurs disappearing many say meteors are the reason, is that true? The many theories about dinosaurs disappearing is a huge meteor or asteroid,climate change, volcanic eruptions, lava,and fractured crystals. At the same time there are over 40 theories of why the dinosaurs disappeared, but I only listed the most important ones that were mentioned the most. The biggest theory of all of them is the meteor, people think the meteor collided with earth consequently it struck it so hard that enough dust consequently debris came up and blocked the sun and it pushed the sun out long enough to that the earth's climate changed, most of the plants died out and that caused the dinosaurs who were herbivores to die out then

    However, asteroids are much more deadly. If over-sized meteor can wreck buildings and injure people, then a normal sized asteroid can easily wipe out species if it lands in the right place. As mentioned before, asteroids are much bigger than meteor and much more rare. According to the “Mail Online” 12,000 years ago some type of asteroid slammed into the Northern Canada and some scientist believe that wiped off the mammoths and caused the “Younger Dryas”. Another famous event of asteroids striking, that many scientist believe, was around 65 million years ago asteroids rained and killed of all the dinosaurs 75% of all the life on earth.

    The possibility if a meteor strike as the cause of extinctions is discarded, something that most specialists agree on. There is no evidence of any meteor crater big enough or recent enough to be accountable for it; there are no “elements that are common extraterrestrially but less so on Earth, such as iridium, and no sign of a tsunami or other phenomena following the impact.” The extinctions where also very selective and occurred over a very long period of time. If a “one shot” catastrophe had been the cause it would have affected all species at the same time and in similar

  • The Extinction Event and Life in the Post-Apocalyptic Greenhouse

    840 Words  | 2 Pages

    The biggest mass extinction of the past 600 million years (My), the end-Permian event (251 My ago), witnessed the loss of as much as 95% of all species on Earth. Key questions for biologists concern what combination of environmental changes could possibly have had such a devastating effect, the scale and pattern of species loss, and the nature of the recovery. New studies on dating the event, contemporary volcanic activity, and the anatomy of the environmental crisis have changed our perspectives dramatically in the past five years. Evidence on causation is equivocal, with support for either an asteroid impact or mass volcanism, but the latter seems most probable.

  • The Permian Triassic Mass Extinction

    581 Words  | 2 Pages

    The Permian Triassic extinction was an event of cataclysmic disaster and almost the extinction of all species on planet earth. The Permian Triassic extinction is said to have occurred millions of years ago, geologist have estimated that its occurrences happened about 248 million to 286 million years ago. This rare occurrence of events proceeded the Triassic geologic periods and the Paleozoic and Mesozoic eras. This mass disaster was the largest dissipation of living life on planet earth; it is believed to be even superior to other crises such as the Ordovician and Devonian events and the conclusion of the cretaceous era that came upon the dinosaurs.

    The Permian-Triassic extinction event is undoubtedly the largest extinction event the Earth has ever seen. While evidence shows that it occurred over a great amount of time, it was effective in causing the extinction of an incredibly large portion of life on Earth. To such an extent that it took millions of years before any large amounts of biodiversity occurred again. This is why it is also referred to as the ‘Great Dying’.

  • What Really Happened to the Dinosaurs?

    1031 Words  | 3 Pages

    There has been a debate about what happened to the dinosaurs since they were discovered. There are many thoughts of what happened to the dinosaurs, the two main theories behind the extinction are scientific and religious. Proof for both theories do exist and debates between scientists are still going on to which one really happened. It is a mystery as much for Evolutionists as it is for Creationists about the extinction of the dinosaurs. The fossil record of dinosaurs was poorly know for a long period of time. During this time period was when the dinosaurs were thought to have gone extinct. The scientific reason for their extinction was that there was a giant asteroid that caused chain reaction and wiped out the dinosaurs. Some scientists say the dinosaur’s extinction came quickly. Evolutionists say the dinosaurs went extinct 65 million years ago. Creationists say that the dinosaurs weren’t able to survive the Earth after the flood. Both of the theories have supporting evidence and that is why there is an ongoing debate over what really happened to the dinosaurs.

    Throughout Earth’s history there have been many changes. These changes have consisted of temperature fluctuations, atmospheric differentiations, extinctions of various plant and animal life, etc. Over time everything seems to have evolved in some way form or fashion. However, the Permian Era extinction was different from all the rest. This extinction affected every form of life, but especially the marine life. Researchers have stated that 93-97% of all Earths species went extinct during this period of time. This essay will explain how a once blossoming progressive era turned into Earths most catastrophic event.

  • Global Warming: A Look at Both Sides of the Issue

    2372 Words  | 5 Pages

    Throughout history climates have drastically changed. There have been shifts from warm climates to the Ice Ages (Cunningham & Cunningham, 2009, p.204). Evidence suggests there have been at least a dozen abrupt climate changes throughout the history of the earth. There are a few suspected reasons for these past climate changes. One reason may be that asteroids hitting the earth and volcanic eruptions caused some of them. A further assumption is that 22-year solar magnetic cycles and 11-year sunspot cycles played a part in the changes. A further possibility is that a regular shifting in the angle of the moon orbiting earth causing changing tides and atmospheric circulation affects the global climate (Cunningham & Cunningham, 2009, p.205). Scientific studies suggest that all these played a role in past global warming and cooling periods. Today, however, there is a lot of conflict on whether humans are causing a global warming that could be disastrous to humans and all species of plants and animals on this earth. This paper will first explain the greenhouse effect, then take a look at both sides argument, and, finally, analyze the effect of global warming on world-wide sustainability

    Several mass extinctions have occurred during the Earth’s history. The Cretaceous – Tertiary Boundary (K-T) Extinction caused the loss of at least three-quarters of all species known at that time including the dinosaurs. The cause of this mass extinction is a controversial subject among scientists but the fossil evidence of it’s occurrence is abundant.

    Some scientists believe that mammals out competed dinosaurs for food and other resources. The last theory that dinosaurs died due to a large amount of volcanism comes up in scientists list of theories as well. Many different theories of why dinosaurs went extinct include extinction by asteroid, mammals outcompeting dinosaurs, climate change and volcanism. The most popular theory of dinosaur extinction, the asteroid theory, says that dinosaurs died out because of a single, giant asteroid. They say that the asteroid that struck the earth near the Gulf of Mexico went 43,000 mph and spanned six miles wide (Erdman).

    Biodiversity loss can lead to extinction, and hurt human life. It is our responsibility to take care of the environment. We bring in machines that harm the environment and destroy animal life. We need to limit ourselves on how much land and resources we consume. There are major issues that are causing species to become extinct and hurt our way of life and other animals do to the change in food chain.

  • Loss of Biodiversity

    998 Words  | 2 Pages

    Nowadays it is common to read articles in newspapers and magazines regarding biodiversity issues. Human beings have been knowingly and unknowingly destroying biodiversity since their existence. Biodiversity is the measure of the variety of species of animals living in an area. Forests are usually areas with high biodiversity while deserts are the opposite. Human beings have always destroyed biodiversity either by deforestation, or by some other means. Biodiversity depletion is a natural phenomenon. But the present levels of biodiversity depletion are many times higher than the natural rate. Recently the levels of loss in biodiversity have started causing global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth.
