Supercontinent

The Paleozoic Era, which lasted from about 542 million years ago to 251 million years ago, was a time when different changes existed on Earth. The era began with the breakup of one supercontinent (Pangea) ,and the formation of another. In addition, plants became common, and the first vertebrate animals populated land. The Paleozoic began with the Cambrian Period about 53 million years best known for leading in an explosion of life on Earth. This Cambrian explosion encompassed the evolution of…

An isotope is an atom containing different numbers of neutrons, differing in atomic mass. Basically an atom with a different atomic mass. What’s special about radioactive isotopes is that a radioactive isotope has a nucleus that decays spontaneously giving off particles and energy. 6. Radioactive tracers are used in science to label certain chemical substances, so metabolic processes can be followed and substances can be located in an organism. Radioactive tracers are important diagnostic…

The Mongolian people once ruled the second largest empire in the history of humanity. The Mongol empire was famous for pioneering military tactics such as horse mounted archers, conquering much of the Eurasian supercontinent and ruling an empire whose size would not be matched until the British took to colonialism centuries later. But as with so many other great empires, people often forget the massive economy necessary to sustain such as vast empire. Millions of people living across an entire…

In the beginning of the Bible God created wonderful things, he created many people and then a blessing came along, 29 He named him Noah[c] and said, “He will comfort us in the labor and painful toil of our hands caused by the ground the LORD has cursed.” This occurred In (Genesis 5:29) to me this is a foreshadow of what will happen in the near future. In chapter 6 of Genesis God only saw hate in the people he created and this made him have a heavy heart and he decided “7 So the LORD said, “I…

Sustainability has become an issue throughout the whole globe. Sustainability is a complicated term which generally means an “approach to development that meets the needs of the present without negatively affecting the ability of the future generations to meet their needs.”(Clarke, Earle, and Wallace, 2006) According to Land Learn organization sustainability means “an ability or capacity of something to be maintained or to sustain itself.” (http://www.landlearnnsw.org.) In my opinion, it is…

many aspects of new world civilizations arose across Europe and Asia, most profoundly in the Middle East. Moreover, in this paper, I will introduce you to many of Crosby’s illuminating statements made in his book. Crosby first delves into the supercontinent of Pangea and how the breaking up of this huge land mass led to the spread out of Homo sapiens across the globe. Crosby states that “The break-up of Pangea and the decentralization of the of…

The Cambrian explosion is referred to as “Biological Big Bang” (Science News) or “Evolution’s Big Bang” (Science) (Levinton, J. S.1992), because of the unexpectedness presence of animal life in the Cambrian. Figures have it that it started back 542 million years ago and terminated approximately 40 million years later. This era is marked by the emerging of profuse skeletonized metazoans, an abrupt intensification in biodiversity and the appearance of most modern lives (Von Bloh 18). Animals that…

and even continents after the Pangaea. Plate tectonics explains that continents could have broken up, but there are 2 major theories on how. Catastrophist’s believe that a series of catastrophes caused things like plates, and the splitting of a supercontinent-Pangaea to happen in thousands of years. Uniformitarian’s believe after millions or billions of years, these things happened and often times used to try and explain evolution, although…
