...What killed the dinosaurs Introduction: It is one of the greatest puzzles in paleontology. For more than 150 million years, dinosaurs rule the Earth. They were so successful than other animals groups, mammals included, had little change of taking over. Then, 65 million years ago, the dinosaurs disappeared from the world altogether. Did they meet a quick and catastrophic end, or did they fade away gradually? What happened 65 million years ago? In the search for answers to what killed the dinosaurs at the end of the Cretaceous Period in the Mesozoic Era, scientists have looked beyond fossils. Geological evidence also holds clues and has led to many hypotheses, working explanations, of how dinosaurs may have become extinct. The extinction mystery is far from a simple “whodunit.” The same piece of evidence is sometimes subject to multiple interpretations. And, as yet, there is no obvious answer, no piece of evidence that strongly supports only one hypothesis while showing that all others are incorrect. So what do we know about dinosaur extinction, and how do we know it. Evidence: Scientific evidence and observations are the building blocks of hypotheses. At first the same evidence and observations may support different hypotheses. As more evidence becomes available, some hypotheses are proven, others are disproved, and new ones are formed. Hypotheses: A dinosaur extinction hypothesis is a testable statement describing...

...dropped in World War II ripped through the sky as a huge chunk of rock traveling close to fifty-thousand miles per hour was overpowered by the sheer force of aerodynamics and exploded into oblivion (Tagliaferri, 1998). This explosion was an asteroid from space that was on a collision course with the earth; in February of 1994 the asteroid struck. “The asteroid actually broke into several pieces, with one large piece detonating about 34 km above the surface, and a second, much larger piece detonating at an altitude of approximately 21 km” (Tagliaferri, 1998). Scientists were lucky to record this data via satellite to study the force an asteroid can have when impacting firsthand. There is evidence of asteroid impacts covering the surface of the earth and other surrounding planets in space. There are also many theories involving asteroid impacts causing mass extinctions on Earth, the most common being the extinction of the dinosaurs 65 million years ago (deGrasse Tyson, 2005). Most of the impact evidence shows that the earth has been attacked by these asteroids since its formation billions of years ago. Evidence all around us tells us that the Earth will be struck, and another major asteroid impact will occur. The most common and highly argued impact event is the one that may have wiped out the dinosaurs. This event in itself has many theories, but the one common element in most sound dinosaur extinction theories is that a major impact event occurred around the same time the dinosaurs...

The school incorporates other initiatives; however, I believe the aforementioned three to be the most relevant to the school’s aims and pivotal to their continued improvement. I will incorporate other sources of information which will include educational literature, publications, government documents, reports, theories and concepts. I have gathered evidence through independent observation and discussion with the class teacher in order to understand more about the impact of holistic needs on children. During my time at school A, I have utilised observation of children to understand how impacts take effect in different contexts. To conclude, I will identify implications that potentially could impact my future development as a...

...Biology Current Events Assignment Omar Patel May 6th, 2014 Scientists Discover Cosmic Factory for Making Building Blocks of Life September, 15, 3013 Zita Martins, Mark C. Price, Nir Goldman, Mark A. Sephton & Mark J. Burchell http://phys.org/news/2013-09-scientists-cosmic-factory-blocks-life.html In the article it states that when icy comets collide into a planet, amino acids are created. These are the building blocks of life and from the amino acids. This means that amino acids can be created anywhere in the world with these conditions. The article also states that a couple of moons of Saturn have the perfect environment for creating amino acids if a comet hits them. The researchers stated that the comets crash into the ground, which create shockwaves that create amino acids. The scientists figured this out by using a special gun that replicates the crash of a comet. This article is related to science/biology because it helps us understand how life first formed on Earth. I think this discovery will benefit everyone around the world equally because a common question usually asked is how the world was created in a scientific sense. Scientists will be very happy with this information because it would help them keep researching for ideas to satisfy peoples questions related to this topic. Sep. 15, 2013 — Scientists have discovered a 'cosmic factory' for producing the building blocks of life, amino acids, in research published today in the journal Nature Geoscience...

...“What does impact mean to you?” My entrepreneurship professor asked us to define the term in a way that related to our personal goals. A few examples of impact that immediately popped into my head included Embrace Innovation, whose low-cost incubator saved 300,000 babies across 22 countries and Doug Rouch’s Daily Table, which sells fresh, low-cost produce to some of the 49 million Americans struggling with hunger. How did their journeys relate to my aspiring career in dentistry? I recalled shadowing Dr. Starns & Wood who volunteered tirelessly on Tuesday nights, spreading their impact on Charlottesville beyond private practice. Considering social entrepreneurship and dentistry, I defined impact as transforming as many lives possible across multiple...

...was an elevated level of fungi all over the world (now seen in Permo-Triassic rocks), to decompose the vast amount of dead trees. One hypothesis as to how this happened is a possible asteroid impact. This would have sent billions of particles into the atmosphere, blocking the sun and immediately killing plants and most living organisms, triggering the fungal spike. 3. The three lines of evidence for an asteroid impact are the tiny quartz crystals marked with microscopic fractures in rocks from the time of extinction, the enormous 75-mile wide crater in Australia, and also the fungal spike - which proves the extinction of many plants due to the particle blockade of the sun. The meteorite is thought to have made impact below Australia and to be the size of 4.8 km wide. Furthermore, the effects of a meteorite impact would have been again the blockade of the sun by noxious gases, initial lowered temperatures and acid rain, and global warming from the mounting CO2 from fires and decaying organic matter after the clouds had cleared. 4. Focusing on the Earth’s systems, the meteor impact would have changed the course of Earth’s history. The Earth’s lithosphere has been scarred with tiny quartz crystals fracturing rocks that are still visible today. Furthermore, the impact itself left a huge mark through the form a crater 75 miles wide. The atmosphere would have been polluted with noxious gases, which would have also blocked out the sun. As the harmful chemicals lingered around,...

...On February 15, 2013 the small asteroid 2012 DA14 was its closest to Earth. The 50 meter asteroid passed through the gap between Earth and the ring of geosynchronous satellites that orbit earth. Geosynchronous objects orbit around the earth with a period equal to one sidereal day. Asteroid 2012 DA14 passed at about 17,200 miles above the Earth’s surface. The asteroid was discovered in February 2012 by astronomers at the LaSagra observatory in southern Spain. (http://neo.jpl.nasa.gov/news/news177.html)( http://neo.jpl.nasa.gov/news/news174.html) (http://www.merriam-webster.com/dictionary/geosynchronous) An asteroid is a small planet-like body in orbit around the sun. The orbits of some asteroids take them across the paths of the planets. Asteroids are smaller than a planet but larger than a meteoroid, which is a small interplanetary object also in orbit around the Sun. If a portion of a meteoroid or other object survives the entry through the Earth’s atmosphere and reaches the Earth’s surface it is referred to as a meteorite. A meteor, also known as a shooting star, is a streak of light produced by a meteoroid that burns away in the Earth’s atmosphere. When their orbit brings them close to the sun, gigantic balls of ice and rock or comets, form a tail of dust and gas while being heated by the Sun’s rays. Scientists believe that the extinction of dinosaurs, nearly 66 million years ago, was the result of a large meteorite striking what today is Mexico’s Yucatan Peninsula. In...

...more at ease knowing that like that night, it wasn’t about the numbers involved so much as it was about the message being conveyed. Renate’s story is one that cannot be over looked. To hear first hand, and even second hand is so much more impacting then reading about something in books and through articles. As much as Renate impacted me, she was only a small part of the commemoration. Everything came together and flowed very nicely and I found myself more than willing to stay longer then required. My favorite part was the passion shown by everyone involved. Although I didn’t necessarily understand some of the songs and prayers, it was still powerful to say the least. One thing I will always remember, and the thing that made the biggest impact on me was an elderly man who stood next to me towards the end. This man walked in late and although he never spoke to anyone, he sang and participated, eyes closed, with such an intense facial expression of both passion and remorse. As he walked out in silence, still not speaking to anyone, is when I realized just how much this really meant to people. One of my favorite messages from the Candlelight read along given out was the idea that action is what separates belief from opinions and how beliefs are imprinted through actions. This...

...the one that’s missing you. There’s a full moon coming in through the screened window. There’s a breeze sneaking in as well, but the moon is the more important detail. But the most important detail, by far, is the one that’s missing; you. I can picture you in the moonlight; I can pick out a strand of your hair from memory. I can hear a smile from your eyes; if I close mine. I can almost feel your skin the moment before it touched mine. But that takes concentration. I’d much rather stand here, bathed in the moonlight and trying to clear my head. Trying to make sense out of the craters on the moon; trying to guess at the temperature of those far away rocks. Wondering if they’d be warm to my touch. Wondering where you are. Bob Dylan is playing in the background; I wish he’d shut up. He makes not concentrating difficult. I take another drag from the cigarette I’ve been holding but neglecting to mention. Exhaling, I notice that there are two sets of clouds in the sky tonight- one moving slowly and the other breezing by. I steady my gaze on the moon, and the cloud system that is almost static to its side. The other set of clouds hides and reveals the moon at a pace that’s almost like a pulse. I feel fortunate to witness the equivalent of an interstellar circulatory system. And sorrowful that there is such a thing. That nature lacks creativity and imitates its...

...Clyde Steele Guide to the Universe ASTRO 101 IN Naming the Craters The naming of astronomical objects and their features is accomplished as a thoughtful and time-consuming international effort of the International Astronomical Union. They’re an internationally recognized body that, since 1919, has been in charge of naming features on other worlds within and outside the Solar System. Every feature on every planet and moon in our solar system has a particular theme, for instance, craters on the moon are named for dead scientists, engineers, and explorers. In naming ten of the largest craters on Mercury one has to take in account that the regulations for naming a crater on Mercury is that it should be named after a famous writer or artists. According to IAU rules, all new craters must be named after an artist that was famous for more than fifty years, and dead for more than three years, before the date they are named. Of the first five craters chosen to be named, they should be renamed after famous artist from various periods throughout history. The first painter that was chosen was Gustav Kilmt. Gustav Klimt was an Austrian symbolist painter and one of the most prominent members of the Vienna Secession movement. Klimt is noted for his paintings, murals, and sketches during the late 18th century. From the IAU’s rules and regulations on naming craters, Gustav meets all criteria and has been deceased for nearly a century, so seeing as he hasn’t already had a crater named after...
