Earth

from the time people first started having a control over ecosystems; influencing environmental ecologies all over the world (Robbins, Hintz, & Moore, 2014 p.4). With this definition, it is implied that humans have had a large enough impact on the earth in order to significantly change it to the point it cannot go back to the way it was. Therefore, the question then becomes, have we as humans really changed the world so much to cause permanent damage and, if so, should…

the Latin word terra which means earth, land, or territory according to dictionary.com. From this, terrestrial planets literally means Earth-like rocky planets. This contrasts from gas giants, since gas giants are mostly composed of gases, as assumed from its name. Terrestrial planets are also known for their solid surfaces made out of rocks or metals with a massive metal core. Only four known planets fit this description in our solar system: Mercury, Venus, Earth, and Mars. Interestingly…

Eratosthenes was a Greek mathematician, poet, and astronomer, but he is most famously known for being the first person to make a measurement for the size of the Earth. Over 2000 years ago, at the city of Syene, the sun’s rays fell upon a temple column casting a shadow, (1). The scientist noticed that as the sun reached midday, the shadow would not be casted since the sun was directly over the column. However, 800 kilometers to the north in the city of Alexandria, at the same moment at noon,…

pull is of these planets. It’s interesting that in millions of years the debris of Phobos will be orbiting around Mars for a short period of time and the rest will form craters on the surface. Other interesting information that I learned was that Earth once had a ring when the moon was forming billions of years ago and may be the only terrestrial planet that has ever had a ring. The information given about Mars in the article was interesting and I wonder how many other discoveries scientists…

Helium falls under is the Noble Gases. The element has an atomic number of 2, an atomic mass of 4 and is classified as a non-metal. It is the second most abundant element in the universe. Helium was discovered on the sun before it was found on the earth. In 1895, Pierre-Jules-César Janssen, a French astronomer and Norman Lockyer, an English astronomer both who discovered the element helium; found out about it while studying the solar eclipse where they found a yellow line surrounding the sun's…

surging growth of carbon dioxide can have on our air, atmosphere, oceans, and even Earth’s biodiversity. The rising acidity in the oceans show that the excess of carbon dioxide is starting to affect our Earth. With the sizes of coral reefs diminishing and marine life suffering, it is evident that the Earth is being affected by the rise of carbon dioxide gases. Another point that…

How can some live in a society with access to a wealth of information accessible in less than a second still believe the earth is flat? This question is easily answerable in one word: misinformation. Unsurprisingly, the answer to this question invariably raises other questions. However, rather than focusing on questions surrounding the qualifications of misinformation, perhaps a question that deals directly with misinformation’s nature should take center stage: “How is misinformation spread?”…

voice in our society, and we have to make urgent changes so the Earth can remain a livable place for our grandchildren. Friedman’s essay is very effective because he uses rational, emotional, and ethical evidence to support his argument. Friedman provides significant rational evidence to prove how climate change is a vast issue in society. The main logical information Friedman writes is about the effect that greenhouse gases have on Earth. When greenhouse gases are emitted into the atmosphere…

such a big deal? It’s simply a natural phase our Earth is going through. Its claimed that Carbon Dioxide emissions are what has got us to this point but less than 0.0022 % of those emissions are actually man made, meaning that majority of them are naturally emitted from the mantle of the Earth. Professor of Geology and Earth Sciences at the University of Adelaide, stated that…

that Xram's society noticed on earth, was that there was a slight trace of radioactivity in the earth's atmosphere. They did that by applying their scientific skills, by analyzing the atmosphere and applying scientific principles, which shows that Xram's society is advanced in science. In addition, there was another thing Xram's society noticed and applied their science skills with and that was to determine whether or not Uranium was the cause in obliterating the earth and destroying life on the…
