...The Bible says that this beautiful Earth on which we live was created by God for Adam and Eve to live in and those we are the descendants of Adam and Eve. For centuries many philosophers in the East and in the West including the Greek philosopher Aristotle believed that earth is the centre of this universe. It was left to Galileo, a prominent mathematician of Padua University to announce his discovery on January 17, 1610 that the Earth is a planet just like other planets revolving round the Sun, which is a star. It was also established that the sun due to its gravitational pull attracts all these planets which revolve round it. Apart from the Earth there are some other planets which go round the sun. These planets, however, vary in size and also in their distance from the sun. They have their own orbits, and the period of rotation also varies in each case. Some of these planets have satellites called moons, varying in number. Some do not have any satellites. Normally, if they do not have a counter pull, they should have been dragged into the sun by the gravitational pull. These gravitation pulls of the sun and the counter pulls of the planets are called centrifugal forces. The planets revolve round the sun in their own specific orbits. These planets could be arranged in an order based on their distance from the sun. The nearest to the sun is Mercury and the next is Venus. Third comes the Earth. Later in the same order come Mars, Jupiter, Saturn, Uranus, Neptune and......

Earth Science

...What is the differnce between earth science and biology? earth science is rocks minerals and the study of the earthen sphere and all that make it. biology is about organic compounds and anything living (bio) that has home on it. Why is it important to study Earth Science? Because we find out about the earth and its environment from the books. How the environment affected the people on earth and what precautions should we adopt so we can get along with it. It also is important because you get to know more about your earth. The simple answer is, because it's awesome. Otherwise, Earth Science is very important in understanding how our world works. It has many different applications, from oil and mining, to waterways and seas, to understanding Earth History, and to engineering and building, as well as many others. Because you want to know about the Earth? Or because you think that the qualification will help you to get the type of job that you want. SO we can make good predictions an be prepared what can happen in the future. One example of a bad prediction is 2012. 1st. the myians never predicted that. 2nd. My dad talked to a scientist about it and he said everyone that's saying different ways that other people said the world is going to end is fake. so we will know that earth science is literacy of critical importance to our nature.

The Future

...grave to us, yet if we were to possibly use wisdom, we may miss the pitfall all together. The wisdom of learning from the past, of individually taking control, making a change and not relying on the powers that be, is one strategy. “Makes me wonder if all the wisdom was given to King Solomon and none left for us”, but even he faltered. So then it begs to say is there any purpose, reason or hope. Do we just literally exist and go round on a cog wheel of time. Without straying too far from the point, there is allot of room left for speculation as to whether some of these conspiracy ideas are true. Were we just put here and are aimlessly wondering this planet. While I was doing this piece it brought up allot of question about the past, future, who we are, why we are here? How our world/universe came to be? Is this all about balance and not right or wrong? TECHNOLOGY seems to be our vice, we are moving very rapidly towards an I.ROBOT society where we become so reliant on technology, we become the vegetable scientist of the past predicted. We no longer seem to live in natural time and with nature. The sculpture is a representation of the state we are partially in and on our way to. The robot is to encompass technology and the era of humanoid robotics we are embarking on. Although IRobot was a movie, it does seem as if it could be a likely possibility of what is to come. With the woman half the size of the robot she is being torn apart as a representation of man’s state of......

After Earth

...Scott Bushard Nolan Belk ENG 111-001 Movie Review 03 October 2013 After Earth “Then it dawned on me, Fear is not real. The only place fear can exist is in our thoughts of the future, it is a product of our imagination, causing us to fear things that do not at present and may not ever exist, that is near insanity. Now do not misunderstand me, Danger is very real, but fear is a choice. We are all telling ourselves a story, and that day, mine changed.” That is a quote from Cypher (Will Smith) talking to his son Kitai (Jaden Smith) after their crash landing on the planet where the ship broke in two, leaving the only working beacon in the tail of the ship some 100 kilometers away from them, on earth 1000 years after they have left it. "After Earth" is a lovely surprise. This film from producer-costar Will Smith and director M. Night Shyamalan, about a father and son marooned on a hostile future earth, is a moral tale disguised as a sci-fi blockbuster. It's no classic, but it's a special movie: spectacular and wise. Says Matt Zoller Sietz from If you’re looking for an action adventure, or a pure Sci-Fi you might be disappointed as the storyline isn’t after that. If you notice little backdrop details about the scenes of the movie and love an interesting storyline, that’s where this movie comes through very strong. It isn’t just about a father and son being shipwrecked on a planet, or even about them bonding together even though it does cover that......

Date: Introduction Near-Earth Objects (NEOs) can be defined as heavenly bodies or solar system objects that have been pulled gently by the gravitational force of the Earth bringing them close to into orbits and the Earth’s neighborhood. These NEOs include Near-Earth comets, Near- Earth asteroids, meteoroids and a few solar-orbiting spacecraft huge enough to be trailed in space before hitting the Earth. The collision of the NEOs in the past has had a significant part in shaping the biological and geological history of the Earth. Near-Earth asteroids (NEA) have orbits that rest between 0.983 to 1.3 astronomical units from the sun (Shapiro, 1999). Due to this the Earth’s orbit cross with some NEA orbits posing a collision danger. By 2012 August there were 848 Near-Earth asteroids that were larger than 1km and 154 of those had were potential hazardous asteroids (PHAs).Comets are mostly composed of ice water with engrafted dust particles. They are formed on the outer system of the planet. The asteroids are mainly rocky and are formed in the warmer inner solar system between the orbits of Jupiter and Mars (Bally, Reipurth 2005). Scientific interest in asteroids and comets is due to their status because they have unchanged debris from the solar system formation dated back to up to 4.6 billion......

Earth Essay

...Humans often wonder what their obligations are and what they owe their fellow man. There are many answers to this inquiry, as there are many things we owe to each other as human beings. Every human being has an obligation to care for our planet Earth. We owe it to our predecessors as well as our future generations to protect and preserve the planet. We owe protection to the Earth for providing us with abundant resources and allowing us to inhabit it. In Recent years, humans’ negative effects on the Earth have become more evident. Pollution is slowly rotting away the protective ozone layer, causing ice caps to melt and the water levels to increase. The animal population suffers because of over-hunting, poaching and the destruction of habitats. Humans are taking advantage of the planet Earth, and our careless ways are slowly destroying this beautiful planet on which we live. The animals with which we share this planet are facing the brunt of our mistreatment of the Earth. The Endangered Species list is growing at an alarming pace, and no region is safe. “One in four mammals is threatened with extinction” (Rogers, EarthFirst) In Africa, elephants are being hunted for ivory and lions are being hit by cars on roads going through their habitats. The alligator population of the Florida Everglades is dwindling due to habitat destruction and the penguins of Antarctica are now endangered due to careless human mistakes such as oil spills. Most of this peril is due to the......

...category and discuss their uses. Metallic minerals are those minerals which can be melted to obtain new products. Aluminum is one of the most abundant metallic minerals on earth.  It is used in the production of automobiles, construction, electrical, machinery materials. Copper also a metallic mineral is used in building construction for things such as cables and heating pipes. Non-metallic minerals are those which do not produce new products upon melting. Clay for example is used in floor and wall tile as an absorbent. Also zeolites which are used in animal feed and kitty litter. Mining 1. How are minerals extracted from the Earth and processed? A technique called mining is the way that this minerals are extracted from the earth. Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef. In the mineral process valuable minerals are concentrated by removing needless materials from the rock material. The process involves reducing the size of the mineral. They do this crushers and grinding mills where the ore is broken down into smaller pieces. 2. What are the different ways minerals can be mined? Provide a brief description of at least three types of mining. Minerals are extracted from the earth surface and sub-surface. Open pit mining involves cuts that are made into the ground and the area at that depth is worked around. Once the minerals and waste have been......

Reconstructing the Past to Change the Future: an Analysis of Character Development in When Heaven and Earth Changed Places and Journey from the Fall

...Reconstructing the Past to Change the Future: An Analysis of Character Development in When Heaven and Earth Changed Places and Journey From the Fall While the characters from When Heaven and Earth Changed Places and Journey From the Fall move on to a life of "comfort and safety" in the US, unsettling memories of the war resurface that force them to revisit their pasts. In order to reconcile their regrets, they must reconstruct memories from their past and address their guilt. This essay follows the journey that the characters Le Ly Hayslip and Mai take from Vietnam to the US and provides examples of how the two women attempt to forget their previous existences, create new ones, and reevaluate their pasts in the context of the present. By “comfort and safety,” I mean that Le Ly and Mai are not worrying about survival and safety as much anymore in the US as compared to in Vietnam. The two characters escape Vietnam because the livelihoods of their families are at stake. Le Ly escapes Vietnam for reasons relating to physical as well as emotional well-being. When Le Ly talks about the story of a woman watching her son get shot and then the woman herself getting shot as well, Le Ly realizes that the only chance for survival for her and her son is by leaving Vietnam. In addition, not only is Le Ly in physical danger, she is also in a hostile environment in terms of her relationships with the people around her. Her family relations are extremely volatile, since her family is very...

Earth Perspectives

...EARTH PERSPECTIVES The biological and geological future of the Earth can be extrapolated based upon the estimated effects of several long-term influences. These include the chemistry at the Earth's surface, the rate of cooling of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity. An uncertain factor in this extrapolation is the ongoing influence of technology introduced by humans, such as geoengineering, which could cause significant changes to the planet. The current biotic crisis is being caused by technology and the effects may last for up to five million years. In turn, technology may result in the extinction of humanity, leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes. Hawking: How Humankind Will Survive the Future Listen, people of Earth: Everything's going to be fine. All we have to do is survive another century or two without self-destructing as a species. Then we'll get off this rock, spread throughout space, and everything will be all right. If this is not your idea of "optimism," then you are not Stephen Hawking. The esteemed physicist garnered headlines, and some eye-rolls, after telling Big Think last week that humanity needs to leave the Earth in the future or face extinction.

Mercury is made up of core-iron-nickel alloy, mantle, and then the crust which is silicate. During the day mercury’s temperature reaches 800°F and at night it goes down to -279°F. Mercury looks similar to earth’s moon; it is covered with craters which are made from meteors, asteroids, and comets and it covers 70% of mercury. Its diameter is 3,031 miles, its mass is 5% of earth’s mass, and the sun is 6.3 times brighter. Mercury was named by the Greeks, after the messenger of their g-d. Mariner 10 visited mercury, it mapped 45% of it, and it was the only one which visited more than one planet during its mission. It went up from Cape Canaveral, Florida on November, 1973 and went to Venus in February of 1974. Never attempt to observe Mercury or anything close to the sun with a naked eye because it can cause permanent damage. And with binoculars or telescope it is even more dangerous.

Earth Lodges

...fascinating artifact is called the earth lodge. Just as it sounds- an earth lodge was a lodge, or home, in the earth. Now it is not underground, but rather it is built using earth and wood for support. Shaped usually as a dome, the earth lodge held many people, as well as included a fire place, food storage, and even a space for animals such as horses. When analyzing the structure, it is clear that this place was home for many in the past. This structure had a place near the back for a shrine, most likely for prayer. The branches in the entrance typically symbolized an offering, since they were wrapped in trade clothes. The domes had a place for visitors to sit, which meant they were not always exclusive people. It is clear to see that these structures provided a home for many people in the past. Evaluating the decision to keep replicas of this type of housing development in North Dakota took no time at all. In today’s world; the Mandan, Hidatsa, and Arikara tribes still see the Earth Lodges as a sacred symbol of the past. It is obvious that these domes were used for centuries, and were important for the three affiliated tribes that used these types of houses. Keeping these houses ‘up and running’ is a great way to allow others to step into the past and see how others have lived before our time. It is relevant to our lives today because we can see first-hand how our ancestors lived long ago. Being able to see the structure of an earth lodge helps us compare......

...Have you ever wanted to die? Hopefully not and thanks to these two people we didn’t! 2 months ago a 2 boys named Kade Kostus and Kevin Durant met together at a basketball court in Miami ‘Florida, there was some crazy hot weathers and finally it happened. 2 girls from Japan have set bombs of in the earth’s inner core so most of the chemicals keeping us alive in the inner core have shot up in the sky and landed tall buildings. The buildings on the next day have fallen apart and killed about 3000 people in the city of Miami. Kade and Kevin met up again in Rockford Michigan and they talked about making a big ship that shoots underground so they could bag up the chemicals and place them back in the earth. That night the news channel comes to both of Kade and Kevin’s house interviewing them Kade said that “The chemicals have no name and we hope we don’t die”, on the other hand Kevin said “Ok we are leaving at 3:35 AM tomorrow and no further questions”. That morning Kade And Kevin has gone to their ship that they have built and it is placed in a secret island in Australia. The ship fires up with a super powered laser and spinning knives on the sides to keep moving fast down the earth’s layers. They finally hop in with the chemicals and the ship starts in 3 2 1 and poof. They have entered Lake Baikal because it has the thinnest crust so they could get a big boost in the mantle. They reach the crust and the crust has underwater volcanoes so it dents the ship. There...
