...One hot summer morning a little Cloud rose out of the sea and floated lightly and happily across the blue sky. Far below lay the earth, dry, from drought. The little Cloud could see the poor people of the earth working and suffering in the hot fields, while the cloud floated on the morning breeze, without a care. "Oh, if I could only help the poor people down there!" she thought. "If I could but make their work easier! And as the day passed, and the Cloud became larger, this wish to do something for the people of earth was ever greater in her heart. On earth it grew hotter and hotter; the sun burned down so fiercely that the people were fainting in its rays; it seemed as if they must die of heat, and yet they were obliged to go on with their work, for they were very poor. Sometimes they stood and looked up at the Cloud, as if they were praying, and saying, "Ah, if you could help us!" "I will help you; I will!" said the Cloud. And she began to sink softly down toward the earth. The thought made her suddenly marvelously big and strong and powerful. Never had she dreamed that she could be so big. Like a mighty angel of blessing she stood above the earth, and lifted her head and spread her wings far over the fields and woods. She was so great, so majestic, that men and animals were awestruck at the sight; the trees and the grasses bowed before her; yet all the earth creatures felt that she meant them well. "Yes, I will help you," cried the Cloud once more. "Take me to yourselves;...

...There is a wide misconception that aerosols are bad for the environment and contribute to the depletion of the ozone. Aerosol (derived more or less from “air-solid”) is technically just the suspension of fine particles, such as solids or liquid droplets, in a gas. As such, clouds, smog, smoke, air born dust, etc. are all aerosols. About 90% of all aerosols are naturally produced . They can either be directly emitted into the atmosphere (primary aerosol like dust, sea salt and black carbon), or they can be formed in the atmosphere by condensation (secondary inorganic aerosol such as sulfates, nitrates and ammonium). Aerosols are argued to be cooling the surface of the earth. This is relevant because the effects of aerosols may have beneficial or possibly dire consequences. Aerosols play a large role in cooling the surface of the earth, counteracting global warming, medicine, and therefore nothing should be done to eliminate them. Many types of aerosols have a cooling effect on the Earth, such as the aerosols produced from the burning of fossil fuels. The aerosols produced from this are known to partially counteract global warming caused by various greenhouse gases. In order to say that aerosols cool the earth, we have to explore the different theories on how they are said to do so. According to Jeffrey T. Kiehl in "Solving the Aerosol Puzzle" the burning of fossil fuels and biomass (in natural and man-made fires) leads to the production of substantial amounts of aerosols in the...

I think it was the one facing more starboard. I always get myself mixed up when I go into that module; I can never easily find the hatch again. It is completely night. There are thunderstorms across Africa and lightning is everywhere; bright flashes are going cloud to cloud illuminating the clouds as it arcs from one to the other. It is a private fireworks show. The storm is large and very spread out and at any moment you see 4 or 5 flashes occurring at one time, each one only lasting a moment. The colors range from something orange-ish to blue-white. Some are more like balls of light while others have that characteristic streak shape that you can observe on Earth. It goes on for several minutes. Occasionally a city goes by with lights shining brightly against the backdrop of flashing pulses of light. The cities come in all shapes, sizes and colors and light patterns. Some cities have clouds over them and all that can be seen is a haze of light. For the cities with clear skies, street patterns are apparent...

...Comparative Essay: Original creation of the Earth PHSC 210, D03-LUO I. Introduction The old-Earth evolution and young-Earth creation debate has been one that has gone on for centuries. Each viewpoint seeks to give an answer to life’s most difficult questions or origins and how the Earth came to be what it resembles today. While the Young Earth viewpoint has remained constant and unchanged throughout the centuries the Old Earth view seems to be continually evolving as new discoveries tend to discredit previous assumptions. One certainty is that both viewpoints take a dogmatic stance against each other in regards to the interpretation of scientific evidence. The purpose of this paper is to compare old-Earth and young-Earth viewpoints on the original creation of the Earth. II. Old-Earth Secular View The old-Earth evolution viewpoint on the original creation of the Earth is the nebular hypothesis. This viewpoint gave birth to evolutionary thought concerning origins. “…the history of evolution did not begin in 1859 with Charles Darwin’s ‘Origin of Species,’ but with the publication in 1796 of Pierre Simon Laplace’s so-called nebular hypothesis” (Numbers. 1977). This viewpoint suggests “About 4.6 billion years ago our solar system formed from a cloud of gas and dust which slowly contracted under the mutual gravity of all of its particles” (The Solar Nebula. N.d.). It is believed that this cloud of gas and dust was spinning at an accelerated rate and...

The surface of Venus is surrounded by an opaque layer of clouds made up of sulfuric acid. Venus is also known as the hottest planet in our solar system. The average surface temperature of the planet is 462 degrees celsius, but also Venus does not have a tilt on it’s axis, so therefore there is no seasonal variation. The atmosphere around the planet is 96.5 percent of carbon dioxide that traps...

...think it is man-made but fail to understand the fascinating natural cycles of how complex the geological history of planet earth is. It is a difficult subject to take in, so the public has to rely on experts for making the information understandable. The problem with relying on a group of people to make decisions for the public is they have the ability to manipulate the data to back their point of view. It has been scientifically proven and accepted by many scientist that mini global warming and global cooling periods have been present in the earth’s history. These fascinating scientific facts of earth’s history have been totally knocked out by the massive hype that man is responsible for climate change. Overall, climate change tends to be reported as explanations about general tendencies and possible outcomes. Climate Change is a Natural Process, not Man-Made It seems like everyone in the world has an opinion about what might be causing the climate of the world to change. Recently there has been a common scientific consensus that claims to know what is causing the climate to change. The Intergovernmental Panel on Climate Change (IPCC) is stating carbon dioxide is causing the climate to change, the oceans are warming, and the temperature is rising faster than usual. These claims being made are not only incorrect but lack the understanding of how the earth has hosted life for billions of years. There are many different claims about climate change being a man-made challenge facing...

...ASTRONOMY | The earth solar system was form by the disturbed, or maybe by an explosion of close by star called the supernova. The explosion or the disturbed of stars causes wave in space which caused the squeezing of gas and dust clouds. The squeezing of the clouds stared to collapse, as gravity act force dust and gas clouds together which forms the solar nebula. Soon the dust and gas become hotter and dense in the middle; later a disc of gas and dust was surrounding the explosion in the middle. As the disc became thinner, dust particles stared sticking together form clumps. Most clumps was big, other were small. Those began forming planets and moons. Near the middle also were Earth form, some particles could stand that heat. Cold particles move to the outer area of the disc, where Jupiter formed. As particles still began to form, the middle had got very hot that it became a star (sun). The Earth’s orbit is not a complete circle. The Earth orbit is elliptical, that’s causing the distance from Earth to the sun changes throughout the year. When the Earth closet to the sun on its orbit it’s about 91,445,000 miles away. But when Earth is far from the sun on its orbit it’s about 95,555,000 miles away. But the average distance from the sun to the Earth is about 92,955,807 miles away. Since the Earth’s orbit is not circle but it’s elliptical it affects us on how much of solar energy we will be getting. The planet we live on is called Earth; Earth is the third planet from...

...The Swing How do you like to go up in a swing, Up in the air so blue? Oh, I do think it the pleasantest thing Ever a child can do! Up in the air and over the wall, Till I can see so wide, River and trees and cattle and all Over the countryside-- Till I look down on the garden green, Down on the roof so brown-- Up in the air I go flying again, Up in the air and down! Robert Louis Stevenson Because I Could Not Stop for Death( personification) Top of Form Because I could not stop for Death, He kindly stopped for me; The carriage held but just ourselves And Immortality. We slowly drove, he knew no haste, And I had put away My labour, and my leisure too, For his civility. We passed the school where children played, Their lessons scarcely done; We passed the fields of gazing grain, We passed the setting sun. We paused before a house that seemed A swelling of the ground; The roof was scarcely visible, The cornice but a mound. Since then 'tis centuries; but each Feels shorter than the day I first surmised the horses' heads Were toward eternity. The poem by Emily Dickinson "Because I could not stop for Death" is know to be one of the best poems in English. Every image extends and intensifies each other. But there are some pro and cons in this poem. The poem helps us to characterize and bring death down to a more personal level. It shows a different perspective of death that the more popular views of death being brutal and...

...Abstract Eight planets, fifty-eight moons, thousands of asteroids, and billions of meteoroids and comets and one dwarf planet named Pluto orbit the grand star, the Sun. Around and around they go. These planets and other object came from a huge explosion. The Big Bang Theory, which states that the universe began as a dense and hot point that was less than a fraction of an inch and has continued to evolve into what it is known as of today. The origin of the galaxy seems a mystery. But over time, the pieces of the puzzle are coming together. Scientists believe a supernova or star may have formed the universe. When the Earth first formed, it contained gasses which dissolved into the Earth’s molten planet. When this formation happened from the smaller bodies, these were called planetesimals. But not all planets are the same. The Jovian planets are shrouded by thick atmospheres that are rich in hydrogen and helium. These planets were formed away from the sun. A shooting star is what individuals think of when they see a vapor stream of dust and gas shooting across the sky. The sun helps make this spectacle possible and could be a reason why early astronomers were so curious about the skies. When an individual looks up at the night sky, he or she can get lost in the vast beauty. Who wouldn’t get mesmerized?

...These fascinating rings have puzzled astronomers since 1610 when Galileo Galilei discovered them. They can be seen with a very low-powered telescope. The rings measure about thirty feet in thickness. Which is not very much compared to the entire size of Saturn. They are made up of billions and billions of ice and rock chunk particles, all traveling at their own orbit around it. These rings are made up of rock pieces that also create a rainbow effect as they refract the light from the sun. These rings also increase the brightness of Saturn, making it even more visible with the unaided eye. Although, from Earth, the rings look like they are divided from each other by thin, dark regions. These regions are called the Cassini division and the Encke Division. The rings particles vary from the size of dust particles to about the size of a house. The two outer rings have a very strong magnetic field. Each of the sections of rings, travel at different speeds around Saturn. Saturn has seven different groups of rings, these groups are divided by divisions. All of the different rings are named in alphabetical order, in order from when and where they were located. The order doesn’t actually go in the actual order of the alphabet in which most people would expect it to go. It goes from the inside ring to the outside ring. The order of rings is D, C, B, then...

...bright torch of heaven.” Istar was regarded as being responsible for the world’s fertility. There was a legend formed about Istar that she went to the Underworld to search for her dead lover Tammuz, and all life on Earth started to die. The gods intervened and revived Tammuz and Istar was restored to the world. The Greeks called these two bodies Phosphorus and Hesperus, and the Romans called them Lucifer and Vesper. Both the Greeks and Romans practiced Venus-worship and erected temples in her honor. Venus-worship continued up until very recent times. It was believed that at one point Venus might have been a tropical paradise. Only when radio mapping was developed in the 1960’s were scientists actually able to observe and measure the extreme temperatures and hostile environment through the dense cloud of sulfuric acid. It’s thought that Venus might have had oceans but they evaporated as the planets temperature...
