..., the current heats the atoms up. A thinner conductor heats up more easily than a thicker conductor because it is more resistant to the movement of electrons....Bound electrons in the vibrating atoms may be boosted temporarily to a higher energy level. When they fall back to their normal levels, the electrons release the extra energy in the form of photons. Metal atoms release mostly infrared light photons, which are invisible to the human eye. But if they are heated to a high enough level -- around 4,000 degrees Fahrenheit (2,200 degrees C) in the case of a light bulb -- they will emit a good deal of visible light.” (Source: how stuff works, how light bulbs work, 2011). Thus, a tungsten filament in an incandescent lamp...

...pride in its immense ancient volcano that is three times the altitude of Mt. Everest and the seemingly 'grand canyon' land form which must have had some geological activities as evidenced with the way it looks in the presentation aided by the special apparatus in space. Similarly, an asteroid is shown to be enormous, typically irregular elongated rubble mentioned to have broken down on Earth as meteorites which are essentially found as materials that had come together at the rate of 80,000 kilometers per hour to form planets including the Earth. By dating a meteorite fragment thus, humans have come to determine how long this living planet has lived....

...? EARTH SCIENCES & Section Number of EARTH SCIENCES: - Discuss the formation and types of fog. Fog is termed as the collection or accumulation of dewdrops (water droplets) which are present in the earth’s atmosphere (Ahrens, 1991). It is important to know that fog is a typical form of a cloud but the term “Fog” is used to differentiate the thin-line difference between a cloud and a fog. A fog is a result of the water vapors accumulated from the water sources present on the ground like a lake or marsh bodies as well as the ocean which give rise to fog. In other words, they are low-lying clouds (Allred, 2009). Formation of a fog depends on...

...deplete a limited resource that is causing great devastation on the entire planet. We should be directing our combined efforts into developing alternative energy sources for everyone, regardless of nationality and land boundaries. If we spent today on global warming research and development what is spent on defense and security for our nations, we would solve the energy crisis and have a peaceful planet upon which to live. Instead, we move from spending and fighting to temporary solutions to a permanent problem. Global warming is an international threat far more serious than any war or military group. The effects of global warming upon the quality of life for our planet is a devastating disaster that is just waiting for...

..., in which the continents all came from a single land mass, called Pangaea, and drifted away from one another through time. Initially, it broke up into Laurasia and Gondwana, which will later form into Africa, South America, India, Antarctica, and Australia. Plate tectonics, on the other hand, theorizes that new Earth surface is formed along oceanic crusts in between two diverging plate boundaries, while on converging boundaries, the plates are being pushed together or pulled apart, thus forming troughs or mountains. Activity along the plates may also cause what we now call as earthquakes (http://wapi.isu.edu/geo_pgt/Mod04_Earth/mod4.htm). Through time...

...been extracted. It is the largest contributor to environmental concerns associated with mineral extraction since it forms large debris that is not easily disposed. They also contaminate water meant for commercial and domestic use when it comes into contact with. This is because it has other dangerous minerals which mix with water to form a harmful compound to animal and plant life (Middleton, 2003 p 56)2. Other gases are released to the atmosphere causing air pollution. Occurrences The earth is made up of three components; the air (atmosphere), water (hydrosphere) and land (lithosphere). Minerals form part of the soil underneath our feet. There are...

...by the Earth’s bovine population have an even greater impact upon overall CO2 levels than all human activity within any given year. However, this should not be seen to delegitimize the processes whereby humans can provide additional negative impacts upon the global environment. Due to the fact that the Earth is ultimately a closed system, it can only integrate a certain amount of change before negative impacts are seen. As such the Earth’s ecological system might be able to integrate with volcanic eruptions or the methane gas produced by cows; however, further integration of the ever-increasing levels of human CO2 emissions is likely well beyond the capabilities of the system as a whole....

...Earth Science This success story belongs to the time when the Empire Building in New York went green, one window after the other. It was amonumental task especially because it involved replacing each of the 6,514 windows which amounted to more than 26,000 panes of glass. The going green debated basically meant that the Empire State Building was ready for an overhaul. Since this is a very old structure, nothing of this stature has ever taken place. It has made people realize that almost anything is possible if the willpower is there. From an environmental perspective, it gives the commoners food for thought that if they apply themselves whole-heartedly towards the cause of the environment, there would be...

There are hills and areas of higher land, as are shown in the relief map below but this is simply because these parts of the sedimentary rocks, which include limestone, dolomite, shale, sandstone, and siltstone, although they tip to the south west ,were always higher in elevation than the intrusive ice sheets. This is especially so in the north east of the state, although the highest point is actually in the south in Wayne County, near to the state’s eastern border. The rock there is the oldest in date ,being from more than 440 millions years ago. according to Indiana University , Department of Earth...

...The Geology of Shanghai, China The Geology of Shanghai, China Introduction From the dawn of human civilization, mankind has been fascinated with the geology around us. Earth, in fact, is one of the four essential elements that sustain life, according to ancient philosophy. By examining the geology around us, we can learn a great deal about our history. We can gather the way our ancient ancestors lived, what types of conditions they lived through, and how the earth around us has changed through the centuries, just to name a few items. The land in our community can also help us understand the types of people who walked...
