Carbon Dioxide Greenhouse Effect
1,080 wordsWhile some people believe the earth's climatic changes are due to the fact that the universe is getting older, others believe it is due to the greenhouse effect. The greenhouse effect is a naturally occuring phenomenon that is responsible for trapping heat near the earth's surface and keeping the planet warm. It is called the greenhouse effect because the way it works is similar to the way in which a green house functions. In a greenhouse sunlight passes through the transparent roof and walls an...

Lava Flows Earth Crust
1,090 wordsVolcano: defined is a mountain or hill formed by the accumulation of materials erupted through one or more openings (called volcanic vents) in the earth's surface. The term volcano can also refer to the vents themselves. Most volcanoes have steep sides, but some can be gently sloping mountains or even flat tablelands, plateaus, or plains. The volcanoes above sea level are the best known, but the vast majority of the world's volcanoes lie beneath the sea, formed along the global oceanic ridge sys...

Ultraviolet Radiation Ozone Layer
1,027 wordsGreenhouse Effect On a bright, cool day, most people notice the sun's rays as feeling good on their skin. By nature, many of us even try to stay on the sunny side of the street while walking. The sun is 93 million miles away from earth and its energy travels to us in moving waves called radiation. The energy becomes heat, light and other energy too. Visible sunlight allows us to see the world around us, but there is invisible sunlight, too. These rays can't be seen, but some can be felt as heat....

Surface Of The Earth Earth Surface
2,510 wordsIn giving to the treatise here announced the name of an Essay on the Theory of the Earth, the Editor has taken a liberty that is certainly not warranted by the original. The title of the French work makes no mention whatever of the theory of the earth. The fact is, that M. CUVIER having published, in the Annales de Museum, a succession of memoirs on the fossil remains of animals found in the strata around Paris, (of which an account was given in the 20 th vol. of this Journal), was very naturall...

Air Pressure Middle Ear
444 wordsAir is composed of molecules. Air is matter. It has mass and takes up space. Air is composed of different gases such as nitrogen, oxygen, carbon dioxide, water vapor, and other gases. Air molecules are in constant motion. As they move, they come in contact with surfaces. Air molecules push and press on the surfaces they contact. The amount of force per unit area that air molecules exert on a surface is called air pressure. (What is Air Pressure 6) Air pressure is caused by all of the air molecul...

Tectonic Plates Oceanic Crust
1,370 wordsThe core is divided into two parts, the solid inner core and the liquid outer core. The inner core is thought to be solid and primarily made up of iron and some nickel. The outer core is all around the inner core and is believed to be made up of liquid iron mixed with liquid nickel. The outer core is about 2890 to 5100 km. The inner core is 5100 to 6378 km. Earths mantle is mainly composed of substances high in iron and magnesium. The melting point of every substance depends on the pressure and ...

Carbon Dioxide Methane Renewable Energy Sources
1,623 wordsBy the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since the end of the dinosaurs, some 65 billion years ago. If we stay at the rate we our now (fossil fuel consumption / growth in population) then within the next two century the Earth's air might not be fit to breath. Many people in the world do not think that this is a major concern and that it is normal for the Earth's temperature to incr...

Millions Of Dollars Plate Tectonics
1,068 wordsEARTHQUAKE REFERENCE FILES Earthquake, shaking of the earth's surface caused by rapid movement of the earth's rocky outer layer. Earthquakes occur when energy stored within the earth, usually in the form of strain in rocks, suddenly releases. This energy is transmitted to the surface of the earth by earthquake waves. The study of earthquakes and the waves they create is called seismology. Scientists who study earthquakes are called seismologists. (Webster's p. 423) The destruction an earthquake ...

Surface Tension Earth Surface
1,468 wordsWater Today Nearly three fourths of the Earth's surface is covered with water. Human life, as with all animal and plant life on the planet, is dependent upon water. Not only do we need water to grow our food, generate our power and run our industries, but we need it as a basic part of our daily lives - our bodies need to ingest water every day to continue functioning. Communities and individuals can exist without many things if they have to - they can be deprived of comfort, of shelter, even of ...

Theory Of Evolution Darwin Theory
789 wordsBorn in Shrewsbury, Shropshire, England, on February 12, 1809. After graduating from the elite school at Shrewsbury in 1825, Darwin went to the University of Edinburgh to study medicine. In 1827 he dropped out of medical school and entered the University of Cambridge, in preparation for becoming a clergyman of the Church of England. There he met two figures: Adam Sedgwick, a geologist, and John Stevens Henslow, a naturalist. Henslow not only helped build Darwin s self-confidence but also taught ...

Number Of Deaths Earth Surface
537 wordsEvery year there are about a million earthquakes. Fortunately, not all of them are destructive. The intensity of an earthquake is measured on the Richter Scale, which goes from zero upward. Major damage generally occurs from earthquakes ranging from 6. 0 upwards. The damaging earthquakes also occur either in the narrow belt, which surrounds the Pacific Ocean or in a line, which extends from Burma to the Alps in Europe. Earthquakes are one of natural wonders of the world that cause the most death...

Carbon Dioxide Emissions Parts Per Million
2,377 words1. What are the Greenhouse Gases? Carbon dioxide (CO 2) is responsible for more than half the human contribution to the greenhouse effect, and concentrations have climbed steadily from around 280 parts per million at the dawn of the industrial revolution meaning 0. 028 percent of the air s volume is taken up by the gas to around 355 ppm today. As people burn oil, coal and natural gas, they release carbon that ancient plants in past geological ages absorbed and stored. 6 As cement workers process...
