  • Last 100 Years The Global Temperatures
    1,143 words
    Greenhouse Effect The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. |The glass lets the sun light in to make heat but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts and climate changes which could alter our way of living. The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO 2), and methane whic...
  • Bipedalism In Hominids
    769 words
    Bipedalism: The Path to the Future Approximately 4 million years ago a wonderful evolutionary phenomenon was happening in Africa. Early hominids, man's ancestors, were beginning a giant leap in their evolution. These hominids were moving out of the forest and beginning to walk upright, out on the open plains (Fagan, 98). This change from quadrupedal ism was the most significant adaptation that ever happened to these early hominids. It caused many adaptations that make man what he is today. This ...
  • Same Apparent Strain And Gage Factor Change
    2,931 words
    ABSTRACT For accurately measuring thermal strains, particularly on large structures where welded strain gages cannot be used, a reversible bonded strain gage was developed. Basically it is a special poly imide strain gage which is same on both the base side and cover side so that it can be used both ways. It can be used to measure strains at temperatures under 250 oC (482 oF) of a structure made of aluminum alloys or composites (to which its difficult to weld a strain gage). These gages can be c...
  • Hcl To Diffuse Slower In The Tube
    1,857 words
    GAS LAWS KINETIC ENERGY / GRAHAM'S LAW LABChemistryBlock 8 April 20th, 2005 Purpose: To observe how masses of atoms and molecules affect their rate of diffusion, and explain our observations in terms of mass, velocity, kinetic energy and temperature. Warm-up Question: 1. What is the definition of temperature? Temperature is a measure of the average Kinetic Energy of the particles composing a material. 2. What is the definition of diffusion? Diffusion is a spontaneous spreading of particles until...
  • El Nino Year's Tropical Storms And Hurricanes
    2,677 words
    We live on an incredibly large planet. Even broader than the size of the planet are the amount of changes and relationships between humans, animals, environment, weather, and the affects of each. Many times with busy schedules and modern lifestyles we forget the interaction that goes on between any number of concepts or idea's. We fail to realize that a specific weather occurrence in the Pacific Ocean can have an affect on every day life in the United States. El Nino is one of the largest scient...
  • Restorative Materials And Prosthetic Devices
    957 words
    To improve the human identification process possibilities by the aid of forensic odontology. Particularly we considered to carry out an experimental study to learn more about the changes that dental remains, restorative materials and prosthetic devices undergo when exposed to very high temperatures, defining their behaviour and morphology with the aim to edit a reference table. In large scale disasters associated with fire the damage caused by heat can make medico-legal identification of human r...
  • Drastic Temperature Changes
    257 words
    The latest data confirm what a growing number of scientists have been saying for several years. The Earth's climate is rapidly changing. According to a report from the Smithsonian Institution and several other U.S. agencies, global temperatures increased by about one degree Fahrenheit over the course of the last century, and will likely rise even more during this one. Scientists predict that unless greenhouse gas emissions are reduced greatly, temperatures in the United States will rise by about...
  • James E Sea Level Rise Global Warming
    1,248 words
    Life is Changing Global warming is the most urgent environmental problem the world is facing. Few, if any, trends are more important to our future than climate change caused by human activities. This change is not beneficial. This warming trend occurring because of the buildup of greenhouse gases primarily carbon dioxide, methane, and nitrous oxide- which is a direct result of humans and the Industrial Revolution (EPA, 2000). These gasses are emitted profusely into the atmosphere by factories, c...
