Continental polar (cP) or continental arctic (cA) air masses are cold, dry, and stable originating over northern Canada and Alaska as a result of radiational cooling. (Oklahoma Climatological Survey, 2004)"
The greenhouse effect has been in the news for the last several decades especially with the resulting negative effects it has on climate change and global warming. Generally, the greenhouse effect is a naturally occurring phenomenon that contributes to the survivability of living organisms here on Earth. The earth's atmosphere contains trace gases, some of which absorb heat. These gases (water vapor, carbon dioxide, methane, ozone, and nitrous oxide) are referred to as greenhouse gases. (University Corporation for Atmospheric Research, 2010) The inability to absorb heat produces abnormal environmental and climatic conditions because the equilibrium has been imbalanced due to over production and release of greenhouse gasses in the atmosphere. Earth is not the only planet that has a greenhouse effect but other planets as well particularly Venus and Mars. Whereas the Earth's greenhouse effect brought balance that made the planet livable, Venus and Mars are extremes where the former is extremely hot and the latter is very cold. The greenhouse gasses serves as an insulating blanket for the Earth's atmosphere and has "just the right thickness, trapping sufficient solar energy to keep the global average temperature in a pleasant range. The Martian blanket is too thin, and the Venusian blanket is way too thick. (University Corporation for Atmospheric Research, 2010)"
4. General Earth Science WA-5
Stars are celestial bodies in the universe found in various solar systems and these produce intense heat and bright light. In our solar system, the most prominent star is the sun and is made up of "94% hydrogen, 6%, and 0.13% of oxygen, carbon, and nitrogen. The Sun also has traces of neon, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, potassium, and iron. (Strobel, 2011)" Although the sun produces intense heat, there are cooler regions therein and the cold regions of the sun are known as sunspots. Aside from being colder relative to the general heat intensity of the sun, sunspots "are regions of strong magnetic fields. This affects the spectral lines in the sunspot spectral. Hundreds of years of observing the sunspots on the Sun show that the number of sunspots varies in a cycle with an average period of 11 years. (Strobel, 2011)" Sunspots and the 11-year cycle have effects on human behavior and activities. In one study by Russian scientist A.L. Tchijevsky, "he discovered that the solar minimum is the lag period when repression is tolerated by the masses, as if they lacked the vital energy to make the needed changes. He found that during the sunspot maximum, the movement of humans is also at its peak. (Borges, 2000)"
"The determining factor for categorizing the star is its mass. Any star less than about three solar masses (one solar mass is the mass of our sun) will spend almost all of its life transiting what is called the 'main sequence.' About 90% of all stars are like this. (Mihos, 2006)" Aside from categorization based on mass, there is the life cycle of the star where it starts of as a giant at the beginning of the life cycle and ends up as a dwarf when the end of life is near. This also means that giant stars are at their hottest temperatures and dwarfs stars are in their cooling or dying off period. Often, dead stars turn into black holes especially those that collapse and retained more mass. Aside from originating from dead stars, "black holes are the densest, most massive singular objects in the universe. Formed in one of three main processes, they exert so much gravitational force that nothing - not even light - can escape their pull. Since nothing can ever come out, it is called a hole. Since not even light nor other electromagnetic radiation can escape, it is called a black hole. (Mihos, 2006)" Our solar system has at its center the sun and there are the planets surrounding this star. The planets are divided into two categories: Jovian and terrestrial. Mercury, Venus, Earth, and Mars became the rocky, terrestrial planets of the inner solar system, while Jupiter, Saturn, Uranus, and Neptune became the gas or Jovian giants of the outer solar system (Mihos, 2006).
5. Living in the Information Age WA-2
Search engines are invaluable tools of the Internet especially those using these technologies to conduct research. Like any other tool or application, some tools are better than others and there are also specialized and generalized tools or applications. For instance, while using Google search engine and EBSCO using the keywords "privacy and security on the Internet," Google produced hits totaling 316,000,000 while EBSCO did not even come close...
Here, the mass of water is being pulled upward toward the atmosphere by its attraction to the moon. As it does so, the tide is pulled inward from the coastlines contained the body of water. As the moon moves closer to the earth during its daily rotation, the magnetic pull lessens. The diminished pull causes the bulge to decline, pushing the body of water outward and extending the coastlines. It
Earth Science Probably one of the biggest and longest fought wars between science and religion has been on the subject of whether the earth was created, as science says, with a massive explosion known as the big bang or within a span of six days as religion teaches us. Science looks into and probes at what is majorly unknown and religion has always done better than that. This paper will discuss
The Moon is believed by many to have been part of the earth and that it was tore off as a result of an initial spin that was too great to hold the planet together. One of the prevailing theories was that involving an impact of large magnitude involving the newly formed Earth and a giant object of the size of Mars hitting Earth and blowing up material that
Essentially, it is a systems theory that sees systems that are apparently disorganized (that is unpredictable because of the large amount of variables) as systems that do have order, it is just complex and we need to find it. Some call it the butterfly effect due to that the flapping of a butterfly's wings in China might have an effect on Peru's weather. Even the most sophisticated computers cannot
IX. Teacher presentation The teacher's presentation in inquiry-based learning must be one that presents questions to the students. This can be best achieved through an interesting presentation that requires students to actively and fully participate in that which is being presented by the teacher. Capturing the classroom attention in this activity may be easily accomplished through filling a basket or box with oddities relating to earth science and to one-by-one pull
Earth Like Solar Planets Throughout the course of human history, astronomers have wondered about the possibility of finding life beyond the solar system. In the last 20 years, there has been more of an emphasis on identifying other earth like celestial bodies that are orbiting distance stars. This has been taking place through the launch of various orbital telescopes such as: Kepler. Monitoring over 150 thousand stars, Kepler is identifying earth
