The sun loses little bits of energy because solar winds take atom parts (protons, and electrons) from it. Solar winds take over 1,000,000 tons worth of mass from the sun every second, but our sun’s mass is so much that this much mass is considered pretty much nothing. The sun’s heliosphere is taken over by solar winds. The solar winds have less and less pressure as it gets farther and farther from the sun. At 100 AU from the sun the solar winds cannot balance on their own because it is interstellar space.
But another article (Reuter, C:7) maintains that the effects of global warming are alr... ... middle of paper ... ...es on carbon based fuels and timetables for monitoring progress. It is therefore interesting to note how these issues were dealt with by the Clinton-Gore administration. The vice president did not discuss the issue at all after his inauguration. Many Clinton-Gore campaign promises were never fullfilled. Why?
Solar energy is created deep within the core of the Sun. It is here that the temperature (15,000,000° C; 27,000,000° F) and pressure (340 billion times Earth's air pressure at sea level) is so intense that nuclear reactions take place. This reaction causes four protons or hydrogen nuclei to fuse together to form one alpha particle or helium nucleus. The alpha particle is about .7 percent less massive than the four protons. The difference in mass is expelled as energy and is carried to the surface of the Sun, through a process known as convection, where it is released as light and heat.
Like most gaseous elements it is diatomic (its molecules contain two atoms), but it dissociates into free atoms at high temperatures. Hydrogen has a lower boiling point and melting point than any other substance except helium. Liquid hydrogen, first obtained by the British chemist Sir James Dewar in 1898, is colorless (but light blue in thick layers) with sp.gr. 0.070. when allowed to evaporate rapidly under reduced pressure it freezes into a colorless solid. Hydrogen is a mixture of two allotropic forms, orthohydrogen and parahydrogen, ordinary hydrogen containing about three-fourths of the ortho form and one-fourth of the para form.
This makes it the second most common element behind hydrogen. Helium is mostly concentrated in stars where it combines with hydrogen to create nuclear fusion. Helium is created in stars by nuclear fusion of hydrogen. Helium is found on the Earth as well, but it is not as abundant as it is in space. Only 0.0005 percent of helium occurs in the Earth's Atmosphere, as opposed to 23 percent in space.
The temperature of the corona is so high that the gravity of the sun cannot hold on to it, so hot charged particles from the corona regularly fly off the sun at millions of miles per hour. When these particles collide with atoms in the earth's atmosphere, they excite their electrons, causing them to "jump" to a higher energy level. When electrons jump to a h... ... middle of paper ... ...solar maximum), less cosmic rays strike the earth, and when it is weak (during a solar minimum), many cosmic rays strike the earth. Trees record in their rings how much carbon 14 is in the atmosphere, and during the Maunder Minimum tree rings had very high levels of Carbon 14. Thus, there seems to be a link between the sunspot cycle and the climate of the earth, with solar minimum bringing cooler temperatures and solar maximum bringing warmer ones.
Human CFCs are insoluble, and can therefore rise to the ozone layer where they can do their damage. Do man-made chlorofluorocarbons (CFCs) destroy the ozone layer? There are no longer any skeptics left at NASA, the National Academy of Sciences, the National Center for Atmospheric Research, or the World Meteorological Organization. In fact, the three scientists who first sounded the alarm in the early 80s -- F. Sherwood Rowland, Paul Crutzen and Mario Molina -- received the 1995 Nobel Prize in chemistry for their work. In 1991, NASA launched the Upper Atmosphere Research Satellite (UARS) in an attempt to determine once and for all if humans were responsible for causing this serious damage to the atmosphere.
Plasma : Plasma is an ionized gas which consists of electrons, ions and neutral particles which show two specific behaviour. • Quasi neutrality • Collective behaviour Ionosphere : It is an example of plasma. Ionosphere is important, because of the long distance communication through radiowaves. • It is a region in the upper atmosphere in which gases are ionized due to UV radiation from the sun. The ionosphere region extends from about 50 km to 1000 km above the earth.
The rotation on Venus is somewhat unusual because it is very slow and also retrograde. One day on Venus is equivalent to 243 days on Earth. The atmosphere on Venus is composed almost entirely of Carbon Dioxide. It contains several layers of clouds made up of sulfuric acid. These clouds completely cover up our view of the planet.
The distance from earth to the sun is 150,000,000 km or 1AU (Astronomical Unit). Earth is not like any other planet in the solar system. earth has enough water and oxygen for us to live. Earth can protect us from many things like the effects coming from the sun’s intense radiation. It causes meteors to burn up before they reach earth’s surface.
