  • Effects Of Acid Acid Deposition
    770 words
    Acid Rain is a type of air pollution, formed when oxides of sulfur and nitrogen combine with atmosphere moisture to yield sulfuric and nitric acids, which may then be carried long distances from a source before they are deposited by rain. This pollution may also be snow, fog, or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage for which it has been blamed, including eroding structures, injuring crops and forests, and th...

    The view of Christiaan Huygens, the Dutch mathematician and physicist who discovered Saturn's moon Titan in 1655, was as follows: Now can anyone look upon, and compare these systems (of Jupiter and Saturn) together, without being amazed at the vast magnitude and noble attendants of these two planets, in respect of this little pitiful Earth of ours? Or can they force themselves to think, that the wise Creator has disposed of all his animals and plants here, has furnished and adorned this spot onl...

    1,219 words
    From Water to Land (Revision) Abstract: The early tetrapods were the first vertebrates to actually walk the solid earth. They began their conquest of land in the Paleozoic era around 360 million years ago. The question many paleontologists have been asking for a long period of time is whether the anatomy for locomotion on land was developed in water for swimming purposes, or if it was adapted after the creatures became terrestrial. Recent findings of fossils indicate that the transformations of ...

  • Million Years Ago Dry Land
    722 words
    About four hundred and fifty million years ago, at the end of the Ordovician and in the beginning of the Silurian, the land was desolate and empty. Barren, hardly withered rock grounds, empty sand-, gravel- and clay plains, no green. Maybe some lichens. And at wet spots some algae with a couple of spider-like little creatures creeping around. In the neighbourhood of the mouth of rivers, where the water regularly flooded the land, it was probably green with algae. At such places, e. g. in Austral...

  • Extra Terrestrial Mars Planet

    My personal opinion I always wished that I would live long enough to witness the discovery of alien life on another planet. I guess a genie somewhere in this small world heard me and granted my wish, well sort of anyway. The discovery of these microscopic life forms on a rock that came from mars found in an Antarctic ice field in 1984 is amazing because we are now almost sure that life is or was possible on other planets than earth. Still, I wish that we would have found remains of an ancient ci...
