  • 8. Buildings built on permafrost may collapse when the heat generated by the building thaws the ground. The photo above is an example of what can happen to a building built on ground that is permanently frozen. Houses in Siberia are often built on stilts so this will not happen. http://henkbinnendijk.tripod.com/sitebuildercontent/sitebuilderpictures/dawsonpermafrosthouses700x460.jpg Used with permission

    • The Aral Sea is becoming a desert because water is being diverted from rivers that feed it. The diverted water is being used to irrigate the cotton fields in Uzbekistan.
    • The wind blows the sand, which is contaminated with fertilizers and pesticides, into the nearby villages, where it causes serious illnesses.
    • The Sea is so polluted from run-off that the fish have died.
  • 10. irrigation To irrigate is to supply (dry land) with water by means of ditches, pipes, or tubes. http://www.iwmi.cgiar.org/slides/Prfiles.htm No copyright

  • 12. Other factors that influence the geography of Russia and Central Asia
    • Many rivers flow northward into the Arctic Ocean. They are frozen most of the year.

    • St. Petersburg is the “window to the West” and gives the Russians a port on the Baltic Sea.
