Transcript of "Chapter Two, Section 2"

  1. 1. Chapter 2, Section 2
  2. 2. The Reality of the H 2 the IS 0! <ul><li>No freshwater, no saltwater = no life </li></ul><ul><li>Water supports plants, animals </li></ul><ul><li>Helps distribute heat on earth </li></ul>
  3. 3. Oceans and Seas <ul><li>Salt water covers 71 % of planet </li></ul><ul><li>(60 % of Northern Hemisphere, 81% of Southern Hemisphere) </li></ul><ul><li>Atlantic, PACIFIC, Indian, Arctic </li></ul>
  4. 4. Ocean Motion <ul><li>Salt water circulates through 3 basic motions: </li></ul><ul><li>Currents - act like rivers flowing through ocean </li></ul><ul><li>Waves - ridges produced by winds </li></ul><ul><li>Tides - rises and falls of the ocean created by gravitational pull of moon or the sun </li></ul><ul><li>Oceans help distribute heat on the planet; winds blow over ocean and are either heated or cooled by water, then blow over land, which moderate temperature of air over the land </li></ul>
  5. 5. HYDROLOGIC CYCLE
  6. 6. Hydrologic cycle: what happens? <ul><li>Water evaporates into the atmosphere from oceans, bodies of water, and plants (the water exists in atmosphere as vapor) </li></ul><ul><li>Vapor cools, condenses, and falls to earth as precipitation, rain, or snow </li></ul><ul><li>Water soaks into the ground, evaporates to the atmosphere, or flows into rivers to be recycled </li></ul>
  7. 7. Lakes, Rivers, and Streams <ul><li>Lakes = 95% of all earth’s fresh water supply </li></ul><ul><li>Largest --Lake Baikal in Russia (totaling 18% of all freshwater on earth) </li></ul><ul><li>Freshwater lakes are result of glacial action thousands of years ago </li></ul><ul><li>Saltwater lakes result from changes in earth’s surface that cut off outlets to the sea - form when creeks and rivers carry salts, but no outlet </li></ul><ul><li>Largest salt lake: Caspian sea --Western Asia </li></ul>
  8. 8. Un poco mas… <ul><li>Drainage basin: an area drained by a major river and its tributaries </li></ul><ul><li>Ground water: water held in the pores of rocks </li></ul><ul><li>Water table: level at which the rock is saturated - can rise or fall depending on amount of water pumped out of ground </li></ul>
  9. 9. Activity: IDENTIFY THIS and THAT <ul><li>Now, turn your book to page 34 and 35. Mr. Philen is going to show you a variety of pictures of landforms, identify them… </li></ul>
  10. 18. What landforms exist in Senegal? In Africa? <ul><li>How could we draw a landform map for Senegal? </li></ul><ul><li>What elements would we include? </li></ul>
  11. 19. Continental Landforms <ul><li>Relief: difference in elevation of a landform from its lowest point to its highest point </li></ul><ul><li>Four categories: mountains, hills, plains, plateaus </li></ul>
  12. 20. Continental Landforms you need to know <ul><li>Volcano -mountain </li></ul><ul><li>Strait -valley </li></ul><ul><li>Island -glacier </li></ul><ul><li>Cape/peninsula -cataract </li></ul><ul><li>Bay -canyon </li></ul><ul><li>Swamp -cliff </li></ul><ul><li>Flood/plain -plateau </li></ul><ul><li>Marsh -mesa </li></ul><ul><li>Oasis -prairie </li></ul><ul><li>Steppe </li></ul>
  13. 21. Oceanic Landforms <ul><li>There are landforms similar to the land on the sea floor </li></ul><ul><li>Continental shelf - earth’s surface from edge of a continent to the deep part of the ocean </li></ul><ul><li>Ocean floor contains ridges, valleys, canyons, plains </li></ul><ul><li>Longest: Mid-Atlantic Ridge </li></ul><ul><li>Islands can form from volcanic action </li></ul>
  14. 22. Questions for thought <ul><li>1) How do the winds and the ocean distribute heat on the earth’s surface? </li></ul><ul><li>2) Why is water such a valuable renewable resource? </li></ul><ul><li>3) Describe what happens with the hydrologic cycle. </li></ul>
