  2. 2. Minerals - some minerals are very rare and some exist in great quantities. (pg 40-43, 48-53) <ul><li>Definition : A naturally formed inorganic( non living) solid that has a definite crystal structure </li></ul><ul><li>Examples : coal, gold, copper, fluoride, limestone, bauxite-makes aluminum </li></ul>
  3. 3. Minerals <ul><li>How can we reduce the rate of depletion of minerals? </li></ul><ul><ul><li>1) recycling-Use the recycling bins </li></ul></ul><ul><ul><li>2) Use substitutes like glass or plastic bottles instead </li></ul></ul>

  5. 5. New Webs <ul><li>Read 64-69, 74-79 </li></ul>
  6. 6. Weathering <ul><li>Breaking down of rocks and other materials on Earth’s surface by such processes as rain or wind. </li></ul>
  7. 7. Erosion <ul><li>The process by which the products of weathering are moved from one place to another. </li></ul>

Soil’s texture and what it is made up of (composition) is influenced by plant roots, debris, worms, insects, funguses, and other things. </li></ul><ul><li>What is the most significant force of erosion?
