N,D,C,A, J, Science Project

  1. 1. Rocks!!! By:Alyssa,Jean,Nalani,Da Yeon, Cristina.
  2. 2. Definition A rock is a naturally formed solid made of one or more minerals.
  3. 3. Pictures of Rocks <ul><li>Metamorphic and sedimentary rocks. </li></ul>
  4. 4. The rock cycle <ul><li>Some people believe that &quot;once a rock, always that rock&quot;.  But that is not always true.  Rocks take different forms at different times.  </li></ul><ul><li>Rocks are hard natural materials of mineral origin. Different kinds of rocks make up the crust of our planet Earth. </li></ul><ul><li>  </li></ul>
  5. 5. Rock Houses <ul><li>Rain eats away rocks under the surface and carries the rocks away. A small opening forms. </li></ul>
  6. 6. How rocks form <ul><li>The three types of rocks form differently </li></ul><ul><li>Melted rock can reach Earth’s surface through a volcano. Then it cools and becomes igneous rock. </li></ul><ul><li>Sedimentary rock by contrast begins with the break of rocks. Wind and water break rock into bits. Then the wind and water carry the bits of rocks and soil away. The bits settle in to layers. After a long time ago. </li></ul>
  7. 7. How do weathering and erosion affect rocks? <ul><li>Weathering is the breaking down of rock on earth’s surface into smaller pieces. </li></ul><ul><li>Erosion is the process of moving small bits of rock called sediment from one place to another. </li></ul>
  1. A particular slide catching your eye?

    Clipping is a handy way to collect important slides you want to go back to later.
