Powerpoint pres part 1

  1. 1. Earth ScienceSecond Grade<br />Ariel Kaiserman<br />
  2. 2. Landforms<br />Mountains<br />Plains<br />Plateaus<br />Valleys<br />Hills<br />
  3. 3. Mountains<br /><ul><li>Tall, rough, pointy
  4. 4. Rocky mountains and Appalachian mountains
  5. 5. Animals: vultures, llamas, mountain goats</li></li></ul><li>Plains<br />Plains: vast, flat, no great changes<br />Uses: growing crops, raising animals<br />Animals: buffalo, prairie dogs, coyotes<br />
  6. 6. Plateaus<br />Elevated level land surrounded by steep slopes<br />About 45% of Earth’s surface<br />Low: farming, high: livestock grazing<br />
  7. 7. Valleys<br />Surface depressions bounded by mountains or hills<br />Naturally slopes downward to lakes, streams, ocean<br />V-shaped: river erosion<br />U-shaped: Ice berg<br />
  8. 8. Hills<br />Rounded slopes, “baby mountains”<br />Spread out in all other landforms<br />Caused by surface movement, deep erosion<br />
  9. 9. Slow Surface Changes<br />Natural, slowly and gradually (over time)<br />Erosion<br />Surface materials changed by Wind/Water/Animals<br />No large difference in appearance<br />
  10. 10. Rapid Surface Changes<br />All at once, not gradual<br />Landslides, Volcanic Eruptions, and Earthquakes<br />Major difference in appearance<br />Forms new land, mountains, valleys<br />
  11. 11. Landslides<br />Mountains / Hills<br />Starts at top and grows<br />Soil moisture, angle of slope, construction<br />Landslide Example<br />
  12. 12. Volcanic Eruptions<br />Many kinds of volcanoes (composite, shield, caldera)<br />Opening in Earth’s crust, magma comes through<br />“Paint drawing”<br />Hawaiian Islands<br />Volcanic Eruption in Hawaii<br />
  13. 13. Earthquakes<br />Caused by sudden movement of Earth’s crust<br />Measured with a Seismometer (3-small, 7-serious damage)<br />Earthquake description<br />
  14. 14. Water Sources: Wells<br />Structure drilled/dug under ground<br />Comes from an aquifer (layer of water)<br />
  15. 15. Springs<br />Groundwater flows out of cracks in Earth’s surface<br />Amount: size of area and human interaction<br />Usually clear, sometimes colored by iron deposits<br />
  16. 16. Lakes<br />Freshwater surrounded by land<br />Deeper than a pond, not part of the Ocean<br />Great Lakes of Michigan<br />
  17. 17. Rivers<br />Narrow, freshwater, always flowing<br />Flows toward lakes, oceans, or seas<br />Longest river: The Nile (4,135 Mi)<br />
  18. 18. Oceans<br />All salt water<br />70% of Earth’s surface<br />Four main: Pacific, Atlantic, Indian, Arctic<br />
