Presentation Transcript

  1. Warm-up Week 3 Day 3 • Describe lines of Longitude and Latitude in your own words. • Which kind of map has contour lines? • What is constant at any point along a contour line? • How does advanced mapping technology help Earth Scientists?

  2. Earth System Science Chapter 1, Section 4

  3. Earth = “Dynamic” planet Many separate but interacting parts Spheres Earth Scientists: Study how separate parts affect each other. Chemistry, Biology, Physics, Math, etc…

  4. The Earth System

  5. Systems? • Group of interacting parts that form a complex whole. • Ex: Solar system • Natural systems work because of Energy. • Ex: Sun  Heat  Movement • “Open Systems” • Energy & Matterenters/leaves system. • Ex: River.

  6. Change one part = changes other parts. Human actions create changes in all other parts of the Earth system Gasoline use Trash Farming Sea walls

  7. Sources of Energy. • Sun! “Powers” processes in: • Atmosphere(Weather/Climate) • Hydrosphere(Ocean Currents) • Earth’s Surface(Erosion) • Earth’s Interior! • “Ancient heat” • Radioactive decay  makes heat “Powers”: • Internal Processes Mountain making, volcanoes.

  8. “Environment” Everything that surrounds & influences an organism. • Biological • Social • Non-living • Temperature • Humidity • Sunlight

  9. “Environmental Science” • Study, Relationship… Humans & Natural Environment.

  10. “Resources” Necessary items. • Renewable: • Replenish quickly • Non-renewable: • Replenish VERY slowly. • Limited!

  11. Human PopulationGrowth

  12. Problem. ↑ Human Population =↑ Demand for Energy Resources. We Must find a way to meet the ↑ demand for non-renewable resources. We change. Or, we all die.

  13. Reflection • List 3 activities that you do in a typical day. • Below each activity write 1 renewable resource and 1 non-renewable resource that you use in this activity. • Think. • List an alternative resource for each non-renewable resource that you use each day. • Is your consumption absolutely NECESSARY? • Write a paragraph explaining how you might change your habits.

  14. Assignment • Read Chapter 1, Section 4 (pg.18-22) • Do Section 1.4 Assessment #1-8 (pg. 22)
