  1. 2nd 9 Weeks Science Review Created and modified 1/3/2012 By: C. Horejsi

  2. WIND EROSION ICE EROSION WATER EROSION

  3. ICE Wind WATER weathering

  4. EARTH'S ROTATION Causes NIGHT & DAY

  5. CONSTRUCTIVE & DESTRUCTIVE FORCES

  6. erosion moves soil

  7. breaking down of rocks Water &GRAVITY

  8. The glacier moves down the valley and causes erosion and wearing away of the rock and soil underneath the ice. U = GLACIER

  9. Destructive – wearing away Constructive – build up of sand Destructive – wearing away Destructive – wearing away

  10. Resources in Review What are resources? Resources are things people use. Can you name some resources: wind, water, soil, trees, animals, oil, fossil fuels, solar energy, minerals, rocks, food, electricity, plastic, and many other items.

  11. The most abundant natural resource on Earth 97% is NaCl H20 Can you restate this claim?

  12. Renewable, Nonrenewable, or Inexhaustible Classify the following:

  13. Fossil Fuels F F Non-renewable resources – it takes millions of years to make

  14. Types of Fossil Fuels COP-NG Natural Gas Coal Oil Petroleum

  15. EOPLE, PLANTS RENEWABLE NIMALS ITROGEN PANDAS RINKING WATER IR (ATMOSPHERE) OXYGEN – CARBON-DIOXIDE OIL

  16. Soil Types Loam is a mixture of Clay, Silt, & Sand Sedimentary Layers Clay- tiny particles, retains moisture Silt-fine, rich ingredients, moved from some other place Sand-grainy, mixture Potting Soil – Large particles

  17. Sedimentary Rock LayersWhich layer is the oldest?

  18. Earth’s Resources S.H.E.L Fossil Fuels S.O.W. & Minerals

  22. EOPLE, PLANTS RENEWABLE NIMALS ITROGEN RESOURCES PANDAS RINKING WATER IR (ATMOSPHERE) OXYGEN – CARBON-DIOXIDE OIL

  23. Fossil Fuels F F Non-renewable resources – take millions of years to make. Made from the remains of living organisms – such as plants and animals.

  24. NON-RENEWABLE RESOURCES Fossil Fuels, Rocks, Minerals Takes millions of years to make – cannot be replaced in our life time.

  25. Types of Fossil Fuels COP-NG Natural Gas Coal Oil Petroleum

  26. V U m ountains W eather From Water, Wind, & Ice

  27. MAGNETS have 2 poles Opposites Attract Likes Repel

  28. Electric currents flows through conductors flows through closed circuits
