Understanding Erosion and Earth's Resources: A Comprehensive Overview

This review explores the concepts of erosion caused by wind, ice, and water, emphasizing the roles of constructive and destructive forces in shaping the Earth's landscape. It discusses the types of erosion, the movement of glaciers, and the breakdown of rocks and soil. Additionally, the document covers vital natural resources, categorizing them into renewable, nonrenewable, and inexhaustible types. Key resources such as fossil fuels, minerals, and water are examined, alongside their significance and classification in our ecosystem.

  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
