Understanding Weathering and Erosion Processes

Explore the various types of weathering and erosion, from physical processes like root pry and frost action to chemical breakdown such as oxidation and acid rain. Learn how these natural forces shape the Earth's surface over time.

  1. Weathering And Erosion Weathering And Erosion

  2. The Different Types of Weathering Weathering Physical and Chemical breakdown of rock Physical - Root Pry -Exfoliation -Frost Action -Wind Abrasion • Chemical • - Oxidation • - Acid Rain

  3. Why is this rock red? OXIDATION

  4. Root Pry What will happen to the rock the tree is growing in. The rock breaks apart

  5. Exfoliation Peeling away of rock. This makes the half dome.

  6. Frost Action or ice wedging slowly breaks up this sedimentary rock into unusual shapes.

  7. What could have caused these rocks to become rounded. WIND ABRASION

  8. 1908 to 1969 What could have eaten away this statue? Acid Rain

  9. Erosion Process of wearing away the earth’s surface. Types of erosion: • Wave Action • Running Water • Landslides • Creep • Rock Fall • Mud Flow • Avalanche • Glaciers • Slump

  10. Wave action - when waves hit the rocks and pieces of rock break off.

  11. Running water eroded the sides of this canyon and created the V-shaped valleys.

  12. Mass Wasting - landslides

  13. A slump is when a clump of earth breaks apart and falls

  14. Creep. Land slowly slipping over many years from temperature or water.

  15. This avalanche is an example of Mass Wasting

  16. This glacier carves out a U-shaped valley by dragging rocks and boulders with it

  17. Deposition • When erosion stops and particles that were moving are settled in a new location.
