Transcript

  • 1. Group : 1 Presentation : Weathering Presenting member’s: Sadam Hussain Khadam Hussain Ghulam Qader Inam Ghus
  • 2. weathering
  • 3.  Physical [mechanical] Weathering  Chemical Weathering
  • 4. Physical Weathering “Process by which rocks are broken down into smaller pieces by external conditions and no changes in chemical composition ’’. Types of Physical weathering •Frost heaving and Frost wedging •Plant roots •Friction and impact •Burrowing of animals •Temperature changes
  • 5. Chemical Weathering “the processes of chemical weathering transform rocks and minerals exposed to water and air and produce new chemical product. The most common chemical weathering processes are •oxidation, • reduction, •carbonation, and solution.
  • 6. Is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow, and then transported and deposited in other locations. •Transportation, the movement of eroded particles by agents . such as •Rivers, wave ,glacer’s,wind.
  • 7. There are diferente types of erosion:  Wind erosion,  Water erosion, Gravitational erosion, Coastal erosion
  • 8. Difference b/w weathering and erosión . Weathering, is the breakdown of rocks and minerals in earth crust into sediments. Erosion , Weathered rocks and minerals are carried away by Gravity , water , wind and ice called erosion.
  • 9. Weathering and earth system • Atmosphere gases •Hydrosphere (CO2, O2, N) water,moisture,snow •Biosphere Plant , animals after die ,bacteria, bulldozer/ cars , grazing
