Transcript

  • 1. Earth movements(endogenetic forces)By Mandeep Kaur Sandhu
  • 2. • Geological changes can be long time or short time.
  • 3. Epeirogenic diastrophicEndogenic Orogenic forces sudden
  • 4. • Sudden forces
  • 5. • Diastrophic forces (slow forces) – Epeirogenetic (continent origin) – Orogenic (mountain forming) epeirogenetic orogenic Tensional Upward (crustal (emergence) Fracture) Compressional Downward (crustal (submrgence) Bending)
  • 6. • Upward forces – Upliftment of continents – Upliftment of coastal land
  • 7. • Downward movements – Submergence of land area (subsidence) – Submergence of land near coast(submergence)
  • 8. • Orogenic forces are horizontal in nature either – opposite to each other (tensional or divergent forces)
  • 9. • towards same direction (compressional or convergent ). • Crustal folding • Crustal warping
  • 10. • Folds – Wave like bends – Due to tangential compressive forces – Anticlines and Synclines
  • 11. • Types of Folds – Symmetrical folds – Due to regular and moderate forces
  • 12. • Asymmetrical folds
  • 13. • Monoclinal folds – More possible to cause faults at intense pressure of the horizontal forces.
  • 14. • Isoclinal folds
  • 15. • Recumbent folds
  • 16. • Overturned folds
  • 17. • Plunge folds
  • 18. • Fan folds – Anticlorium and synclorium
  • 19. • Faults – Crustal rocks are displaced – Due to tensional forces
  • 20. • Types of Faults – Normal faults – Reverse faults – Lateral faults or strike faults – Step faults
  • 21. Thanks …
