  1. Calving Glacier http://www.youtube.com/embed/hC3VTgIPoGU?rel=0

  2. Aim --> Sequence of Events

  3. Uniformitarianism - processes that occur today have always occurred. "The present is the key to the past." Examples include weathering, erosion, earthquakes etc.

  4. Law of Superposition - oldest rocks are on bottom. exceptions - extensive folding, thrust faulting, igneous intrusions

  5. Law of Original Horizontality - Sedimentary rocks are deposited underwater in horizontal layers. THEY CAN OVERTURN AND CRACK. How?

  6. Igneous intrusion - magma rises up/squeezes between rock layers below ground. Causes contact metamorphism in older layers.

  7. Cross Cutting Relationships - any formation which crosses another is younger than the formations itcrosses. Examples; Folds, Faults, Intrusions, Extrusions, Unconformities

  8. Faulting

  9. Folding

  10. Folding

  11. Tilting

  12. B A C D

  13. Layers are formed according to superposition.

  14. Faulting

  15. Something happens to uplift the area: folding faulting, etc.

  16. Erosion wears away the uppermost layers

  17. Area submerges and deposition begins again.

  18. What came first the rock or the pieces of rock that the rock is made up of?

  19. Law of Inclusion - the sediments which make up a rock are older than the rock

  20. List the sequence of events

  21. Describe the sequence of events for the above diagram

  22. Sequence of Events Lab • You must tell when Unconformity (buried erosional surface happens), Folding, Faulting, Tilting, Igneous Intrusions…..
