1. Geology Review Game Ready your Mind!

2. Your teams are your table groups

3. 2.) Which Layer of Rock is the OLDEST? 1.A 2.B 3.C 4.D 5.E 6.F 7.G

4. 3.) Which Layer of Rock is the YOUNGEST? 1.A 2.B 3.C 4.D 5.E 6.F 7.G

5. 4.) Which Layer of Rock is the third youngest? 1.A 2.B 3.C 4.D 5.E 6.F 7.G

6. 5.) Why are index fossils useful to geologists? 1.They tell the absolute of the rock. 2.They tell the ages of MANY rock layers in different locations 3.They tell how the fossil was formed. 4.They tell the EXACT age of the entire rock layer.

7. 6.) Which is the correct sequence of events? (oldest first) 1.H, M, R 2.M, B, R 3.I, H, M 4.I, M, H 5.R, F, B

8. 7.) What is meant by the relative age of a Strata? 1.Its age compared to other rocks or fossils. 2.The number of years since it formed. 3.Its age as determined by carbon dating. 4.Its age as determined by the radioisotopes it contains.

9. Rock “E” would be an example of what cross-cut? 1.Fault 2.Fold 3.Intrusion 4.Extrusion 5.Unconformity

10. Determining whether an object is older or younger than other objects is called what? 1.Relative dating 2.Absolute dating 3.Radiometric dating 4.Gradualism

11. Which of the following is a crosscutting relationship? 1.fold 2.fault 3.extrusion 4.All of the above

12. Which law states this, as sedimentary rocks form, they are deposited on older rock layers. 1.Law of Superposition 2.Law of Horizontality 3.Uniformintarianism 4.Law of Cross-Cutting Relations

13. What is an extrusion? 1.A break in the rock 2.Layers of rocks bend or curve 3.When magma pushes through rock layers 4.When lava reaches the surface.

14. This law states that layers of sediment were originally deposited horizontally under the action of gravity. 1.Uniformitarianism 2.Superposition 3.Horizontality 4.Cross-Cutting Relations

15. Are intrusions, extrusion, faults, and folds younger or older than the rocks that they invade? 1.Younger 2.Older

16. What must occur for an unconformity to form? 1.Fault 2.Fold 3.Erosion 4.Igneous rock

17. Write a Geologic History for this picture. Name all the cross-cutting relationships and any Unconformities.

18. Cross Cuts- C Intrusion, G is a Fault Unconformities- Nonconformities between lines D and C, F and C Disconformities between lines D and H, H and A Angular Unconformities between lines F and E, I and E, and B and E unconformity at the top of E 1 Sedimentary layer of D was created. 1 Sedimentary layer of H was created 1 Sedimentary layer of A was created Layers D, H, and A are compressed and bent to form folds. An intrusion C cuts through layers D,H and A but not to the surface. A fault G cuts through layers D, H, A and the Intrusion C. 1 Sedimentary Layer F was created 1 Sedimentary layer I was created 1 Sedimentary layer B was created Layers F, I, B are uplifted and titled. 1 Sedimentary layer of E was created.
