3 During the days of the dinosaurs, Where was Devils Tower?

4 Under water

5 The time of the Dinosaurs was known as what?

6 Cretaceous

7 Itty bitty particles that settle on the ocean floor

8 Sediments

9 After millions of years, these particles can harden into

10 Sedimentary rock

11 Which rocks were deposited first?

12 Older rocks

13 On the plains, which rocks are found close to the surface?

14 Younger rocks

15 Older rocks deposited first with younger rocks deposited last is what Law?

16 The Law of Super position

17 Which layer is the oldest?

18 The Spearfish Formation

19 What happened to Devils Tower about 66 to 44 MYA?

20 Devils tower was no longer under water

21 The Rocky Mountains and the Black Hills began to form. This is known as the

22 Laramide Orogeny

23 As the Black Hills were uplifted, What happened to the rock layers?

24 The rocks were bent and cracked

25 What forced its way up into the cracks in the rocks?

26 Magma

27 What happened to the Magma?

28 The magma cooled and hardened – It took millions of years.

29 Molten rock that cools and hardens is called what type of rock?

40 The rock that makes up Devils Tower is harder

41 Daily Double!!! What other important event happened about 65 mya?

42 The dinosaurs all died.

48 smaller

49 What type of rock is this?

50 Igneous rock

51 Is Devils Tower made of sedimentary rock?

52 Devils Tower is made of IGNEOUS rock

53 Final Jeopardy! Choose the amount you wish to risk…
