Take out all the work you have for this class. Work on them in this order:1) Turn in the tan paper to your cubby.2) Fill out the map on page 7 of your study guide.3) Fill out the counties map using page 194 for

help.4) Work on your essay. We will go over this 15

minutes before the end of class.5) Work on any incomplete parts of the study

guide, including vocabulary entries and questions.Last) I will answer 5 questions from the study

guide the last 5 minutes of class. Where should your backpack be?

History Objective – We will prepare fortomorrow’s exam byreviewing the studyguide.

Behavior Objective – Participation & Work Ethic: We will listen to each questions, answer the ones given to us, and write the important details in our notes.

Language Objective – We will listen to, give answers and write the important details from the activity.

Today we will learn…

25.Describe 5 ways natural forces (disasters) have changed the land during the last 50 years.

1) Floods recently broke a dam in S. Utah causing mud to fill a neighborhood 2) Fires left land in the SL area without plants to hold the soil in place when it rains, causing homes to be flooded with mud. 3) Drought and high temperatures caused a lot of fires this year  4) Earthquakes have displaced land and caused building to collapse 5) Avalanches carry debris across the land each winter.

26. Utah has many small _________________________ every year.

earthquakes

27. What are some ways to stay safe in a natural disaster?

-Learn about the disasters that can happen in your area.-Make a plan and get supplies that can help you stay alive during a disaster.-Practice what to do in an emergency.

1)2)3)

19.Name and describe Utah’s Ice Age lake.

1) Lake Bonneville covered 1/3 of Utah, and was a fresh water lake. It disappeared after a flood and the climate changed.

20. Which of today’s lakes are the remnants of that lake? (3)

1) Great Salt Lake 2) Utah Lake3) Sevier Lake

21. What huge Ice Age animal bones were found at the Huntington Reservoir

The remains of a mammoth was found there.

22. Name 5 other Ice Age animals that once roamed Utah, but that are now extinct.

1) Musk ox2) Smilodon (sabertooth cat)3) Mastadons4) Giant Sloth5) Camels

24) Name two paleontologists who have worked in Utah?

1) David Gillette

2) Earl Douglass

3) James Kirkland

23) What does a paleontologist study? What can we learn about the past from their work?

Paleontologists study ancient life forms that are preserved in fossils.

We can learn what the earth was like (climate, plants, animals, etc.) in ancient times from their work.

16. Much of Utah’s electricity is produced by burning ___________ to produce steam.

coal

17. What is Utah’s salt used for primarily?

It is used to melt snow in the winter and for water softeners. Some is used for seasoning food.

18. Name 5 other important natural resources in Utah’s economy.

Answers will vary:1) copper2) silver3) potash4) oil shale5) berillium

9. Name 5 natural forces and explain how they shape Utah.

1) Uplift forms mountains and plateaus.2) Water erosion carves canyons.3) Wind erosion creates arches and caves.4) Mud flows move sediments to new areas.5) Deposition leaves layers of sediment in the bottom of rivers, lakes, oceans, etc.

10. How were the Rocky Mountains formed? (pictures with descriptions would be perfect)

Uplift from the pacific plate shallowly crashing into the North American plate caused the crust to buckle, creating the new mountain range.

11. What is a fault, and what happens when land slips along a fault?

A fault is a fracture in the earth’s crust that can cause earthquakes when it moves.

13. Magma that pushes up through the Earth’s crust forms ____________________ rock.

Igneous

14. Sediments that accumulate and cement form _____________ rock.

sedimentary

15. Heat & pressure under the Earth’s surface changes Igneous & Sedimentary rock into _________________.

metamorphic

6. Retell the main events of the discovery of Utah’s first dinosaur bones near Vernal.

1) Earl Douglas2) Finds dinosaur bones in the

Vernal area in early 1900s3) Sends the bones to museums

like the Carnegie, Smithsonian, and University of Utah Natural History museum.

7. Why are Tyrannosaurus Rex bones rarely found in Utah?

The layers of sediment that they would have been found in have eroded away over millions of years. Most rocks in Utah are from the Paleozoic Era or Jurassic Period, not the Cretaceous Period when Trex lived.

8. Where are most new dinosaurs being discovered in Utah today?

Southern Utah near the Grand Staircase Escalante National Monument

1. How do geologists learn the history of the land?

They study the rocks, layers of sediments, and other geological features of an area to learn what that place was like in the past.

2. Describe the sources of Utah’s igneous rock, sandstone, and limestone in Utah.

Igneus rock comes from volcanic activity, sandstone is the remains of ancient sand dunes or beaches, and limestone is formed at the bottom of ancient lakes, seas, and oceans.

3. How are fossils formed? (pictures help)

4. What is one of the oldest animal fossils you can find in Utah?

Trilobites are some of the oldest fossils you can find in Utah.

5. Utah’s land was once completely covered with ________________.

Shallow seas
