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.
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 Lake
3) 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 ox
2) Smilodon (sabertooth cat)
3) Mastadons
4) Giant Sloth
5) 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) copper
2) silver
3) potash
4) oil shale
5) 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 Douglas
2) Finds dinosaur bones in the Vernal area
in early 1900s
3) 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.

(pictures help)
