Bell ActivityDefine “fracture” and “fault” in your study

guide. Find the word on your study guide and complete the following

information for the word.Find the definition using a glossary.Use your own knowledge and experience to complete the rest of the

definition.

Then work on your dinosaur reading from yesterday, and answer questions 6-8 on your study guide.

Today we will be learning about…

Social Studies Objective – We will be able to identify anddescribe the natural processes that have shaped Utah.

Behavior Objective – Work Ethic: We will stay on task and complete our work.

Language Objective –

We will be able to use what we learn to write an outline for an essay.

Our Environment has been shaped & continues to be shaped

by natural forces.

Page 12: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Mountain Building

How were the mountains we see here in Logan created?– They began to be

created in the late Mesozoic era and early part of the Cenozoic era.

– Plate movements have created forces that changed the land and created mountains.

Page 13: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Plates moving together

The Atlantic and Pacific plates are in continual movement.

When they push together they can create mountains.

Other plates around the world do this too.

Page 14: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Mountain Ranges in Utah

Many of our mountains are new, in geologic time.

The Uinta’s are much older. – Do you notice anything

unusual about the Uinta’s when you compare them to the other ranges in Utah?

The Rocky Mountains are unusual. They were not created in the typical way.

Faults shape the earth

Where plates create stress in the Earth’s surface, the crust can break.

Faults are fractures in the Earth’s surface.– They are often where

there are mountains.

Page 18: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

There are three basic types of faults.

Three types of Faults animation

Strike-slip faults

Normal faults

Reverse faults

Page 19: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Logan is also located near a fault

Cache Valley is a special kind of valley/basin created by a normal fault. This special landform is called a graben.

Grabens & Horsts

Page 20: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Utah’s Faults

90% of Utah’s population live on a fault line.

Earthquakes occur where there are fault lines.

Earthquake safety is an important thing to talk about at school and at home.

Page 21: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Did you know that Utah has all three types of volcanoes?

Three Main Types of Volcanoes*

The three main types of volcanoes differ in shape, size, and make-up; the differences partly result from the different types of eruptions.

Volcano Type

Volcano Shape Volcano

Size Volcano Materials

Eruption Type

Utah Example

Cinder Cone Steep conical hill with straight

sides

Small less than

300m high cinders Explosive

Diamond Cinder Cone,

Washington County

Shield Volcano

Very gentle slopes; convex

upward (shaped like a warrior’s shield)

Large over 10s of kms across

fluid lava flows (basalt)

Quiet Cedar Hill,

Box Elder County

Stratovolcano Gentle lower slopes, but steep upper slopes; concave upward

Large 1-10 km in diameter

numerous layers of lava and

pyroclastics Explosive

Mount Belknap, Tushar

Mountains, Paiute County

Page 22: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Utah’s volcanoes are so old they are hard to see.

Shield Volcano - Cedar Hill, located north of Great Salt Lake, bears a resemblance to several Haw aiian shield volcanoes. The

volcano is approximately 1,150,000 years old.

Cinder Cone - Diamond Cinder Cone is one o f several cinde r cones near St. George in Washin gton County, Utah. The cone is

approximately 27,000 years old.

The Tushar Mountains in Central Utah are stratovolcanoes.

Page 23: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Volcanoes in Utah

Volcanoes have played a role in Utah’s past. They also influence our economics in Utah.

Volcanoes bring minerals to the surface of the earth that can be mined.

Page 24: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Some types of natural resources are brought to the surface by these forces.

Gems stones are formed deep beneath the earth. They are brought to the surface through volcanic activity.

Other minerals are also brought to the surface in this way.– This is why Kennecott

Mine, in the Oquirrh Mountains, has copper.

Wearing away the mountains

Utah has also been shaped by other forces, such as wind, water, & ice.

These forces create weathering and erosion that reshape mountains, valleys, and our environment.

Page 28: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Other types of minerals were created by other natural forces.

Coal Oil Shale (Fossil fuel clip) Salt Building stones (marble, granite, quartz, etc.) Gravel & sand (left behind by Lake Bonneville)

Page 29: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

What do you think?

What are some of the environmental issues associated with mining and refining of minerals?

What are some ways these problems can be solved?

What if the problem can’t be solved easily or cheaply? What then should people do?

Page 30: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Utah is an environment shaped by many natural forces.

Page 31: Chapter 2: Utah’s Geology Natural Forces Shape the Land of Utah.

Essay practice: Let’s use what we have just learned to create an essay outline.

How do natural forces shape our environment?

Then close your paragraph by restating your main idea.
