Missouri Geography

• Missouri Unit

2
Location

• Relative and Absolute Location
• Relative - General description of a location.
• Absolute - Exact Location using latitude and
  longitude
• Latitude lines measuring North and South from the
  Equator.
• Longitude lines measuring East and West from the
  Prime Meridian.

3
5 Themes of Geography

• Location
• Place
• Human and Environment Interaction
• Movement
• Regions

4
Location

• Description of a place using Absolute or Relative
  Location.
• Example your house
• The School
• Describe the location for Relative.
• Give Lat and Long to describe Absolute.

5
Place

• Describe somewhere using Physical or human
  characteristics.
• Physical - naturally occurring ex. Mountains
• Human - man made ex. Roads and bridges.

6
Human and Environment Interaction

• Interaction between humans and their environment.
• Question?
• Do we adapt to our environment or do we adapt our
  environment to us?
• Anyone cold?

7
Movement

• Movement of goods, services, ideas, and people
  throughout the world
• Examples
• Planes, Trains, and Automobiles.
• New Movements?

8
Region

• Areas with similar characteristics.
• Not restricted by their proximity to each other.
• Deserts, Tundra, Plains, etc...

9
Regions of Missouri

• Glaciated Plains
• Osage Plains
• Mississippi Alluvial Plains
• Ozark Plateau

10
Glaciated Plains

• Northern part of Missouri.
• Once covered in glaciers during the Ice Age.
• Melted and left very fertile soil.
• Farming and Agriculture.

11
Osage Plains

• Eastern extension of the Great Plains
• Soil is dryer and rockier.
• Some agriculture, but not nearly as fertile as
  the Glaciated Plains.

12
Mississippi Alluvial Plains

• Bootheel used to be covered in swamps and
  wetlands.
• The state and farmers have built levees and
  canals that allow the water flow to be
  controlled.
• This allows farming of the rich soil.
• Tobacco, rice, and cotton

13
Ozark Plateau

• Old worn down mountains.
• Along with the Appalachian Mountains they are the
  oldest in the country.
• Most of the central and south west portion of the
  state.
• Mt. Taum Sauk in St. Francois County 1772 Ft.

14
Geology

• Most of MO is made up of Igneous Rock - or liquid
  that cooled and was compressed until it formed
  rock.
• Granite and Rhylite
• Much of the rock runs 4000 ft. under the surface.
• Rivers both above and under ground have eroded
  this rock.

15
Caves

• Missouri has over 3000 caves.
• Stalactites - Long icicle like formations forming
  from the top of a cave.
• Stalagmites Long icicle like formations from the
  bottom of a cave.
• Both caused by water dripping and combining with
  minerals.

21
New Madrid Earthquake

• December 1811
• The New Madrid Fault awakened and began a series
  of earthquakes and tremors that lasted 3 Monts
• Felt in Boston, MA and Toronto, Ontario, CN.

22
Earthquake

• Plates rub along each other creating ground
  movements.
• The Mississippi River ran BACKWARDS for a time
  after the earthquake.
• The water level raised 12 ft in minutes.
• Huge waves destroyed whole town like
  Caruthersville, MO
• No Deaths!

23
Climate

• Average weather over a measured period of time.
• Continental Humid - The weather is variable based
  on the seasons.
• Transitions
• Winter - Cold/Wet Snowfall
• Winter - Cold/Dry
• Summer - Hot/Dry
• Summer - Hot/Wet

24
Borders

• Both natural and manmade borders.
• Major natural borders
• MO River
• MS River
• St. Francois River

25
Borders

• Natural
• 4030 N
• 36 N Bootheel
• 36 30 S

26
Waterways

• Aquifer - Underground H20 system filters through
  rock and soil used for manmade wells
• Pollution - Runoff from fertilizers can pollute
  the aquifers
• Rivers - 11,000 miles of streams and rivers
• Borders
• What else can rivers be used for.

27
Water...

• Lakes
