Missouri Geography Missouri Unit 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. 5 Themes of Geography • • • • • Location Place Human and Environment Interaction Movement Regions 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. Place • Describe somewhere using Physical or human characteristics. • Physical - naturally occurring ex. Mountains • Human - man made ex. Roads and bridges. 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? Movement • Movement of goods, services, ideas, and people throughout the world • Examples… • Planes, Trains, and Automobiles. • New Movements? Region • Areas with similar characteristics. • Not restricted by their proximity to each other. • Deserts, Tundra, Plains, etc... Regions of Missouri • • • • Glaciated Plains Osage Plains Mississippi Alluvial Plains Ozark Plateau Glaciated Plains • • • • Northern part of Missouri. Once covered in glaciers during the Ice Age. Melted and left very fertile soil. Farming and Agriculture. Osage Plains • Eastern extension of the Great Plains • Soil is dryer and rockier. • Some agriculture, but not nearly as fertile as the Glaciated Plains. 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 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. 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. 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. Plotting Latitude and Longitude • All Latitude and Longitude are measured in Degrees - Minutes - Seconds • 60 Seconds = 1 Minute • 60 Minutes = 1 Degree • Max of 180 Degrees E,W,N, &S Convert • 90º 71’ 80” W • 91º 12’ 20” W • 120 º 119’ 61” • 122 º 1” Plot • 39 degrees North 76 degrees West. • Washington DC • 33 degrees North, 117 Degrees West • San Diego New Madrid Earthquake • December 1811 • The New Madrid Fault awakened and began a series of earthquakes and tremors that lasted 3 Months • Felt in Boston, MA and Toronto, Ontario, CN. 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! 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 Borders • MO covers 70,000 sq. miles. • Both natural and manmade borders. • Major natural borders – MO River – MS River – St. Francois River Borders • Manmade – 40°30” N – 36° N – 36° 30” N Bootheel 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. Water... • • • • • • Lakes MO does not have any natural large lakes. Created by damming rivers. Taneycomo Bull Shoals Smithville L of O Table Rock Mark Twain
