  1. This Amazing Place: Louisiana The Geography of Louisiana Chapter 1 & 2

  2. Location: • Located along the southern gulf coast • Resembles the shape of a boot • Covers about 48,523 square miles (small state) • Size: 31st out of 50 • 3,600 square miles of water (wettest state)

  3. Boundaries: • Natural Boundaries: • 1. The Mississippi River • 2. The Pearl River • 3. The Sabine River • 4. The Gulf of Mexico • Artificial Boundaries: • 1. 33 north latitude (Arkansas and Louisiana border) • 2. 31 north latitude (Mississippi and Louisiana border) • 3. 94 west longitude (Texas and Louisiana border)

  4. Natural Land Regions: • Determined by climate, soil, vegetation, and relief. • Relief is the difference in elevation between the highest and lowest points of an area. • Flat Land = Low relief • Hilly Land = High relief

  5. Coastal Marshes: • Includes the Gulf Coast • Low wet grassland • Vegetation: grasses and other plants

  6. Floodplains: • Low flat valleys (along the rivers) • Includes the swamps, bayous, and lakes • Vegetation: Deciduous trees (cypress, oak, pecan, and magnolia) • Rich, fertile land, which is good for agriculture

  7. Uplands: • Areas of Louisiana with the highest elevation • Driskill Mountain, the highest point in the state, is 535 feet above sea level. • Piney Hills area (northern Louisiana) and the Florida Parishes (north shore) • Vegetation: Deciduous trees and coniferous (evergreen trees)

  8. Mississippi River: Main artery of Louisiana Largest river in the United States

  9. Red River: • Second longest river in Louisiana • Two unique things: 1. High salt content (flows over a salt dome) 2. White water rapids

  10. Atchafalaya River: • Longest distributary (branch of a river that flows away from the main stream) of the Mississippi River • Half of all the nation’s migratory birds migrate to the Atchafalaya. • Basin supplies the world with 23 million pounds of crawfish a year.

  11. Coastal ErosionGoing…Going…Gone?

  12. What is Coastal Erosion? • The loss of costal land • Greatest threat facing Louisiana (losing about 35 square miles a year)

  15. Coastal Erosion Causes: Prevention:

  16. Climate

  17. Weather Vs. Climate Weather Climate Is the long term weather pattern of a region. It is affected by latitude and altitude. • Is temperature, wind, and precipitation.

  18. Louisiana’s Climate: • Humid subtropical – hot summers, mild winters, and abundant precipitation. • Florida Parishes receives more rain than any other area • Northwest Louisiana receives the least

  19. Hurricanes: • Comes from the Indian word Huracan • (Indian God) • Enormous violent storms (start in the moist air over warm waters like the Gulf of Mexico and Atlantic Ocean) • Hurricane Season: June 1st – November 30th.

  20. Saffir-Simpson Scale:

  21. Population: • 2000 Census: 4.5 million people • 2010 Census: 4.6 million people • St. Tammany Parish – fastest growing parish • Things that Impact Population: • 1. Declining Birth Rate • 2. Economics (loss of jobs) • 3. Natural Disasters: Hurricanes Katrina and Rita forced people to evacuate. • 4. High poverty levels and crime rates
