2 5 Themes of Geography Location – every place has a specific location on earth. Place – every place has physical (natural) and cultural (man made) characteristics. Human-Environment Interaction – how humans use and interact with the environment. Movement – the ways we are linked with regions, cultures, and people beyond our immediate environment Regions – Regions are defined as areas with similar characteristics

3 MS In The U.S.

4 Mississippi Geographical Regions
Four Geographical Regions Delta Hills Piney Woods Gulf Coast

5 Mississippi Climate and Weather
MS has a humid subtropical climate. Summers are hot and winters are cool. State is humid and has ample rainfall MS climate & rainfall helped create an agricultural state Avg. Temp. in MS is 62°F Highest Ever 115°F Lowest Ever - 19°F Avg. Precipitation is 52’’ per year 60’’ on the Gulf Coast



8 Natural Hazards of Mississippi
T-Storms are frequent and can result in flooding Lightning is a problem in MS Tornadoes – measured on the Fujita Scale (F1-F5) Hurricanes – measured by the Saffir-Simpson Scale (1-5) Earthquakes – low chance, but NW MS does sit near the New Madrid Fault

9 Fujita Scale Saffir-Simpson Scale

10 Hurricane Katrina

11 The Earth’s Spheres Atmosphere – The Earth’s gases.
Lithosphere – all of the Earth’s land. Hydrosphere – all of the Earth’s water. Biosphere – all of the Earth’s life.
