Geography |
The science of PLACE in relation to SPACE and TIME |
|
|
Five themes |
•Location - relative + absolute •Place - human + physical •Movement - how biomes shift/migration •Regions - biomes based on region •Human - environment interaction |
|
|
Biomes |
Largest recognizable subdivision off terrestrial ecosystems |
|
|
Biomes classifications |
Flora Fauna Flora-Flauna interactions Vegetation structure Adaptations to environment |
|
|
Biomes |
•Ice sheet/polar desert •Tundra •Taiga/Boreal Forest •Montane (Alpine) •Deciduous forest •Tropical rainforest •Steppe •Desert •Mediterranean •Savanna |
|
|
Types of climates |
Tropical Dry arid/semi arid Mesothermal Microthermal Polar Highland |

|
Absolute location vs. relative |
Absolute - definite longitude/latitude Relative - in relation to something |
