Praxis II: Geography

Geography
Geography
study of the earth and its physical characteristics, distribution of life on the planet, and how different forms of life interact
4 major elements of the study of geography
1. locations
2. regional characteristics
3. spatial relations
4. natural and man made elements that change the earth
physical geography

cultural geography
study of how the various aspects of physical geography affect individual cultures
-compares different cultures, how their lifestyles and customs are affected by their location, climate, and other factors
Four divisions of geographical study/tools:

Strabo
17 volume description of the ancient world called Geographica
Ptolemy
mapmaker who contributed knowledge to the earth’s geography
How do geographers study distribution of populations and cities?
1. mapping out locations of airports, cities and hospitals, and how they at distributed in relation to habituation
megalopolis
cities that merge into one another
cartographer
mapmaker
What do mapmakers do?
detailed illustrations of geographic areas to record where features are located in that area
Distortion
map does not represent proportions because the round earth is placed on a flat surface
map projection
accurately represents earth’s features on a flat surface
3 types of projection
1. cylindrical projection
2. conical projection
3. flat-plane projection
cylindrical projection
wrapping the globe around a cylindrical paper and using light
-distortion at outermost edges

the way physical features of the earth affect living creatures
3 levels of the environment
1. ecosystem
2. biomes
3. habitat
ecosystem
the environment and all the organisms that live there
biomes
group of ecosystems, using large area of similar flora, fauna, and climate and soil e.g. taigas, deserts, rainforests
habitat
an area in which a specific species lives
-includes the necessary soil, water, and resources for that particular species and others that compete for the same resources
3 categories of interactions with species
1. competition: diff animals of same or diff species compete for same resources
2. predation: one species depends on another for food
3. symbiosis: two different species exist in the environment without affecting one another, some are beneficial to one or both
3 ways a creature can adapt
