Vocab intro Flashcards
Population density
Population per unit area
Region
An area on the Earth’s surface marked by specific criteria (area, boundaries, location, homogeniety) -physical or cultural. (all have area, boundaries, & location)
Characteristics of a Region
Area
Boundaries
Location
Homogeniety
Formal Region
Marked by a certain degree of homogenity in 1+ phenomena (physical or internal) immobilistic
aka: uniform/homogeneous region
Functional Region
spatial system marked by dynamic internal structure (urban core/economic activity)
aka nodal region
two types of things that can mark a functional region
urban core
economic activity
Physical Geography
Wegner’s theory of Pangaea based on tectonic/lisopheric plates
Tectonic Plates
heavy rocks moving propelled by giant circulation cells in the red ot magma below & carry continents
Volcanoes & earthquakes result when they collide
aka lisopheric plates
Subduction
When oceanic plate converges head on with a plate carrying a continental landmass @ its leading edge. The light plate overrides the plate & pushes it downward
Ring of Fire
Pacific Ocean almost completely encircles by active volcanoes & earthquake epicenters
Climate
aggregate, total recodrd of weather conditions at a place, or in a region, over the entire period during which records have been kept
Impacts how, where, & why ppl live where they are living
Physiological density
Population per unit area of arable land
arable
can be used for agriculture and habitation
Development
the economic, social, and institutional growth of national states to improve the well-being of its people
Geo
Earth
Graphos
to write/describe
Spatial viewpoint
how, why, and where things are located on the earth’s surface the way they are
Transition Zone
area of spatial change where peripheries of two adjacent regions join, makred by a gradual shift in the characteristics that distinguish neighboring realsm
ex: subsaharan africa & north africa/southwest asia
Scale
ratio of distance on a map to ground distance
Cultural landscape
the composite of human imprints on the earth’s surface- always being modified & evolving
Culture
Shared patterns of learned behavior (not part of DNA)
“A” climate
tropical conditions, high temps, never freezes, all year around precipitation (may be wet, dry, wet, or wet monsoon)
“B” climate
low & high altitiudes (found anywhere)
“Bw” climate
true desert (<10 cm rain annually)
“Bs” climate
semiarid >10 cm rain annually
“D” climate
only found in northern hemisphere (only category found in 1 hemisphere), continental climate, no equivalent land areas in Southern Hemisphere, cold winters, cool summers, best soil here (not necessarily most productive)
“C” climate
Mid-latitudes beyond tropics, no climate extremes, cold winters, precipitations range from moist-dry summer
“E & H” Climate
frigid conditions with many places with permanent ice & snow
“E” climate
near poles
“H” climate
at equator or low latitudes, but at high elevation (arctic like conditions then)
Spatial scient
arrangement of everything on the earth’s surface (what geography is)
geographic realms are based on
spatial criteria
the largest geographic units into which the inhabited world can be divided
geographic realms
what is based on physical and human yardsticks
geographic realms
geographic realms resulted from
interaction between human societies & natural environments
