GEOG106 lecture 1 notes (2/9/17)
Land surface processes
oNatural color composite satellite image of earth
---this is true color satellite image
what might explain the diffs in color of land area?
Green=vegetation
Tan/yellow=deserts/ barren ground
White=clouds
Blue=water bodies
Scale is very important
o
oFalse composite
Red=vegetation
Has central pivot irrigation—clumps
Tannish area is urbanized areas
Beaches are very bright—blue color
Can see depth diffs here
oGeographers use many different types of scales
What is geography? What do geographers do?
oConnecting, integrating, synthesizing perspective that links knowledge from
different disciplines to study of location and distribution of things (tangible and
intangible). Study of places and the relationships between people and their
environment.

Geographer’s are not the only researchers studying Earth and atmosphere -
Geologists, Meteorologists, Hydrologists, and scientists from many other
disciplines study aspects of Earth’s surface and atmosphere.
But only one scholarly discipline – geographycombines, integrates, and
at its best, synthesizes knowledge from all these other fields.
Scholar by the name of Eratosthenes (pronounced eh-ruh-TOS-thuh-
neeze) (ca 275) coined the term geography in 3rd century BCE, geo
meaning Earth, graphia meaning description
oQuestion is not only where things are located, but also why they are positioned
where they are, and how they come to occupy that position.
oWhat is the cause of the variations in the distribution of phenomena we observe to
exist in geographic space?
oWhat are the dynamics that shape the spatial organization of phenomena of
interest?
Example - Distribution of soils
Know something about rocks from which soils derived
Slopes on which soils developed
Climate and vegetation under which developed
Physical geography
oConcentrates on the physical (natural) elements of the landscape, the processes
involved in their development, their distribution, and their basic interrelationships,
as opposed to the cultural or built environment, the domain of human geography.
oSubfields—physical geography has many subfields (shown here)
oExamples of questions physical geographers address:
Why are arid climates found in this corner of US? (AZ)
Rain shadow
What plant forms and plant communities develop in such locales?
Smaller, spikey, grow closer to the ground, succulents
In what ways and why are the landforms and soils so different than those
out our classroom window?
Thin soil layers, low moisture in soil
Physical geographers use scientific method
oScientific approach is based on observation, experimentation, logical reasoning,
skepticism of unsupported conclusions, and the willingness to modify or even
reject long-held ideas when new evidence contradicts them.
