THE CARTOGRAPHER’S TASK
Scientists collect data: remote sensing/census/
sonar
Cartographers display this data:
1 – globes
2 - maps; inherent distortions
Four components of a MAP:
1- title
2- legend (key)
3- scale 4- direction indicator

THE 5 THEMES OF
GEOGRAPHY
CH 1 SECTION 1 NOTES
THE FIVE THEMES OF
GEOGRAPHY
•
•
•
•
•
Location
Place
Human-Environment Interaction
Movement
Regions
LOCATION
Where are we?
• Absolute
Location
– A latitude and
longitude (global
location) or a street
address (local
location).
– Paris France is 48o
North Latitude and 2o
East Longitude.
– The White House is
located at 1600
Pennsylvania Ave.
• Relative Location
– Described by
landmarks, time,
direction or distance.
From one place to
another.
– Go 1 mile west on
main street and turn
left for 1 block.
PLACE
What is it like there, what kind of place is
it?
• Human
• Physical
Characteristics
Characteristics
• What are the main
languages, customs,
and beliefs.
• How many people live,
work, and visit a place.
• Landforms (mountains,
rivers, etc.), climate,
vegetation, wildlife, soil
HUMAN-ENVIRONMENT
INTERACTION
• How do humans and the environment
affect each other?
– We depend on it.
• People depend on the Tennessee River for water and
transportation.
– We modify it.
• People modify our environment by
heating and cooling buildings for comfort.
– We adapt to it.
• We adapt to the environment by wearing
clothing suitable for summer (shorts) and
winter (coats), rain and shine.
MOVEMENT
• How are people, goods, ideas moved from
place to place?
– Human Movement
• Trucks, Trains, Planes
– Information Movement
• Phones, computer (email), mail
REGIONS
• How are Regions similar to and different from
other places?
– Formal Regions
• Regions defined by governmental or administrative boundaries
(States, Countries, Cities)
• Regions defined by similar characteristics (Corn Belt, Rocky
Mountain region, Chinatown).
– Functional Regions
• Regions defined by a function (newspaper service area, cell
phone coverage area).
– Perceptual Regions
• Regions defined by peoples perception (middle east, the
south, etc.)
Remembering the 5 themes
• If you can’t remembering what
they are just ask MR. HELP!!!
• M – Movement
• R – Regions
• HE – Human Environment
interaction
• L – Location
• P - Place

THE LAYERS OF THE EARTH

key fossils across these landmasses.

Plate tectonics:
Weathering
• Weathering- is breakdown of rock at or
near the earth’s surface into smaller and
smaller pieces.
• Over millions of years, weathering can
reduce a mountain to gravel.
• Two kinds of weathering: Mechanical
weathering, chemical weathering
Glacial moraines:
Mechanical Weathering
• Occurs when rock is actually broken or
weakened physically.
• Breaks large masses of rock into even
smaller pieces, producing boulders,
stones, pebbles, sand, silt, and dust.
• Common mechanical weathering: takes
place when water freezes to ice in a crack
in the rock. Water expands when it freezes
ice widens the crack. Frost wedging.
Mechanical Weathering
• Seeds take root in cracks in rocks,
sidewalks crack when tree roots grow
beneath them.
Chemical Weathering
• Chemical weathering can destroy a rock
• Is the process of chemical weathering
alters a rock’s chemical makeup by
changing the minerals that form the rock
or combining them with new chemical
elements. Change one kind of rock into a
completely different rock.
Chemical Weathering
• Water, carbon dioxide important factors.
• Caves formed with carbon dioxide
• Dry regions there is little chemical
weathering. Wet and damp area chemical
weathering occurs quickly and is
widespread.
• Acid rain- type of chemical weathering,
chemicals in polluted air combine with
water vapor and fall back to earth as acid
rain.
Chemical Weathering
• Acid rain destroys forests and pollutes
water, and eats away at the stone
buildings and natural rock formations.
Erosion
• Is the movement of weathered materials
example: gravel, soil, and sand.
• Three common causes of erosion are
water, wind, and glaciers.
• Sediment-small particles of soil, sand, and
gravel. Sandpaper.

Weather and Climate
• Weather- is the condition of the bottom
layer of the earth’s atmosphere in one
place over a short period of time.
• Atmosphere – is multilayer band of gases,
water vapor, and dust above the earth.
• Weather is an almost constant change,
sometimes shifting from warm to cool and
back again in a short period of time.
Weather and Climate
• Climate- is the term of the weather
patterns that an area typically experiences
over a long period of time.
• Climate of an area depends on a number
of factors:
– Elevation
– Latitude
– Location in relation to nearby landforms and
bodies of water.
Currents
• Waters and oceans help distribute heat
• Following convection patterns similar to
those of winds, ocean currents, both near
the ocean’s surface and far below it.
• Precipitation:
– Humidity is the amount of water vapor
contained in the atmosphere.
– Forms when air temp changes.
Convectional Precipitation
• Hot , humid air rises from the earth’s
surface and cools, thereby losing its ability
to hold much water.
• Common near the Equator and in the
tropics.
• Produces nourishing rainfalls that feed
lush, tropical forests
Orographic Precipitation
• Warm, moist air is forced upward when
passing over high landforms causing
precipitation.
• Common on the seacoasts where moist
ocean winds blow toward coastal
mountains.
• Warm winds cool as they rise up over the
mountains.
Frontal Precipitation
• Common kind of precipitation occurs when
two fronts : air masses of different
temperatures meet.
• Warm air is forced upward by the heavier
cool air. Rising warm air cools and frontal
precipitation forms.
Other Influences on Climate
• Nearby bodies of water:
– Winds blow over water take on the waters
temperature.
– Continental climates:
• Northern Hemisphere have what are known as
continental climates.
• Hold and warm summers and cold, snowy winters
