AH9 – Outline #1 – Chapter 1
Wherever people live, they have shaped their environment to suit
their needs. The Human ability to change the environment, however,
is limited. Often, people must adapt their agriculture, industry,
arts, and daily habits to their surroundings. It is important to see
the connections between people and their environment.
I. The Global Environment
A. Geography =
Study of people, their environments and their sources
How the natural environment affects the way we live and how we affect the environment
B. The 5 Themes of Geography
1. Location = Where did it
happen? To answer this we turn to relative and exact location.
a. Relative Location =
the location of a place in relation to another
can help explain why people settled in certain areas or why battles took place
in certain areas
b. Exact (absolute) Location =
use of grid numbered lines on a map or globe
c. Latitude =
measure North and South from the Equator
+ Equator =
imaginary line at 0 degrees latitude, divides the Earth into two
halves called hemispheres
middle from the two poles
d. Longitude =
measures distance East and West of the Prime Meridian
+ Prime Meridian =
runs through Greenwich, England
Zero degrees
middle of nothing
2. Place = Geographers describe places in terms of their physical and
human characteristics.
Physical Features =
include climate, soil, vegetation, animal life, and bodies of water
natural resources (or materials that humans can use from the
environment)
Human Features =
kinds of houses, means of transportation, ways of earning a living, languages, and religions
3. Interaction between People and their environment = wherever people live, they change the world
around them. They may clear forests, blast tunnels through
mountains, or plow fields.
How did the Native Americans
adapt =
learned to plant seeds and grow food, not having to be nomadic
Irrigation or bringing of food into dry lands with American southwest
natives.
Arid lands into productive lands
b. Today’s Adaptations =
Advanced technology changes the environment dramatically
wiped out pests
take oil from the ocean floor
4. Movement = the fourth theme is Movement, the movement of
people, goods, and ideas.
a. Why does movement occur? =
because people and resources are scattered unevenly around the
globe
b. Migration =
people travel from place to place to get what they need
early hunters followed the herds of large animals to the Americas
Freedom of religion, etc. to the Americas
5. Region = has unifying characteristics, either physical or
human / cultural
a. Physical Characteristics =
a region's climate or landforms dictate an areas attributes
b. Human / Cultural Characteristics =
the language, culture, customs of a particular region
II. Tools of Geography = geographers use globes and maps
to represent the Earth. Globes tend to be more accurate than maps due to globes being shaped more like the Earth. A map is a drawing of the surface of the Earth or part of the Earth. Globes are the most
accurate, but are awkward to use.
+ Cartography – the act of
mapmaking
A. Map Projections =
ways of drawing the Earth on a flat surface
benefits and drawbacks, show sizes or shape, but distorts
1. Mercator Projection =
most widely used map projections
developed in 1569 by Flemish cartographer
gave sailors an accurate picture of ocean distances and shape of
landmasses
a. Problems with Mercator Projection =
distorts size, especially places that are far from the Equator
Greenland appears as big as all of South America
2. Robinson Projection =
show correct sizes and shapes of landmasses for the most part
fairly accurate view of the relationship between landmasses
and water
used often today
distortion along the edges
B. Special Purpose Maps = geographers have developed many kinds of maps to show
different information. Using this information, you can learn a lot
about a region.
1. Physical maps =
show mountain ranges, bodies of water, etc.
2. Political Maps =
features determined by people
boundaries for countries and states, locale of cities
3. Thematic Maps =
maps that deal with specific topics, that help understand the
connections between geography and history
a. Population Maps =
# of people in a particular area
b. Economic Maps =
how people make a living in an area
c. Battle Maps =
locations of major battles and the routes of advancement and/or retreat
4. Today, cartographers use the improved technology of satellites
and computers to make maps extremely accurate.
