One of the major goals of ancient
geographers was to measure the size
and shape of Earth. The appearance
of Earth’s shadow on the eclipsing moon
proved to most people that Earth was
spherical. In the 200s B.C. Greek
geographer Eratosthenes used angles
of the sun over a specific distance to
calculate the circumference of Earth.
His estimate was off by only a few
hundred miles.
The Elements of Geography
• Geographers are specialists who
describe Earth’s physical and human
features and the interactions of people,
places, and environments.
(pages 19–20)
List some of the tools geographers
might use to describe the features of
Earth and the relationships between
them.
Geographers might use maps, atlases,
charts, measuring devices,
thermometers, and barometers to
describe the features of Earth and the
relationships between them.

The Elements of Geography (cont.)
(pages 19–20)
• Absolute location The exact latitude
and longitude at which a place is found
on the globe is its absolute location. 
Click the mouse button or press the
Space Bar to display the information.
The World in Spatial Terms
Spatial relations means “relations in
space”: how places, people, and features
of the earth are connected because of
their locations. 
• Relative location Relative location
describes a place’s location in relation to
another place.
(pages 20–21)
When is it useful to know the absolute
location of a place? When is it useful to
know its relative location?
Absolute location is useful for a team of
explorers trying to find a ship that had
sunk, like the Titanic, for example.
Relative location is useful for giving
directions to travelers.

Places and Regions
• A region, larger than a place, is a group
of places that are united by shared
characteristics. 
• A formal region, or uniform region, is an
area defined by a common characteristic.
• A place is a particular space on Earth
with physical and human meaning. 
(page 21)
Click the mouse button or press the
Space Bar to display the information.
Places and Regions (cont.)
• A perceptual region is defined by
popular feelings and images rather than
by objective data.
• A functional region is a central place
and the outlying areas linked to it by
transit systems, for example. 
(page 21)
Give some examples of a place, a
uniform region, a functional region,
and a perceptual region.
Possible answer: The city of Philadelphia
is a place. The Pennsylvania anthracite
coal region is a uniform region. The
Delaware Valley is a functional region.
Pennsylvania–the Keystone State–is a
perceptual region.

Human Systems
• People affect the earth by settling it,
forming societies, and migrating. 
• People also move goods and ideas
to new places.
(page 22)
What historical movements of people and
ideas have changed the United States?
Possible answer: Native American societies
were greatly changed when Europeans began
to settle North and South America. Forced
migration of African Americans, waves of
European immigrants in the late 1800s, the
westward movement across North America,
legal and illegal immigrants from Latin
America, and Asian immigration following the
Vietnam War have also changed the United
States.

The Uses of Geography
• Geographers provide important
information about the planet’s physical
features and processes, living things,
and human systems. Such information
describes the planet and contributes to
planning for future needs.
(page 22)
What can a geographer tell you about
your environment?
Possible answers: Geographers can
describe a place’s land [flat, mountainous]
and water [salt or fresh]. They can also give
the distances between all the places in a
region, and can describe the temperatures
and precipitation levels at different seasons
of the year. Geographers can also interpret
population patterns and explain cultural
relationships.

The Geographer’s Craft
Click the Speaker button
to listen to the audio again.
Cartography, or mapmaking, began
to develop in the Age of Exploration.
Explorers such as Christopher Columbus
and Ferdinand Magellan drew rough maps
of the lands they found across the Atlantic
Ocean. By the early 1500s, European
maps showed entire unexplored
continents between Europe and Asia.
Branches of Geography
• Human geography, or cultural
geography, studies human activities
and their relationship to the
environment.
• Physical geography focuses on the
study of Earth’s physical features. 

• Technology Geographers use
advanced technology–satellite photos,
radar, and geographic information
systems (GIS)–to study the
environment, the weather, and human
settlement patterns.
(pages 24–26)
Why do geographers often rely on maps
rather than on verbal descriptions?
Geographers rely on maps because
they can show a great deal of
information quickly. For example, maps
may show relative distances, elevation,
crops, population, and resources at a
glance. Verbal descriptions take much
longer to read.

Understanding Graphs
Graphs are visual representations of statistical data. Large
amounts of information can be condensed when presented
in graphs. Studying graphs allow readers to see
relationships clearly.
Learning the Skill
The three main types of graphs present numerical information.
Line graphs record changes in data over time. The vertical axis
(y–axis) shows units of measurement, and the horizontal axis
(x–axis) shows intervals of time. Bar graphs use bars of
different lengths to compare different quantities. Circle graphs
show the relationship of parts to a whole as percentages. To
understand a graph: 
• Read the graph title to identify the subject. 
• Study the labels to understand the numerical information
presented.

    One of themajor goals of ancient geographers was to measure the size and shape of Earth. The appearance of Earth’s shadow on the eclipsing moon proved to most people that Earth was spherical. In the 200s B.C. Greek geographer Eratosthenes used angles of the sun over a specific distance to calculate the circumference of Earth. His estimate was off by only a few hundred miles.
