E-Lecture

Geography is more than memorizing names and places. Geographers organize space in much the same way that historians organize time. To help organize space, geographers are concerned with asking three important questions about things in the world:
Where is it?
Why is it there?
What are the consequences of its being there?

The five themes of geography help answer these questions:
Location: Where is it located?
Place: What's it like there?
Human/Environment Interaction: What is the relationship between humans and their environment
Movement: How and why are places connected with one another?
Regions: How and why is one area similar to another?

No one theme can be understood without the others. The themes are connected with one another, as are all components of our world. No part of our world can be understood in isolation.
I.Location: Position on Earth's Surface

We use lattitude and longitude to determine the location. Latitude and longitude are two sets of lines that make a grid on the earth's surface. This grid can be used to pinpoint the exact location on the planet that something is. This is how your GPS works.
What are the latitude and longitude coordinates of your location (Shoreham/Wading River)
How many degrees of longitude are Shoreham and New York City seperated by?

II. Place: Physical and Human Characteristics


The theme of place addresses this question: What's it like there? This theme considers the characteristics that make one place different from all other places on earth. Geographers describe a place by two kinds of characteristics; physical and human.

The physical characteristics of a place make up its natural environment and are derived from geological, hydrological, atmospheric, and biological processes. They include land forms, bodies of water, climate, soils, natural vegetation, and animal life.

The human characteristics of a place come from human ideas and actions. They include bridges houses, and parks. Human characteristics of place also include land use, density of population, language patterns, religion, architecture, and political systems. The theme of place helps flesh out information about location. Taken together, the themes of location and place provide a basis for observation in geography. These
themes can be used to help answer the first two questions of geography: Where is it? and Why is it there? With a sense of physical and human place, we can read the
landscape around us and make observations about what we see. we'll explore more
about physical and human places when we look at the theme of region.
Discuss answers to these questions about your place:

How would you describe where you live physically? Is your place flat or
hilly, hot or cold, wet or dry? What natural resources are found there?

What are some of the human characteristics that describe your place? For
example, what types of houses are there? Are patterns of land use
different from those in other parts of the country? What types of industry
are found, and how might they be different from industries in other parts of
the country?
III. Human/Environment Interaction: Shaping the Landscape
The physical and human characteristics of a place provide keys to understanding the
interrelationships between people and their environments. This geographic theme
addresses this question: What is the relationship between humans and the
environment? Three key concepts underlie human/environment relationships:
• Humans depend on the environment:
The natural environment is
made up of living things and non living things. Humans depend on the
natural environment for their basic needs; food, shelter, and clothing.
• Humans modify the environment:
People modify the natural
environment to meet their needs. For example, they build dams, plow and
irrigate fields, and dig mines. They build houses, schools, and shopping
centers on land.
• Humans adapt to the environment:
Humans have settled in
virtually every corner of the world by successfully adapting to various
natural settings. For example, people who live in the northeastern United
States use heating units to keep their homes warm in winter People in
the southern part of the country use air conditioning much of the year to
stay cool in the heat. The ways people choose to adapt to their settings
reflect their economic and political circumstances and their technological
abilities. Studying geography furthers appreciation of our natural
environment and of our cultural differences.
Discuss answers to these questions about the
human/environment interaction
where you live:

What examples of human/environment interaction do you see in your
area?

Do you see evidence of exploited resources?

Do you see changes in the landscape in animal habitats? Are there
changes in the air, water, and soil?
IV. Movement: Humans Interacting on the Earth
The theme movement addresses this question: How and why are places connected
with one another? Relationships between people in different places are shaped by
the constant movement of people, ideas, materials, and physical systems such as
wind. Our world is in constant motion, constantly changing. Like blood flowing through
our bodies, movement brings life to a place.
Discuss answers to these questions about
movement
where you live:

What examples of movement of people, goods, or ideas do you see in your
area?

Has immigration had an impact on your area? If so, what has
happened?

What are the transportation routes in your area?
V. Regions: How they Form and Change
A region is a basic unit of geographic study. It is defined as an area that has unifying
characteristics. The study of regions helps us answer these questions: How and why
is one area similar to another? How do the areas differ? Most regions differ
significantly from adjoining areas.
Some regions are distinguished by physical characteristics. Physical characteristics
include land forms, climate, soil, and natural vegetation. For example, the peaks and
valleys of the Rocky Mountains form a physical region.
Some regions are distinguished by human characteristics. These may include
economic, social, political, and cultural characteristics. The highly urbanized Northeast
Corridor between Boston and Washington, D.C. can be considered a human region.
Other regions are combinations of physical and human characteristics, for example, the
South, Scandinavia, and the Midwest.
Boundaries between regions can be vague. Regions are generally thought of as
large areas, such as the Corn Belt in the midwestern United States or sub-Saharan
Africa. Overhead transparencies will help the teacher demonstrate that a region can
be as small as a classroom learning center, a neighborhood, an industrial park, or a
recreational area.
