Unit 1 Geography

Activity 1

What is geography about?

What kinds of topics are covered in geography? List 10 different topics on your activity sheet.

Each member of the group must contribute ideas.

Whomever is the oldest in your group will be spokesperson for your group this time.

Mr. Poen will list topics on the board.

Activity 1 Directions Mr. P will assign small groups. In your desk racks you will find a geog. resource.

Everyone in your group may have a different resource. That’s great!

When directed, look through your source noticing what topics are studied in geography.

Define Geography

Still in your groups, develop a definition that the group can agree on.

Write it on your activity sheet. Each person will turn in their activity sheet. Congratulations for earning your first

grade in Social Studies!

Notes:Unit 1 Geography

I. DefinitionA. Geography is the study of the

earth’s structure, surface, and

place in space.1. It studies the people,

their environments, & their resources.

2. It includeslandforms, bodies

of water, climate,

internal forces, & placein space.

B. People who studyGeography are called:

geographers1. They ask how thenatural environmentaffects:

the way we live and how we affect the

environment.

2. How does geography

help historians understand

the past.

Geography holds clues to past events & cultures.

By showing how people and the land are related, geog. helps explain the past and the present.

II. Subject Areas

A. The study of

The physical features

of the planet including

landforms, and bodies

of water is

Physical

Geography

B. This is the study of how theenvironment and geog.

affects the people:

Cultural Geog.

C. This is the study of

weather.

Meteorology

D. This is the study

of climate (long

term weather patterns)

Climatology

E. This is the study of

the Earth’s

structure:

Geology

F. This studies the

earth’s place in

space. It also

includes othe

celestial bodies

such as moons,

planets, nebula,

comets, etc.

Astronomy

G. This studies maps

and map-making.

Cartography

H. This is the study of

the oceans and

other large bodies

of salt water:

oceanography

Think QuestionsWhich subject area of geog does each fit within? 1. Mining for coal 2. Migration pattern of Arctic herdsmen 3. Planning a vacation route 4. Storm chasers 5. Global warming trends 6. Dropping population of some fish species

in the oceans.

III. Five Themes of Geography To help show the connection between

geography and history, geographers have developed five themes.

A. These are:

-Location-Place

-Interaction between people & their

environment -Movement

-Region

B. Theme: Location

1. Answers /describes:

Where did an event happen?

Where is this place?

2. Two types: Absolute (exact) and Relative

3. Absolute (exact) Location:Tells exactly where

something is located.

4. Way to show this:Uses latitude and

longitude, which are terms used to describe the grid of numbered lines on a map or globe.

5. Relative location: tells the location in relation to something well known.

6. Ways to show this:Sometimes it

is more useful to know the relative location of a place, or its location in relation to some other place.

Is Washington D.C., on the east or west of the United States?

Manteno is 30 miles south of Chicago.

Review

Exact Location Tells exactly where

something is located. Uses latitude and

longitude

Relative Location Tells where

something is located in relation to another place.

C. Themes: Place & Region

1. Geographers generally describe a place in terms of

both physical and human features.

2. The physical features

of a place include

climate, soil, plant life, animal life, and bodies

of water.

For example: New England, has a ___ terrain, a ___ coast, and many deep harbors; because of this the region turned to ____ for a living.

3. People help shape the

character of a place through

their ideas and actions. The human features

of a place include:

the kinds of houses people build as well as their means of transportation, ways of earning a living, languages, and religions.

Think of human features of the American frontier. Major ways of making a living? Building practices?

How does Geog. influence the way of life here?

4. What is a region?

It is a large geographical area

with similar features and characteristics.

5. What are characteristics

of a region?

May be physical, such as its climate or landforms.

Example: The Great Plains is considered a region because it has fairly level land, very hot summers, very cold winters, and little rainfall.

May be human and cultural.

Many of the Russian provinces have different languages than the one spoken in the capital.

6. In what physical region

do we live?

Central Plains

D. Theme: Movement

1. Involves the movement

of three things:People

Goods

Ideas

2. Examples:

It occurs because people and resources are scattered unevenly around the globe.

To get what they need or want, people travel from place to place.

3. As people move, they

meet other people and

exchange…

ideas, technology,& goods.

E. Theme: How the people and their environment interact.

Three ways that

humans interact

with their environment:Humans adapt to their environment

Humans modify their environment

Humans depend on their environment

1. Examples: Adapt: learning how tofarm in ancient times;

-People no longer had to move from place to place

in search of food. Cities developed.Modify: Finding ways to irrigate in dry places.-Change unproductive

ground into farmland.Building bridges over rivers

& roads through mountains

Depend: use rivers to transport goods and people

use rivers and lakes for

water sources for drinking, recreation,

and household needs.

2. Due to advanced

technology people may

alter their environments

dramatically bydrilling and mining

cutting down forest to build communities

Eliminating pests that destroy

crops.

IV. Maps and Globes

A. Advantages of maps

over globes:

-May show a variety of information-population, natural resources-Can zoom in and show

great detail

-Easier to store & carry

B. Advantages of globes

over maps:

Globes show “true” land

shape, distances, &

directions.

Maps show distortion more than globes.

V. Kinds of MapsA. What do each type show?

1. Political

show man-made divisions such as countries and states

2. Physical

shows what the landforms and water features are like.

3. Special purpose mapsshow a very specific theme such

as population density, land use, transportation,

trade, etc.
