SS - Western Hemisphere
Teacher notes
1. The western Hemisphere contains South America and North America
(includes central America)
2. The compass rose that shows all of the directions
3. A line of latitude is a parallel line that travels east and west and is measured
from the equator
a. The farther north or the larger the number the colder it gets. 45 N is
colder than 15 N.
i. 90 N is the North Pole
b. The farther south or the larger the number the colder it gets. 62 S is
colder than 22 S.
i. 90 S is the South Pole
4. A line of longitude is a meridian that travels north and south. The Prime
Meridian is at 0 degrees longitude.
5. A map scale tells distance in miles or kilometers (ex. 1 inch equals 20 miles)
6. A physical map is the natural features (rivers, mountains, lakes, oceans,
islands, etc.)
a. Appalachian mountains are from Georgia northeast to Maine
b. Rocky mountains are from New Mexico northwest to Alaska
7. A political map is the manmade features (boundaries, roads, cities, dams,
etc.)
8. Climate is determined by temperature and precipitation
9. There are many regions of the United States. They have different
landforms, temperature and precipitation that make them unique. Be able
to compare and contrast the different regions.
a. Example: The Northeast region is cold and wet. The Southwest
region is hot and dry. The Southeast region is hot and humid. The
Midwest is cool and humid. The northwest region is cool and wet.
Part 2 Economic Interdependence
1. Division of Labor allows a company to make more products quicker and for
less money
2. Productive Resources include:
a. Natural Resources – items from the earth (for example soybeans,
wheat, corn, cattle, sheep, coal, oil, forests, etc.)
b. Human Resources – people
c. Capital resources – machines and money
3. Specialization leads to trade from one region to the next. If your region is
missing a resource, you can trade with another region. For example, The
Midwest trades wheat to the Southeast region for oranges.
4. Regions that trade with each other benefit by having more products
available to the consumers
5. Different regions specialize in the products that they make because they
have different natural resources.
6. Economic Interdependence allows consumers to have more products
7. In South America: The Pampas have grasslands that produce vegetables,
cattle, and sheep
a. The Amazon Basin grows fruits
b. The Coasts produce oil and have lots of people(high population)
c. The Andes produce coal
8. Regions that have good soil are good for farming
9. Humans have changed the physical environment in many ways:
a. Building dams across rivers and streams
b. Constructing highways
c. Building shopping malls
10. Be able to read and interpret circle graphs
