Maps
• Other types of maps used when studying
American History include:
– Election maps
– Product maps
– Battle maps
• Maps show connections between
geography and history.
Maps
• Cartographers are mapmakers
• Map projections are ways of drawing the Earth
on a flat surface
– Mercator projection
• Shows true shapes of landmasses
• Distorts size, especially for places far from Equator
– Robinson projection
• Shows correct sizes and shapes of landmasses for
most parts of the world
4 Basic Types of Landforms in the U.S.
1. Mountains
– High, steep, rugged
– Rise to elevation of at least 1,000 feet above
surrounding land
2. Hills
– Lower, less steep, more rounded
3. Plains
– Broad areas, fairly level; few are totally flat
– Not much higher than sea level
4. Plateaus
– Large raised areas; flat or gently rolling
– Range from 100s to 1,000s of feet above sea level
– Basins are plateaus surrounded by mountains
8 Physical Regions of U.S. & Natural Features
1. Pacific Coast
– Tall mountain ranges
– Cascades, Sierra Nevada
2. Intermountain
– Mountain peaks, high plateaus, deep canyons, deserts
– Grand Canyon, Great Salt Lake
3. Rocky Mountains
– Includes some of the highest peaks in North America
– A serious barrier to European settlement
4. Interior Plains
–
–
–
–
Large lowland area
Some parts rich in coal and petroleum; others have fertile soil
Great Plains (western part – dry)
Central Plains (eastern part)

Has different names in different areas
• Green Mountains, Alleghenies, Blue Ridge,
Great Smokies

7.
Gulf Plain – large deposits of petroleum
Atlantic Plain – almost flat
Canadian Shield

8.
Lowland area, hills and plains (mostly in eastern Canada)
Rich in minerals; lacks topsoil for farming
Hawaiian Islands
–
–
8 large islands and many smaller ones
Islands are tops of volcanoes (some are still active)
Physical Regions of the U.S.
U.S. Rivers and Lakes
• The Mississippi and Missouri rivers make up the
longest and most important river system in the U.S.
• This river system flows through the Interior Plains into
the Gulf of Mexico.
• Many tributaries (streams and smaller rivers) flow into
this river system.
– Among them are the Ohio, Tennessee, Arkansas, and
Platte rivers
• The Mississippi carries moisture across the Interior
Plains and serves as a means of transportation.
U.S. Rivers and Lakes
• Borders between nations
– Rivers sometimes serve as political boundaries, forming parts of
borders
• Rio Grande (between U.S. and Mexico)
• St. Lawrence (between U.S. and Canada)
– The Great Lakes form part of the border between the U.S. and
Canada – today, canals connect the 5 lakes, forming a major
inland waterway
• Superior
• Michigan
• Huron
• Erie
• Ontario
