Location
• Northern Hemisphere, between the
Arctic Circle and the Tropic of Cancer
• 65-100 degrees W
• 30-45 degrees N
Time Zones
• Eastern Time Zone
• Mississippi, Alabama, Wisconsin, Illinois,
and some parts of Tennessee and
Kentucky are in the Central Time Zone.
• Northern area has longer days
• New York- 1 more hour daylight than Florida
Rocks and Minerals
• Most abundant minerals are Calcite,
Flourite, Quartz, Celestine, and
Apophillyte
• Coal, some found in the Appalachian
Mountains
• Granite, found in Smoky mountains
• Limestone, mostly along Florida
Eastern Seaboard
• Salt, in Mississippi
Plate Tectonics
• North American
Plate
• East of Mid-Atlantic
Ridge
• Continental and
Oceanic Crust
• Easterly side is
divergent with
Eurasian Plate
Geographic Features
• Mostly flat coastal plains in southern
areas
• Hills and farm land in the
Northwestern areas
• Not many earthquakes, but more
common around the areas of the
Appalachian Mountains.

Geographic Features
• The Great Lakes
•
Consisting of Lakes Superior, Michigan, Huron (or Michigan-Huron),
Erie, and Ontario, they form the largest group of freshwater lakes on
Earth.
Geographic Features
• Appalachian Mountains
Carbon Dioxide Levels
• Air in the Eastern United States contains
an additional 2.7 parts per million of
carbon dioxide from fossil fuel sources.
• In Maryland, Ohio, Pennsylvania, and West
Virginia there was twice as much additional
carbon dioxide in the air at 4.3 parts per
million.
Wind Patterns and Air
Pressure
• Overall wind patterns
and the movement of
fronts in North
America are almost
always from west to
east
• Westerly Winds
• High Pressure in the
Northern Area
• Low Pressure in the
Southern Area.

Climate
• Southern area is hot and humid
• Central area is temperate and humid
• Warm summers
• Northern area is cool and humid
• Cool summers
• Because of the Gulf Stream along the
coast and the Atlantic Ocean, the area is
mostly temperate.
Climate
• Because of the Appalachian Mountians this area has the
second highest annual rainfall
• On the western side of the mountians the air rises and
then descends on the eastern side. The air warms as it
decreases in altitude creating warm currents and an effect
called the “chinook winds.” This along with the low
elevation and latitude creates higher temperatures in cities
closer to the eastern side of the mountains.
• The presence of the Atlantic ocean near the Appalachian
mountains makes the eastern side of the mountains not so
dry. It causes the eastern side to have more precipitation.
Atlantic Ocean
• The saltiest of all the major oceans
in the world
• The salinity ranges from 33 to 37
parts per thousand
Weather Disturbances
• Hurricanes
• They form with the warm air and low pressure in the
Atlantic ocean.
• Occur mostly during late summer towards the southern
area.
• Floods occur because of heavy rainfall.
• The most severe occurred in the mountains of North
Carolina and Tennessee.
• Ice Storms in the Northeastern area.
• New York, northern New Hampshire, Vermont, and
Maine.
Biomes
• Mostly Temperate Deciduous Forests
• Hardwood trees
• There are some evergreen forests
• The tip of Florida is made up of
Savannahs
