Geographic FeaturesGeographic 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.

• 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.

Carbon Dioxide LevelsCarbon 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

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.

ClimateClimate• 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.

ClimateClimate• 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 OceanAtlantic Ocean

• The saltiest of all the major oceans in the world

• The salinity ranges from 33 to 37 parts per thousand

Weather DisturbancesWeather 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.
