1. Physical Geography of the United States and Canada: A Land of Contrasts North America’s vast and varied landscape and abundant resources have attracted immigrants and shaped the development of the United States and Canada. The Devils Tower National Monument in Wyoming was formed by erosion. It was named a national monument in 1906. NEXT

25. NEXT Section 2 Climate and Vegetation Almost every type of climate is found in the 50 United States because they extend over such a large area north to south. Canada’s cold climate is related to its location in the far northern latitudes.

26. Shared Climates and Vegetation U.S. and Canada Climates U.S. has more climate zones than Canada U.S.: moderate mid-latitudes, Canada: colder high latitudes Climate and Vegetation SECTION 2 NEXT Continued... Colder Climates Arctic coast is tundra: huge, treeless plain with long, cold winters -some permafrost—permanently frozen ground Rockies and Pacific ranges are highland: colder, sparse vegetation -affect weather in lower areas: block Arctic air, trap Pacific moisture Map

28. SECTION 2 NEXT Moderate Climates North central, northeast U.S, southern Canada are humid continental -cold winters; warm summers; heavy agriculture Pacific coast has marine west coast climate -warm summers; long, mild, rainy winters; mixed vegetation -climate affected by ocean currents, coastal mountains, westerlies -prevailing westerlies—middle-latitude winds blowing west to east continued Shared Climates and Vegetation

30. Differences in Climate and Vegetation Milder Climates Much of U.S. located south of 40 degrees N latitude -milder, dry, and tropical climates Southern states are humid subtropical -hot summers; mild winters; long growing season for variety of crops Central, southern California coasts have Mediterranean climate -dry, warm summers; mild, rainy winters; fruits, vegetables grow well SECTION 2 Continued... NEXT

31. SECTION 2 NEXT Dry Climates Great Plains, northern Great Basin semiarid: dry with short grasses Southwest is hot, dry desert, including Mojave and Sonoran deserts continued Differences in Climate and Vegetation Tropical Climates Hawaii is tropical wet: rain forests, temps around 70 degrees F -Mount Waialeale on Kauai Island is one of the wettest spots on earth South Florida is tropical wet and dry: warm with tall grasses -Everglades—swampland covering 4,000 square miles

34. Effects of Extreme Weather Natural Hazards Warm Gulf air clashes with cold Canadian air over the Great Plains -creates thunderstorms, tornadoes, blizzards Hurricanes sweep the Gulf and Atlantic coasts in summer and fall Heavy rains cause floods along big rivers like the Mississippi Heat, lack of rain bring droughts, dust storms, forest fires SECTION 2 NEXT Map

36. NEXT Section 3 Human-Environment Interaction Humans have dramatically changed the face of North America. European settlements in the United States and Canada expanded from east to west.

37. Settlement and Agriculture Alter the Land Settlement Before humans, land changed due to natural forces: weather, erosion Human settlers adapted to, and changed, the environment First North Americans were nomads, moving from place to place -migrated from Asia over Beringia, a land bridge from Siberia to Alaska -hunted, fished, and gathered plants; settled near rivers and streams Human-Environment Interaction SECTION 3 NEXT Continued...

38. SECTION 3 NEXT Agriculture Agriculture replaced hunting and gathering 3,000 years ago Settlements became permanent -cut down trees for houses, plow fields, dig irrigation ditches -plant corn, beans, squash Today U.S. and Canada are leading agriculture exporters continued Settlement and Agriculture Alter the Land
