1 CH 5 Sec 3 Human-Environment Interaction
Students will understand How North America was originally settled How cities adapt to become suitable to the surroundings Identify methods of overcoming distances in US and Canada Identify one method that most impressed you that people have created or built to allow them to live in a harsh area of US or Canada

2 Early Settlement of North America- first settlers were nomads (move from place to place hunting and gathering) Beringia- land bridge the first settlers (future Native Americans) crossed over from Russia to Alaska years ago Agriculture- Native Americans began growing crops around 3000 years ago Why do you feel that US and Canada among the largest exporters of food today? (look at map P 125) US and Canada grow lots of crops bc Terrain- lots of grassland, Weather- mild, humid (means rain), good soil, lots of land and space

3 Cities- early cities needed to be by water, also important factors of settlement include landscape, climate, weather, and natural resources Montreal- located along St. Lawrence River (on an island), really cold (100* days a yr. below freezing) What can a city do to avoid cold and make living in severe winters more endurable? City is (partially) underground- network of walkways shops, restaurants

4 Los Angeles- located on Pacific, nice climate and weather
BUT what natural resource is LA missing that it needs to survive? Railroad- hundreds of thousands of people began moving to LA when the Southern Pacific completed in late 1800’s Aquaducts- brings water from Northern CA to LA Problems- LA expanded into outlying areas, air pollution, lack of water, earthquake threatened zones

5 Overcoming Distances- large countries, enormous distances, obstacles, and harsh climates made it difficult for early settlers to move around Transcontinental Railroads- completed in late 1800’s connected East and West Coasts in both US and Canada Highways- today people travel by car Trans-Canadian Highway- 4,860 miles from Newfoundland to British Columbia US Interstate Highway System- 46,000 miles of freeways that crisscross the nation (Hwy 10 and 5) Analyze why Canada has one major highway near the US border and the US has highways all over?

6 Overcoming Distances: inland water ways
St Lawrence Seaway-is a canal that connects Atlantic Ocean with Great Lakes most important shipping route in N. AM, Locks- allow ships to be lifted up by closing gigantic gates and fill the area bt gates with water
