Five Themes of Geography Environment and Interaction
Five elements of environment • Read pages g22 –g26 • As you are reading pages 24, 25, 26 take point form notes on the 5 elements using LM8( be sure to note important vocabulary) • Answer question 2 in the THINKING IT OVER Section on page 26 • Read over pages g27 –g31 • Using LM10 answer questions 1 and 3 on page g31 • Answer the following questions • Is the cod fish story an example of adaptation or modification? Explain. • What about Oil Under the Atlantic? Nickel in Labrador? • THIS NEEDS TO BE COMPLETED FOR NEXT CLASS
Five elements of environment • All living things move, for various reasons, using different methods, from place to place • Every place has an environment, where people face challenges and opportunities • All living things are affected by their environment (the physical surroundings and conditions • Humans respond to two different types of environment: physical and social • It is different in the animal kingdom, they depend on their natural environment for survival
Five elements of environment • Last class you read about the 5 environmental factors • What are they? • Landforms: • Climate: • Water: • Soils: • Natural Vegetation: • Forests, grasslands, wetlands, and Arctic tundra: plants that developed in response to climate and soil conditions • natural features of the landscape, natural physical features of the earth's surface • a mixture of worn rock particles and decayed organic material from natural vegetation. • the long-term average of weather conditions at a particular place. • lakes, streams, rivers, oceans that are part of the surroundings
Human/Environment interaction • Human-environment interaction looks at the relationships between people and their environment; how people adapt to the environment and how they change it • Discuss - What is the difference between human adaptation and human modification of the environment? • It’s important to note that environment and interaction as themes in geography are VERY hard to separate • A human modification of the environment means that humans have actually changed some part of the physical environment (i.e. building a dam) • A human adaptation to the environment is a change in human behaviour to cope with environmental conditions (i.e. different clothing)
What Happened to the Fish? • Cod once flourished around Newfoundland and southern Labrador • Fishing started by the Europeans in the 1500’s • Fishing boats got bigger, bigger, and BIGGER and the cod population became vastly depleted • By 1989 it was too late for the cod population • In 2003, the government of Canada closed the Newfoundland and Labrador cod fishery indefinitely. • This is an example of humans depending on the environment for their livelihood • This example also illustrates humans can modify the environment with serious consequences • It also illustrates how the environment and interaction are incredibly difficult to separate
Interaction in geography • Read pages g34 to g36 • Answer questions 1, 2, 3, 4 under the THINKING IT OVER section on page 36 • You can work with your group on these questions • Read pages 37 - 39 • On page 41, under the PUTTING IT ALL TOGETHER section, answer questions 1 and 2
Interaction • The interaction theme includes opportunities humans take to make use of the environment. • Can you think of some examples of opportunities in which we make use of our environment? • earth gives people opportunities to provide themselves with necessities: food, water, clothing, heat, and shelter. • we clear forests for farming and build port cities at natural harbours. • We use waterfalls and dam up rivers to create electricity • we blast transportation tunnels through mountains. • This theme also deals with challenges in people’s interaction with the earth • Can you think of any challenges that people face in interacting with earth? • One type of challenge centres on different opinions about using the earth’s resources. • Another challenge is the incredibly destructive power of the earth. • Volcanoes, earthquakes, and mudslides can sweep away whole communities in minutes. • Tornadoes, hurricanes, and blizzards unleash great devastation.
On your MARK • If all humans were taken off the face of the earth, what would be left behind? • This is our cultural landscape, or the mark that humans leave on the earth’s surface as a result of our interaction with it. • Urban landscapes are the result of great changes to the physical environment. Forests were cut down, hills were levelled, and valleys were bridged. Streams may have been dammed or diverted into drainage canals.
