Chapter 5: Interacting With Our Environment
Section 1: Natural Resources
VOCABULARY
Useful materials found in the environment
Natural resources that must be worked to be useful
Natural resources that can be replaced
Natural resources that cannot be replaced
Natural Resources
Raw Materials
Renewable Resources
Non-renewable Resources
What Are Natural Resources?
Everything people use or consume is made with this
Examples: Water, minerals, vegetation, etc (you?)
Used just as they are found
Trees are the raw materials for paper and wood
Wood is soaked and broken up to create pulp (soup of wood fibers) and machines collect the wet fibers on screen to form paper
Natural Resources
Resources found in nature
Raw Materials
Types of Resources
Renewable
Living
Replaced naturally due to how Earth worksEx. Water through use of water cycle Nitrogen & Carbon
Wind to make electricityComes from differences in how Sun heats EarthEnergy from the sun (Solar Energy)Geothermal Energy
Difference in heat between Earth’s surface & interior
Plants & animals considered renewableMust be managed more closely in order to survive
Rotating Fields(Sustainable Farming)
Non-renewable
Fossil Fuels
Most non-living things fall into this categoryExamples: minerals, metals, gas and petroleumResources must be used carefullyMaterials can be recycled in order to be reused
Type of non-renewable resourceCoal, natural gas & petroleum fall into this category
Created over millions of years from remains of prehistoric living things
Could possibly run out if we continue to use like we do
Oil & natural gas are renewable so living things of today will become fossil fuel later but it takes so long to develop it is of no use for us today.
A Special Resource: Energy
SolarWindHydroelectric
Needed to make use of other natural resources
People in every country need itCertain areas are rich in energy resources, others have very few
May have to buy “energy” from other sources
Types
Energy
Meeting Energy Needs in the Future
Over time: energy use has gone up rapidly
Fossil Fuels are slowly running outwe may need to find an alternate source eventually
Sources that won’t run outWindSunTidalGeothermalBiomass (plant material)
These can be used in place of different fossil fuels
Atomic Powerplentiful but can be dangerousdoes not pollute the air
Ways to help energy?
Momentum
Fascism
Obstruction
Bipartisan
Subsidized
force or speed of movement; impetus, as of a physical object or course of events
a governmental system led by a dictator having complete power, forcibly suppressing opposition and criticism, regimenting all industry, commerce, etc., and emphasizing an aggressive nationalism and often racism.
something that obstructs, blocks, or closes up with an obstacle or obstacles
representing, characterized by, or including members from two parties or factions

State of the Union Vocabulary
Ch. 5 Section 2Land Use
VOCABULARY
Natural surroundings
The large-scale production of goods by hand or by machine
The movement of settlers and their culture to a new country
The growth of machine-powered production in an economy
Environment
Manufacturing
Colonization
industrialization
LAND USE AND CULTURE
What depends on how people use land?Culture & EnvironmentExample?
Environment helps to shape cultureEnvironment & culture changes over time which would change land use
Remember, similar environments do not necessarily mean similar cultureCultural background determines how you will interact with your particular environment
Cultures and Landscape
Land Use and Cultural Differences
Land Use and Economic Activity
People use land and resources to make a livingExamples: Farming, fishing, mining
Factories turn natural resources into materials or productsWay things are produced correspond with economic activity
3 LEVELS OF ECONOMIC ACTIVITY
People use land & resources directly to make products (hunting, mining, fishing, farming)Interact directly with land or sea
First-LevelActivity
People process the products of 1st level activitiesDone by manufacturing in a factory
Ex. Turning corn into cornflakes for cerealFound in urban areas
Known as servicesEx. Delivering cornflakes to grocery stores
Do not produce goods but help sell themExamples?
Second-Level Activities
Third-LevelActivities
Changes in Land Use
Colonization allows new people to change the land based on their cultural practices
Ex. Farmers that move will still farm regardless of where they are going
Before European colonists went to Australia there was no farming or raising animals
They changed the way of land use when they moved
Industrialization has changed environmentCaused urbanizationSpread of cities and suburbs is known as sprawl
Colonization
Industrialization and Sprawl
CH. 5 SECTION 3: HOW PEOPLE EFFECT THE ENVIRONMENT
VOCABULARY
A loss of forest cover in a region
A richness of different kinds of living things in a region
Technology for building structures that alter the landscape, such as dams, roads, and bridges
Man-made, that makes the air, water, or soil less clean
Deforestation
Biodiversity
CivilEngineering
Pollution
First-Level ActivitiesDirect Interaction w/ raw materialsProvide food & resources that people need to live
Countries have grown, so people have to meet challenge of feeding population
Ex. Created new farmland has destroyed grasslands & wetlands but food was needed
Agriculture, forestry & fishing is helpful but can have harmful effects (Examples)Farmers use fertilizer to grow food, it’s needed but is harmful
Creating Farmland
Environmental Challenges
People all around the world are working to find solutions to meeting our needs and helping our environmentExamples of how?
Finding A Balance
Second & Third Level Activities
Industry
Services
Created & transformed environment & landscapes
Provide most of the jobs in developed countriesMain land use in urban areasHave side effects on the environment but create convenience, efficiency & are useful
2nd Level
3rd Level
Both Levels
Provide Jobs & Reshape
Environment
Pollution issuesCan cause higher temperatures or other changes in climateWhat are some things that cause pollution?
Are working to find solutionsGreen vehiclesRenewable energy sources
Reducing pollution may reduce risk of harmful environment changesRecycling
Reduces the amount of waste dumpedSaves natural resources
Finding solutions is a major challengeMust work together to meet this challenge
