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?

The movement of settlers and their culture to a new country
The growth of machine-powered production in an economy
Environment
Manufacturing

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
![Page 16: Chapter 5: Interacting With Our Environment. Section 1: Natural Resources.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649e705503460f94b6e994/html5/thumbnails/16.jpg)
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
![Page 17: Chapter 5: Interacting With Our Environment. Section 1: Natural Resources.](https://reader035.fdocuments.in/reader035/viewer/2022062314/56649e705503460f94b6e994/html5/thumbnails/17.jpg)
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

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
