Unit 3 Flashcards
Types of industries?
Primary, secondary, tertiary
define the three industries
primary- careers involving extracting renewable, non renewable, flow resources from nature
secondary- industries tbay mass produce things provided by primary jobs,
tertiary- anything involving providing a service to the community
two examples of each industry
primary- miner, oil driller
secondary- brewery workers, factory line workers
tertiary- teacher, nurse
define renewable and non renewable energy sources
renewable- can be continually harvested from nature
non renewable- made by nature through a prolonged process
name two renewable energy sources, two disadvantages and advantages to each
solar - disadvantages: not available at all times, low efficiency. Advantages: produces clean energy with 0 pollution, requires minimal maintenance
wind- disadvantages: inconsistent, infrastructure expensive to install. Advantages: can be used anywhere, produces clean energy
name two non renewable energy sources, two advantages and two disadvantages for each
oil- advantages: convenient, reliable, easy to store and transport. Disadvantages: oil mining produces greenhouse gases, and contaminated local waters
coal- Advantages: economically beneficial by providing jobs, and is energy dense. Disadvantages: impacts health of miners (ex lung disease) and is one of the most polluting ways to produce electricity
economic impacts of alberta’s oil sands
- contributes annual billions in government taxes
-opens jobs, atttacting workers (500,000 workers in the industry)
-positively boosts economy in all canadian provinces - transporting oil to refineries from the landlocked region of alberta costs extra which cuts into profits
environmental impacts of alberta’s oil sands
-extraction of bitumen causes deforestation and damages wildlife ecosystems (surface mining(
-mining methods require large amounts of water, impacting local rivers and surrounding freshwater aquifers
-in situ mining doesn’t disturb the surface of extracting grounds
social impacts of alberta’s oil sands
-harms weather climate
-negatively impacts lives if the first nation community (with concerns like water contamination, wildlife and environmental harm)
-some believe it’s a positive engineering feat, while others believe it’s an environmental disaster (pro economic growth vs pro environmental action)
-
political impacts of alberta’s oil sands
-contributed trillions to canadas GDP in the past 50 years
-due to heavy reliance on oil sand revenues, makes the albert’s government more vulnerable to oil price fluctuations
-government makes loads of money with these oil sands
-pressure from both pro economic growth side and pro environmental action side to make descicions involving oil
define ecological footprint
a measurement of how much of the earth our lifestyle needs
define reuse
an attempt to recycle items by
-can someone else use it
-selling it
-considering our needs vs wants especially when it comes to electronics for disposal and e waste
historical head start
location of raw materials
-manufacturing industries want to locate near the natural recourses they will use, to help reduce transportation costs
market
-the larger the population, the larger their purchasing power and the larger the marker for people who will buy the goods being manufactured
-could lead to more buissnesses locating to this part of an area which increases the population of said area and market
power and freshwater
-many manufacturing industries needs lots of power and want it as cheap as possible, so they use rivers from the canadian sheild to provide hydroelectric power
labour
-manufacturing industries need both skilled and unskilled labour
political factors
-governments may offer incentives such as tax breaks or cheap land as a way to encourage certain manufacturing communities to locate to their community
-governments can also discourage buissness who want to locate in their community (bylaws, high tax, certain regulations) this is because it is a potential threat to the natural environment with too much employment
transportation
-manufacturing industries need fast reliable and cheap transportation
other factors
-desire to be near competitors
-local support/ attitude (does the local community see this business as beneficial or problematic)
-considering sensitive environmental spaces, pollution and how your facility will fit into that
when are industrial location factors used
to consider when the time comes to locate a new manufacturing facility
steps to creating hydroelectricity using a dam
-dams block a body of water to collect a reservoir of water
-once the reservoir of water is released, pressure builds up to force water down pipes that lead to a turbine
-the turbine spins which then caused a generator to spin, producing electricity
-hydroelectricity is harnessed the most between the east of ontario and the maritime provinces
