Unit 3 Test Review - Resources and Industry Flashcards
(29 cards)
Define natural resource
Natural resources are materials or substances that occur in nature and can be exploited for economic gain.
Examples include water, minerals, forests, and fossil fuels.
What is the difference between a renewable and non-renewable resource? Provide an example of each
Renewable resources can be replenished naturally over time, while non-renewable resources are finite and cannot be replaced once depleted.
* Example of renewable: solar energy
* Example of non-renewable: coal
Renewable resources include wind, solar, and biomass.
List the 3 things that Canada’s economy depends on
Canada’s economy depends on:
* Natural resources
* Manufacturing
* Services
Each sector contributes significantly to the GDP and employment.
Define and provide an example of primary, secondary and tertiary industry
Primary industry involves extracting natural resources, secondary industry involves manufacturing goods, and tertiary industry involves providing services.
* Example of primary: fishing
* Example of secondary: automobile manufacturing
* Example of tertiary: healthcare services
The classification helps understand the economic structure.
Explain exploitation, sustainability and stewardship
Exploitation refers to the use of resources without regard for long-term sustainability. Sustainability is the ability to maintain resource use without depleting them. Stewardship involves responsible management of resources.
These concepts are critical in environmental science.
Understand and explain the triangle diagram of the 3R’s
The triangle diagram represents the hierarchy of waste management:
* Reduce
* Reuse
* Recycle
This visual helps prioritize actions to minimize waste.
Explain how a person can be environmentally conscious by: Reducing, Reusing, Recycling
A person can be environmentally conscious by:
* Reducing: minimizing waste production
* Reusing: finding new ways to use items instead of discarding them
* Recycling: processing materials to make new products
Each action contributes to lessening environmental impact.
How has discarded plastic affected our land and water environments?
Discarded plastic has led to pollution in land and water, harming wildlife and ecosystems.
It can take hundreds of years to decompose.
What are the reasons why industries (businesses) set up where they do?
Industries set up based on:
* Proximity to resources
* Access to transportation
* Availability of labor
* Market access
These factors influence operational efficiency and profitability.
Identify all the resource industries that are a part of Canada
Resource industries in Canada include:
* Forestry
* Fishing
* Mining
* Agriculture
Each sector provides various jobs from extraction to processing.
Define commercial fisheries
Commercial fisheries are operations that catch fish for sale and profit.
They can be local or global in scale.
Why was the Grand Banks area abundant in fish?
The Grand Banks area was abundant in fish due to its rich nutrient waters and favorable fishing conditions.
It is historically one of the most productive fishing grounds.
Explain what happened with the Northern Cod in the East Coast
The Northern Cod population drastically declined due to overfishing and poor management practices.
This led to a moratorium on cod fishing in the 1990s.
Why did the East Coast fishery collapse?
The East Coast fishery collapsed due to overfishing, habitat destruction, and lack of regulatory oversight.
It significantly impacted local economies and communities.
Explain how the Canadian government tried to replenish the stocks
The Canadian government implemented fishing quotas, created protected marine areas, and funded research to help replenish fish stocks.
These measures aimed to restore sustainable fishing practices.
Explain the Swim of the salmon
The Swim of the salmon refers to their migratory pattern from freshwater to ocean and back to spawn.
This journey is critical for their life cycle.
Explain obstacles salmon may face
Obstacles salmon may face include:
* Dams
* Pollution
* Climate change
* Predation
These factors can significantly impact salmon populations.
Explain the issues with farmed fish vs wild fish
Issues with farmed fish include:
* Disease spread
* Environmental degradation
* Genetic pollution
* Use of antibiotics
Wild fish are generally considered healthier and more sustainable.
Define aquaculture
Aquaculture is the farming of aquatic organisms, including fish, crustaceans, and plants.
It aims to produce food and other products sustainably.
Types of farming common in Canada
Types of farming common in Canada include:
* Crop farming
* Livestock farming
* Mixed farming
Each type uses different methods and practices.
What is the difference between extensive vs intensive farming?
Extensive farming uses large areas with low input and low output, while intensive farming uses smaller areas with high input and high output.
Each method has different environmental impacts.
Factors affecting farming
Factors affecting farming include:
* Climate
* Soil quality
* Water availability
* Economic conditions
These factors can influence crop yields and livestock health.
Flooding and Farming
Flooding can damage crops, erode soil, and disrupt farming operations.
It can lead to significant economic losses for farmers.
Explain the greenhouse effect
The greenhouse effect is the warming of Earth’s surface due to trapped heat by greenhouse gases in the atmosphere.
It is essential for maintaining life but can lead to climate change if intensified.
