Unit 3 Flashcards
What are natural resources?
Natural resources are materials or substances that occur naturally in the environment and are valuable to humans.
Distinguish between recycling, reducing, and reusing.
Recycling converts waste materials into new products, reducing conserves resources and minimizes pollution, while reusing involves finding new ways to use items instead of discarding them.
Is soil a renewable resource? What is the difference between extensive and intensive farming?
Soil is renewable but forms slowly. Extensive farming uses large areas with minimal inputs, while intensive farming maximizes production on a smaller land area with high inputs.
What is the Forest Stewardship Council (FSC)? What groups make up this council?
The FSC is an organization promoting responsible forest management. Groups include environmental organizations, indigenous peoples, forest owners, timber companies, and retailers.
How will climate change impact forest regions?
Climate change can affect forests through rising temperatures, altered precipitation patterns, increased extreme weather events, and the spread of pests and diseases.
What happened to the East Coast Cod and the West Coast Salmon? What is the Marine Stewardship Council?
Overfishing contributed to the decline of East Coast Cod and West Coast Salmon. The MSC is an organization certifying fisheries for sustainable practices.
What are the differences between pelagic, groundfish, and shellfish?
Pelagic refers to open water, groundfish to ocean floor dwellers, and shellfish includes creatures with shells like clams and crustaceans.
How does the inshore fishery differ from the offshore fishery?
The inshore fishery operates closer to the coast with smaller vessels, while the offshore fishery involves deeper waters and larger vessels.
Why is a continental shelf an ideal place to fish?
The continental shelf is ideal for fishing due to its shallow, nutrient-rich waters that support a diverse marine life.
How will climate change affect the world’s fisheries?
Climate change can disrupt marine ecosystems, affecting fish distribution, abundance, and migration patterns, potentially leading to declines in certain species.
What is a flow? A store? Groundwater?
A flow is continuous movement, A store is where water is held for varying amounts of ‘residence’ time, and groundwater is water beneath the Earth’s surface.
Describe the Water Cycle. What is potential evapotranspiration?
The Water Cycle involves evaporation, condensation, and precipitation. Potential evapotranspiration is the theoretical amount of water that could evaporate and transpire from an area.
What is Canada’s renewable and non-renewable energy makeup?
Canada’s energy mix includes renewables like hydroelectric, wind, and solar, as well as non-renewables like oil, natural gas, and coal.
What are minerals? Provide examples. What is ore?
Minerals are inorganic substances with a specific composition. Examples include quartz and feldspar. Ore is rock or mineral from which valuable substances, like metals, can be economically extracted.
Distinguish between mineral reserves and production.
Mineral reserves are estimated recoverable amounts, while production is the actual mined and marketable amount.
