Natural Resources
What is a natural resource?
A natural resource is a material found in nature that people use to meet their needs and wants.
What is the word for removing a resource from its environment to be used.
To Extract/Extraction
What is overfishing?
What are fossil fuels made from?
Ancient plants and animal remains.
What is a water footprint?
The total amount of freshwater used by a person, community, or country.
Give two examples of renewable and non-renewable energy.
Answers will vary. Renewable - wind, solar, water, trees, fish, etc.
Non-renewable - Oil, Coal, Fossil Fuels, metals.
What is an ecological footprint?
An estimate of the land needed to support a person's daily resource use.
How is soil formed?
Soil is formed from weathering and erosion of rocks overtime.
Where are metallic minerals usually found?
In rocks formed by intense heat and pressure. Mountains, volcanoes, plateaus, etc.
What is the Frontier Perspective on natural resources?
That all resources are meant for human use.
What defines a resource as renewable
It can be regrown or replaced within a human lifetime/at a similar rate that it is used.
State one environmental concern related to denim production
uses lots of water, lots of chemicals get dumped into the water.
What is Aquaculture?
The farming of fish and other marine life in controlled environments
Where are non-metallic minerals usually found.
Areas where they have been buried by sediment. Valleys, lake beds and bodies of water, plains.
What are the three R's and why are they so important?
Reduce, Reuse, Recycle. They decrease resource waste.
Explain what a flow resource is
A resource that cannot be stored, is constantly moving, and must be where and when it is found.
Why does Canada have so much Timber/Wood resource
Canada has a climate that supports the growth of lots of big boreal forests that survive all year round.
What are some of the effects of Clear-cutting
It destroys lots of habitats, reduces the amount of trees that can store carbon, change the direction of water flow, causes soil erosion.
What makes fossil fuels so good for energy?
They are very energy dense and can be used immediately and wherever you want to use it.
Describe the Preservation Perspective
Protecting natural resources by setting them aside and limiting really limiting their use.
Explain crop rotation and why it is so important
Crop rotation is when farmers rotate which fields their crops are in. This is important because if the same crop is grown in the same location, it slowly destroys the soil by using up all of a certain nutrient, leading to soil instability and soil degradation. Moving crops gives soil the time to replenish the nutrients that were being depleted.
How has technology affected our use of resources?
It allows us to get resources we were previously unable to, and it allows us to get them faster and more efficiently.
Give one Pro and one Con when it comes to Aquaculture
Pros: you only fish the fish you want, you don't have to disrupt wildlife
Cons: fish are often genetically modified, conditions are unclean, diseases in the fish form more often, they can escape infect the wild fish.
Explain how Plants and Animals become fossil fuels and what they turn into.
They are slowly buried by sediments and eventually get close enough the earth's core where they are cooked and pressured from all the sediment above them. Plants become coal, and animals become oil.
Explain virtual water with an example
the amount of water used in the whole process of creating a complete product. Beef - the water that is used for the cow to drink and to grow the crops that it eats, as well as the water used to transport and power the facility the beef is made.
