Renewable & Nonrenewable
Used for energy, takes millions of years to form
What is natural gas?
Moving water and wind are examples
What are renewable resources?
Cutting down many trees, causing habitat loss - what is this called? And, is this a renewable or nonrenewable resource?
What is selective cutting and nonrenewable resources
Removing all trees in a large area at once
What are trees and lumber?
If Canada has 10 lakes and each lake contains 500 million liters of water, how many liters of water are in all the lakes combined?
10 x 500,000,000 = 5 billion liters
Replenish quickly, like wind and sunlight
What are flow resources?
Energy from the sun
What is solar energy?
Removing only selected trees
What is selective cutting?
This less destructive logging method involves carefully selecting individual trees.
What is selective cutting?
A forest has 2,000 trees. If 25% are cut down during logging, how many trees are removed?
25% of 2,000 = 0.25 x 2,000 = 500 trees
These resources, like wind and sunlight, naturally replenish quickly. Are they renewable or nonrenewable?
What are renewable resources?
This renewable energy source uses the movement of air to generate electricity.
What is wind energy?
The largest rainforest in the world, threatened by deforestation, is called what?
What is the Amazon?
Removing large sections of forest can lead to soil erosion and habitat destruction.
What is zone cutting? (or zone logging)
If a river flows at a rate of 300 liters per second, how many liters flow in 30 minutes?
300 liters/second x 60 seconds/minute x 30 minutes = 300 x 60 x 30 = 540,000 liters
This resource, found in forests, can be replanted and used repeatedly.
What are trees/lumber?
Moving bodies of water like rivers and streams, and fish populations in oceans and lakes are an example of what kind of resource?
What are flow resources?
This method of logging involves clear-cutting large sections, which can damage ecosystems.
What is clearcutting?
The widespread loss of forests can lead to decreased oxygen production and contribute to climate change.
What is deforestation?
A natural gas reserve contains 2,000 units. If 500 units are used each year, how many units are left after 3 years?
2,000 - (500 x 3) = 2,000 - 1,500 = 500 units
The process of burning coal, oil, or natural gas to generate electricity is called what?
What is combustion?
This flow resource involves the movement of underground water and can be tapped for drinking water or irrigation.
What is groundwater?
The loss of forests can contribute to this global issue, which affects climate and biodiversity.
What is climate change?
Deforestation can cause the loss of this vital gas that trees produce and that humans need to breathe.
What is oxygen?
A river provides 50,000 liters of water each day. How much water does it provide in 7 days?
50,000 x 7 = 350,000 liters
