climate change Flashcards
climate change:
The scientific theory that the earth’s climate is being altered by humans
climate change and the green house effect
green houses effect
green house gasses
anthropogenic green house gases
green house effect
the warming of the atmosphere as some of its gasses absorb heat given off by earth’s surfaces
green houses gasses
atmosphere gasses that create the greenhouse effect by absorbing and holding heat in the earths
anthoropogenic greenhouses
green houses gasses created by people
meet carbon dioxide and methane
carbon dioxide: via burning of fossil fuels
Methane:via decomposition of organic material and solid waste
impact of climate change
-global temperature will increase
-significant(total?) melting of the polar ice caps and glaciers
-the impact of pest and disease will increase
-droughts will become more widespread
-large numbers of environmental refugees could be created
our ecological footprint
measures the environmental impact of a persons activities
Types of resources
divided into four categories
1. renewable resources
2. non-renewable resources
3. flow resources
4. other resources
renewable resources
are resources that can be regenerated if used carefully
Eg. fish, forest
non-renewable resources
resources that can be limited and cannot be replaced once they are used up
eg. coal,natural gas,gold
flow resources
resources that are replaces by natural action and must be used when they occur or be lost
eg. sunlight,wind
other resources
resources that do not fit into the other three categories
eg. niagara falls,rocky mountains
other resources and the grand canyon
-the grand canyon generates a lot of money(7 hundred ten million dollars)
-gives people jobs
-generating money for the local economy
How do we increase our supply of non-renewable resources
we can’t increase our supply of non-renewable resources. so we must use them sparingly
