Chapter 4 Flashcards
Sink vs. Source
Area that holds water
Where it goes, where it comes from
Layers of the earth
there are 6
Lithosphere Asthenosphere Upper mantle Lower mantle Outer corer Inner core
Thermohaline
Flow of ocean water caused by changes in density
The Carbon Cycle Equation
Glucose + Oxygen => Water + Carbon Dioxide + Energy
Where are some carbon sources coming FROM out of the earth in the carbon cycle?
Fire
Fossil Fuels
Emissions
Animal respiration waste products
Where are some carbon sources coming TO the earth in the carbon cycle?
Exchange from the atmosphere to the soil and ocean
Hydrological Cycle
Precipitation Transpiration Surface run-off Evaporation Condensation
Phosphorus Cycle
Cycling through water, soil and sediments
Nitrogen Cycle
Animals absorb nitrates through plants Decomposing bacteria starts Ammonification Denitrification Nitrogen is released into atmosphere
Example of Carbon Sink
examples…
Anything that absorbs more carbon that it releases
Examples:
- Plants
- Animals
- Rocks
- Water
Example of Carbon Source
examples…
Anything that releases more carbon than is absorbed
Examples:
- Fossil fuel deposits
- Atmosphere
Perpetual resources
examples…
No matter how many you take it doesn’t diminish the source
Examples:
- Solar pannel
- Windmill
Trophic levels and energy transfers
___% is lost at each level
90%
I = PAT
Impact on the Environment (from humans) =
Population
Affluence
Technology
Externality
- Reaction that some other party feels as a result of the first party
- Usually a negative thing and a price tag can’t be put on it
