We are the correct distance from the sun allowing liquid water..
Nutrient Recycle allowing life to form |
|
|
Term
| What planets do not have appropriate temp for life? |
|
Definition
|
|
Term
|
Definition
| Mercury is so small it cant hold atmosphere and GHG so SW radiation from sun warms it |
|
|
Term
| What is the most important element necessary for life to exist? |
|
Definition
|
|
Term
| Why is carbon one of the most important elements? |
|
Definition
| it is a apart of all living organisms and it is a GHG |
|
|
Term
| What are the three carbon cycles? |
|
Definition
Short term terrestrial cycly
Short term marine Cycle
Long term carbon cycle |
|
|
Term
| Define Short Term Terrestrial cycle |
|
Definition
| Photo synthesis and respiration of land plants which take C02 in from atmosphere but also add it back |
|
|
Term
| Define Short Term Marine Cycle |
|
Definition
| the growth of organisms that take C02 from the water and atmosphere |
|
|
Term
| Define Long Term Carbon Cycle |
|
Definition
| addition of GHG by volcanic activity, addition and loss of them by weathering and loss through burial |
|
|
Term
| What are carbon reservoirs? |
|
Definition
| components of the Earth system that temporarily hold carbon |
|
|
Term
| What are the six reservoirs? |
|
Definition
Rocks-biggest
Ocean Water
Fossil Fuels
Soil and Sediments
Atmosphere
living organisms |
|
|
Term
| Are reservoirs permanent? |
|
Definition
| No temporary they may loose some to other reservoirs and gain from other reservoirs |
|
|
Term
| Describe inflows and outflows? |
|
Definition
| Example humans release carbon to the air which is an inflow for the atmosphere while and outflow for the atmosphere at land biota through photosynthesis |
|
|
Term
|
Definition
| When inflows equal outflows. Pertubations will move it away from stable state but if stable it will return to its orgiginal state |
|
|
Term
| Is the atmosphere stable? |
|
Definition
| on an annual scale it is however seasonally it may not be. |
|
|
Term
| What is the keeling Curve? |
|
Definition
| it exhibits a curvilinear relationshiop which shows that it atmospheric C02 levels are rising at a progressivley faster rate |
|
|
Term
| organic Chemical Definition of carbon |
|
Definition
| one carbon atom bonded with another carbon atom or a hydrogen atom. Ex: Methane (CH4... one carbon 4 hydrogen) |
|
|
Term
| Define inorganic Carbon Molecules |
|
Definition
Carbon bonded to anything but other carbon or hydorgen
EX: C02 carbon and oxygen= inorganic |
|
|
Term
| Earth system definitoon of organic carbon |
|
Definition
| carbon that is stored, moved and transformed by living organisms |
|
|
Term
|
Definition
| carbon that is stored, moved by physical means inside and outside of organisms |
|
|
Term
Is CO2 organic or inorganic?
(earth systems definition) |
|
Definition
|
|
Term
|
Definition
|
|
Term
|
Definition
| bonded to anything but oxygen |
|
|
Term
| Why is carbon easily coverted to oxidized form? |
|
Definition
| oxygen is highly reactive |
|
|
Term
| What does phot synthesis involve |
|
Definition
| c02 + H20 + sunlight = CH20 (carbohydrate)+ 02 |
|
|
Term
| what does respiration by living organisms involve? |
|
Definition
| CH20 +02 = C02 + H20 + chemical energy |
|
|
Term
| what does methanogeniesis involve |
|
Definition
| organic matter decomposing anaerobically and methane is produced |
|
|
