Homework Statement
I am just wondering if my analysis of the following feedback loops are right.
The invariant in this case is Temperature
Solar heating->Temperature->Evaporation cloud cover-> albedo->Solar heating
Second feedback loop
Invariant forest area
Forest area->Plant evapotranspiration and raincloud->rainfall->forest area
Homework Equations
The Attempt at a Solution
Temperature->evaporation cloud cover, it would be a positive coupling hence if more temperature, then more evaporation and cloud cover
Evaporation cloud cover-> albedo, Evaporation is a greenhouse gas , but at the same time it helps clouds form, so I will go with the greenhouse gas trait because evaporation is one of the causes of greenhouse gases. The coupling would be negative
Albedo->solar heating, if the albedo decreases then there would be more solar heating coming to the earth
, so it would be a negative coupling.
solar heating-> Temperature, positive coupling because if more solar heating coming to the Earth then more temperature
Generally it would be a a positive feedback loop
second feedback loop
Forest area-> plant evapotranspiration and raincloud, if the forest area increases then there would be more plants evapotranspirating and more raincloud
Plant evapotranspiration->rainfall, if there is more evapotranspiration and rain cloud then there would be more rainfall hence the vapor condenses and then it produces rainfall
rainfall->Forest Area, this one is tricky, assuming that the process is giving naturally then rainfall will help the forest area to protect from sunlight, so it would be positive coupling
generally it would a positive feedback loop
