Systems in Water and Carbon Cycles
any system which has external inputs and external outputs
enhances or amplifies an effect by it having an influence on the process which gave rise to it.
dampens or reduces an effect by it having an influence on the process that gave rise to it
Methane release from the tundra
example of positive feedback in the carbon cycle, rising temps release methane which rises temps
Extra plant growth
example of negative feedback in carbon cycle as plants absorb carbon reducing rate of climate change
lack of change in a system as inputs and outputs remain in balance over periods of time.
These have no interactions with anything outside of the system boundary. There is no input or output of energy or matter
these have transfers of energy both into and beyond the system boundary but not transfer of matter
the transfer of mass and energy along a chain of component subsystems, such that the output from one subsystem becomes the input for the adjacent subsystem.
River sediment into coastal zone
example of a cascading system
the inputs, flows and outputs all associated with the layer of gasses surrounding our planet
the inputs, flows and outputs all associated with the cold, hard solid land of the planet's crust (surface)
the inputs, flows and outputs all associated with the water on our planet
the inputs, flows and outputs all associated with the biology and ecosystems of our planet
