Earth's
global
systems include the
atmospheric
system,
hydrosphere
system,
biosphere
system, and
lithosphere
system
Equilibrium
is a state of
balance
within systems where
inputs
and
outputs
are
balanced
to maintain
stability
Any
disturbance
to a system can affect its
balance
and cause a
change
Positive
feedback
amplifies
change
and moves the
system
further away from
balance
Negative
feedback
nullifies
/ returns a system towards
equilibrium
and
counteracts
the
impact
of earlier
changes
in the system
Dynamic
equilibrium refers to
constant
short-term
adjustments through
negative
feedback to maintain
balance
This system involves inputs and outputs of both energy and matter.
A)
Open system
1
Which system has transfers of energy both into and beyond the systems boundary but no transfer of matter
A)
Closed System
1
Which system has no interactions with outside boundaries (no inputs or outputs of either energy or matter)
A)
Isolated system
1
The
water cycle
is an open system as it receives energy from the sun which causes
evaporation
,
precipitation
and
runoff.
Cascading systems
are where energy and material are transferred from one sub-system to another
Components of a system
A)
Inputs
B)
Outputs
C)
Energy
D)
Stores
E)
Processes
F)
Flows / Transfers

When the output of one subsystem becomes the input for another subsystem it is called?
A
cascading system
This is an example of what type of feedback:
A)
Negative Feedback

On a
local
scale the carbon and water cycles are both open systems, but on a
global
scale, they are closed systems
How much water is accessible to humans:
A)
0.9%
