Geomorphology

System can not maintain its functional operation therefore adjust are made at a new operational level.

• Feedback that encourages a respones in a system
• Tendency to continue or magnify impacts
• Leads to Stability

Balance between opposing forces such that any changes in any of the controlling variables will necessitate a corresponding response in the dependent variables to maintain overall system stability.

Forces on earth's surface

Forces within earth's surface

Stable equilibrium exist because there is no trigger (threshold) to intitate change.

A state of an open system wherein properties are invariant when considered with reference to a given time scale, but within which its instantaneous conditions may oscillate due to the presence of interacting variables.

Set of objects together with relationships between objects are between their attributes.

Consists of flow of engery and/or mater from one object to another; we attempt to understand the processes that cause movement but do not understand quantitative relationships that exist between objects related t the transfer of engery.

Integrates characteristics of both morphological and cascading systems (1 or more ) of both and a model of the process involved in the movement, storage and transformation of energy and or matter between systems objects and we can fully understand the form of the system.

balance of tendencies brings about a static condition of certain ststem properties, both absolutely and relatively.

Tendency for a system to move back toward a previous equilibrium condition after being distrubed by limited external forces.

Small displacement leads to a greater displacement, usually terminated by the achievement of a new stable equilibrium.

when stable equilibrium obtains only in the abscense of a suitable trigger.

Balance fluctuations about a constantly changing system condition which ahs a trajectory of unrepeated average states through time.

• Brings together both morphological and cascading systems.
• Cause and Affect

Engergy may transfer into and out of system but no mass.

No energy or matter leaks out of the system and none comes in.

Matter and engergy flow into and out of a system freely.

Most of earth's systems.
