Document Summary

Geomorphology refers to the scientific study of the morphology of the surface of the earth and the processes acting on it in the past, present and future. It is not only used on the earth (the moon) and it is an empirical science (being based on observation and experiment). Equilibrium occurs over short and steady time intervals graded time (100-1000 yrs) Negative feedback causes return to static equilibrium involves gradual processes, not disruptive events cyclic time (millions of years) (cid:272)ha(cid:374)ges a(cid:396)e(cid:374)(cid:859)t offsetti(cid:374)g, the(cid:396)efo(cid:396)e the(cid:396)e a(cid:396)e p(cid:396)og(cid:396)essi(cid:448)e changes in the average condition of the system.

Disequilibrium means that there is a period of readjustment in which processes and forms are not in equilibrium.
