Scale has two dimensions: Space and 2. Time Therefore, large scale phenomena are generally spatially big and change slowly Small scale phenomena are generally spatially little and change quickly Large scale= low frequency Small scale= high frequency eg Fire regime experienced by a forest (rate of return)Scale has two dimensions: 1.
