Is the geological landscape controlled by gradual and unrelentless processes or intermittent large events with little action in between

ANSWER:

Both the points are of greatest interest as nature has its own rule whether it is controlled by gradual and unrelentless processes or intermittent large events with little action in between.  

EXPLANATION:

A normal rain continued for 2-6 days can cause havoc in the lives of people living upon the surface. This is the case of a gradual process. However, a flood on a silent and slow moving stream is the example of a large event with little action. They are all part of the nature. They are dangerous if they affect the lives of people.
