Because it does not directly affect the landform thus why it's considered as a passive agent. Those that do directly affect landforms are tectonic activities, winds, and water flow. Weather only onsets the formations.
Nevertheless, the unifying influence of the monsoons on the Indian subcontinent is quite perceptible. ... These monsoon winds bind the whole country by providing water to set the agricultural activities. Thus, in view of the above the monsoon is considered as a unifying bond for this subcontinent.
The reddish-orange colour of weathering of volcanic ash is most likely due to its iron sulfide content which oxidizes to iron oxide so that limonite is yellow and hematite is red and in ash since it is such fine grained material it weathers more rapidly because it has a large surface area.
