Explanation:

First, the mountain topography in Karnataka is broader than the narrow topography of theGhats in Maharashtra. Due to the greater width of the mountains.Second, the slope of the mountain has a direct bearing on the possibility of precipitation.This is borne out by the Ghats of Karnataka where the mountains are gently sloping,compared to the steep slopes of the Ghats in Maharashtra and Kerala.Third, the gentle slope provides a greater area for sunlight absorption and heating leading to greater convection when compared with an abrupt slope i.e. less Ghat area such as that of the Maharashtra and Kerala Ghats.Fourth, the continuous mountain range presents a greater barrier to rain-bearing winds than a range comprising isolated mountains with gaps in between where the winds can easily pass to the leeward side. Unlike in the case of Kerala, the Ghats in Maharashtra and Karnataka are continuous.
