Changes in Accounts Receivable Turnover Ratio. If your turnover ratio is decreasing, this means that your average collections are taking longer. The reverse is true if you turnover in days is decreasing; this means that your average collection period is decreasing also.hanges in Accounts Receivable Turnover Ratio.

Mountain formation refers to the geological processes that underlie the formation of mountains. These processes are associated with large-scale movements of the Earth's crust (plate tectonics). Folding, faulting, volcanic activity, igneous intrusion and metamorphism can all be parts of the orogenic process of mountain building.
Key Topics. The Mountains Go Up  Mountain Building. To understand the formation of the Rockies, we need to understand Plate Tectonics. According to this theory, the surface of the Earth is made up of a series of plates, each of which move relative to the others. At one time, all the continents were joined into one large land mass known as Pangea.
