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 building. Orogeny is the process of mountain building, and may be studied as a tectonic structural event, as a geographical event and a chronological event, in that orogenic events cause distinctive structural phenomena and related tectonic activity, affect certain regions of rocks and crust and happen within a time frame.
Subduction zones are sites of high rates of volcanism, earthquakes, and mountain building. Orogenesis, or mountain-building, occurs when large pieces of material on the subducting plate (such as island arcs) are pressed into the over-riding plate or when subhorizontal contraction occurs in the over-riding plate.ubduction zones dive down into the mantle beneath 55,000 kilometres of convergent plate margins (Lallemand, 1999), almost equal to the cumulative 60,000 kilometres of mid-ocean ridges.
