Threshing, Winnowing, Hand-Picking, Separation of Substances, Class 6. Threshing is the process in which stems of wheat or paddy are beaten to separate grains from the stems and from the chaff that cover the grains. Winnowing is the method of separating husk from grains with the help of wind. Husk is very light whereas wheat grains are heavy. The method of hand picking is used to separate ...

When mixed with hot water, the oil sands separates into layers, with the most dense—the sand—sinking to the bottom, and the least dense—the water—rising to the top. Oil usually floats on water, but oil from the Athabasca Oil Sands does not. It is more dense than water, but less dense than sand, so it ends up as the middle layer.
