Sediment Transportation

My family and I went on a field trip to some sand dunes in Nevada (yes, this is what it looked like in the middle of winter). The sand dunes are not very evident in this picture (they’re way in the background and behind the cameraman), but sand dunes are an example of sediment transportation. The sediment being deposited here is very small grains of sand, mostly. Some darker dirt surrounded the dunes, but the dunes themselves, obviously, were sand. The sand was well sorted and round. It was very fine compared to the sediment around it. The enviroment it was in is probably on the lower end of the energy scale, just because it’s mainly being transported by wind. If the sediment were to immediately compact into a rock, it would probably look similar to the picture below — or at least the bottom half of the picture.
