"WebSome rocks will be made up of grains that are all the same size (or very close), while others will have a variety of grain sizes. In sedimentary rocks, we refer to uniform grain sizes as ‘well-sorted’ while rocks with a variety of grain sizes are referred to as ‘poorly-sorted’. It’s also important to observe the shape of the grains. " - Poorly sorted rock
