> If we use the US Department of Agriculture’s soil textural triangle, sand is any granular material that is at least 85% sand…
Cool, I just added a single grain of sand to a tonne of snow, now I have a tonne of sand. How convenient.
I don’t understand how you got that conclusion — 1 grain of sand is not 85% of the [ton of snow + 1 grain sand]
How does that one grain become 85% of a tonne?
If you add a single grain of sand to a tonne of snow, it’s not 85% sand.
