I'm looking for a term that can describe any form of effect on a ground. Say it's rained, well, the ground would have water on it. It doesn't matter if it's asphalt, dirt, grass, or sand, if it's rained, the water has an affect on the ground. Other things that would apply here are for example, dust on the ground, snow on the ground, etc.
The necessity for this term comes from game development (as so often). I have sprites for the ground, but those sprites can be covered with specific kinds of effects: Rain-Effects, Snow-Effects, Dust/Sand-Effects, etc. I need a term to group those things together.
I suspect that from a purely semantic standpoint, rain soaking into dry soil would still count, though the other two wouldn't. However in this specific example, I don't care as much about the interaction between the ground and whatever has an effect on it. Rather, just what those conditions could be called.
