i've added a line to give soil a better definition that also encapsulates it's relevance .... and I've deleted the earth material used in construction.. but a lot of this really needs a hatchet put to it

I've added a more correct definition of soil which includes the requirement to 'support plant growth' I can add a couple more that are from authorative sources and emphasis the difference between soil and regolith~~~~
