How surprisingly similar the landscape in this area is to the place
where I live in Brazil. (If you're curious:
Anyway, back to your place. I believe you'd call this a dirt road
leading into a private property:
Would you describe this surface as "earth"? Or maybe "compacted"?
I think "sand" would usually mean fluffy sand, such as in beach sand,
like here: https://www.google.com/maps?ll=-29.347317,-49.729185&spn=0.014065,0.047979&t=m&z=15&layer=c&cbll=-29.347303,-49.729198&panoid=nxCzohwftvM2H6wO89EJng&cbp=11,182.99,,0,3.15
Here's a road in Brazil that probably fits the American definition of
However, the surface here is "compacted" according to official
sources. It's hard to tell visually, but it's possible that the
mixture has been compressed.
This is what I believe would be described as "earth" but not
"compacted" (also from official sources):
I wonder if you'd call this "dirt" too. The distinction is quite
relevant for calculation of routes: you can't travel as fast on earth
as can on compacted, and earth is much more likely to turn into sticky
mud that may get you bogged.
Finding a gravel road here was harder than I thought it would be. I
could only get this photo:
It turns out that most preparations that include "some gravel" but
mostly "soil" here fit the definition of "compacted" quite closely.
I think that "earth" and "soil" are similar enough to stay only with
"earth" - but I'm not a native speaker.
I also wonder which names the British would give to each of these surfaces.
