How surprisingly similar the landscape in this area is to the place
where I live in Brazil. (If you're curious:
https://www.google.com/maps?q=Porto+Alegre&ll=-30.228926,-51.066213&spn=0.013942,0.047979&t=m&hnear=Porto+Alegre,+Rio+Grande+do+Sul,+Brasil&z=15&layer=c&cbll=-30.228942,-51.066222&panoid=Usk3Tqr5RIfjqj4KVzlz7Q&cbp=11,325.39,,0,7.66).

Anyway, back to your place. I believe you'd call this a dirt road
leading into a private property:
https://www.google.com/maps/@32.704426,-116.720207,3a,75y,160.59h,81.43t/data=!3m4!1e1!3m2!1sH5Ez46TUHWIetR4uLSCy0Q!2e0

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
"dirt": https://www.google.com/maps?q=dom+pedrito&hl=pt-BR&ll=-30.911356,-54.643936&spn=0.110754,0.383835&sll=-22.809099,-45.727844&sspn=1.05575,1.535339&hnear=Dom+Pedrito+-+Rio+Grande+do+Sul,+Brasil&t=m&z=12&layer=c&cbll=-30.911501,-54.644076&panoid=PPforo0GCSl6Olx7vH8-_Q&cbp=11,58.3,,0,13

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):
https://www.google.com/maps?q=Campo+Mour%C3%A3o+-+Paran%C3%A1,+Brasil&hl=pt-BR&ie=UTF8&ll=-24.223158,-52.403901&spn=0.470893,1.535339&sll=-22.231586,-42.793808&sspn=0.265046,0.383835&oq=campo+mour%C3%A3o&doflg=ptk&hnear=Campo+Mour%C3%A3o+-+Paran%C3%A1,+Brasil&t=m&z=10&layer=c&cbll=-24.223158,-52.403901&panoid=0ClYdUrcz7I5OEaTGYF2hw&cbp=11,183.99,,0,4.89

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.
