I think that the two regions would be the Temperate Zone and the Polar Zone, as they're the only climate regions to the south of the 20<span>°S latitude. Check a world latitude map and compare it with a climate map if you're still unsure.</span>
Sun= 696,340 km
earth= 6,371 km
moon= 1,737.1 km
There arent any options and i assume their should be? Lol
I think the answer your looking for is Columbia?
Do correct me if im wrong though
