What is the answer.
Is it arctic geologists per 100,000
So why are there so many arctic geologists in the Amazon?
The South and North American red dots look like they’re the Atacama and maybe Death Valley. In which case it may have something to do with either temperature or lack of water.
You’re pretty close with lack of water, but it’s not exactly that. Note that Antartica is entirely blue and they get very little precipitation.
It’s something that is generally associated with low levels of rain.
Hmm, there’s a few possibilities – cactuses, sand, salt, the level of life in the soil.
All plausible, but it’s hours of annual sunlight.
.. or the amount of moisture in the soil.
