I mean, a desert is basically just a huge amount of sand but where does it stop, what is beneath? I googled it and it says there’s groundwater but what does that mean, and (how) is that even possible?
Edit: So, actually the main question I wanted to know is if there’s a exact border between sand and rock, or if the sand just gets denser and denser until it’s rock (but I believe the weight must not be that big), like Saturn or something.
(Yes, I know what a desert is but I specifically need to know about this certain type of desert)

A really good question to ask is why are desert plants where they are?
If you look at aerial maps of some remote desert areas, you can see layouts of old villages, and the trees are placed where you might find people.
Then think about like, where all the nutrients are coming from in a soil devoid of them, and you realize, the trees are recycling the villagers
