Underground Lake of Liquid Drinking water Detected on Mars : room
I am heading to apply my awful ignorance to the issue, which is usually a wonderful way to occur up with completely wrong answers to now solved issues… but it is really fun to use the mind, appropriate?
Mars is smaller than Earth, and significantly fewer geologically energetic. I would hence hope a lot less differentiation of resources and a larger concentration of heavier components close to the floor. In addition, I’d anticipate that any non-planetkilling meteor strikes would leave their deposits on the surface area in essence permanently, because there are no plate tectonics recycling the planetary crust.
On the other hand, there’s probably also some diploma of factor settling that happened at the level of the protoplanetary disk billions of decades in the past, so maybe Mars had significantly less than Earth to work with from the begin – even though on the scale of the Solar system, Earth and Mars are nearly in the very same orbit, so maybe not.
