there is a really great explanation it could be ice When the planets have been initially formed, there was a layering approach, with the heavy components toward the center and the lighter components additional out. The heavier elements are radioactive and 'decay.' In the procedure they heat up, driving water out of the minerals and crystal structures. Was there much water in the early rocks? If we are to believe what we are seeing from asteroids and such, the answer is yes, up to 13% water and in some circumstances more. For example, serpentine is about 13% water, and when it is heated and the water driven out, becomes olivine. Under the surface of our earth we uncover a great deal of olivine. There is no purpose to think it was any diverse on Mars. Both planets show indicators of catastrophic flooding, but on earth we have held the liquid water on the surface due to the fact of our bigger size(gravity) and atmosphere. Mars does not have those two advantages. Nonetheless, water driven out could simply have frozen in spots and remained there. Ice or salt? Each make ideal sense when one considers that minerals would also release salts with the water. Nor is it a matter of scraping at the perfect depth, as it might be for a valuable mineral. It was merely a matter of scraping at all, and at a questionable spot, and checking what has been discovered. tuppence 67 months ago Please sign in to give a compliment.
