No one believes a pseudo anonymous coward! Post with your real name and address if you want to have an intelligent discussion.
(I have to assume that is your name)
You are missing the point. When you reply to a coward and they reply back, you have no idea if it is the original coward or a different coward. This makes having an intelligent discussion with cowards impossible. There could be 10 replies all by different cowards. The original coward may never even know you replied because all cowards share the same email account.
The only solution I have found to this problem is to never read or reply to cowards. Problem solved.
Color coding in light blue corresponds to surface composition of unaltered mafic material, of volcanic origin. Mafic material from the crater rim is carved and transported downslope along the gully channels. No hydrated minerals are observed within the gullies, in the data from CRISM, indicating limited interaction or no interaction of the mafic material with liquid water. These findings and related observations at about 100 other gully sites on Mars suggest that a mechanism not requiring liquid water may be responsible for carving these gullies on Mars. (Gullies on Mars are a different type of feature than seasonal dark streaks called recurring slope lineae or RSL; water in the form of hydrated salt has been identified at RSL sites.) [emphasis mine]
In other words, these gullies were formed by flowing lava, not water. Considering Mars’s lower gravity, one third that of Earth’s, we should not be surprised if lava is capable of doing things there that it is not generally capable of doing on Earth. In fact, we should remind ourselves constantly that Mars is an alien planet, and that conditions there are different enough to make any predictions based on our knowledge of Earth very unreliable.
