remain hot, dry, and dead because it's permanently lost its oceans
c.
become more like Mars, losing most of its atmosphere and freezing
d.
become much less geologically active due to decreased solar heating

- Hellas Planitia includes the word "planitia" which is the latin word for "plain" in its name. The name would seem to indicate thats Hellas Planitia is a low lying plain, yet it is clearly a crater, and a very large one at that. The most probable reason for this discrepancy in its name is because: a. It is a simple naming error that for some reason has so far escaped correction. b. There is a disagreement among astronomers about the true nature of Hellas Planitia. c. Its true nature was not apparent over 100 years ago when it was observed using ground based telescopes. d. Astronomers really know its true nature and misconceptions among the public among the public are not of great concern to them.arrow_forwardDescribe how we use radioactive elements and their decay products to find the age of a rock sample.
