Geologic History on Earth and Mars

Author: Hugh Bollinger/Monday, April 9, 2018/Categories: natural history, photography, space science, art and design, environment, adventure

With more and more satellite images being acquired from Mars, striking geologic comparisons between Mars and Earth are now possible. NASA has shown this by comparing pairs of images. One example are rock structures thrusting from the flat, dry, landscapes of northwestern New Mexico and a Martian desert plain. Protruding from the New Mexican desert is the extinct, volcanic spire of Shiprock, a lava rock "plug", is compared to landscape terrains on Mars. Volcanic activity on Mars created similar razor-like, shapes visible as virtical, triangular walls.

Additional research will add to understanding how similar and for how long such processes worked on Mars and if they're still in progress.
