This image depicts how a mountain inside a Mars' Gale Crater might have formed. At left, the crater fills with layers of sediment. Yellow is for deposits in alluvial fans, deltas, and drifts during both wet and dry periods.

The channels in this image, taken by NASA's 2001 Mars Odyssey spacecraft, are called Hephaestus Fossae and were most likely formed by lava flow and erosion rather than being eroded by water.

Much of the northern lowlands of Mars are thought to be relatively young volcanic flows with varying amounts of windblown dust cover. The lack of impact craters in this image from NASA's Mars Odyssey spacecraft indicate the young age of the surface.

The ancient sinuous river channel shown in this image by NASA's Mars Odyssey spacecraft was likely carved by water early in Mars history. Auqakuh Valles cuts through a remarkable series of rock layers that were deposited and then subsequently eroded.
