Martian surface. This region is on the northern edge of the Magellan Crater in the Tharsis volcanic region. At centre left are mounds of rock,measuring up to 2 kilometres tall. It is not known how these mounds were formed,but they could be due to subrosion. Subrosion occurs when volcanic activity melts frozen ground water,which erodes underground cavities as it flows away. The cavities collapse due to weight from above,leaving irregular mounds on the surface. Image taken by the High-Resolution Stereo Camera (HRSC) on the Mars Express spacecraft | |
