Cerberus Fossae – young tectonic fissures thousands of kilometres long on Mars
20 September 2018
Volcanism often goes hand in hand with tectonic shifts in the rock crust on all terrestrial planets and the Moon. Magma bubbles rise up from the planet's interior, making room as they ascend and pour their molten rock over the planet's surface in the form of lava. The emptied magma chambers create cavities, which can cause the rigid masses of rock of the crust to sag and shift.
