Lava flows

Lava flows

Fig. 7.13 . This Magellan image shows a lava-filled canyon produced when Venusís crust was pulled apart and magma rose within the gap. The lowland plains have many similar canyon systems; typically about 10 kilometers wide and up to 1000 kilometers long, and apparently containing solidified lava flow. This region, located near the equator between Asteria Regio and Phoebe Regio, is about 10 kilometers wide and stretches 600 kilometers to the north (top). (Courtesy of NASA/JPL.)
