Mud_volcanoes_In_Mare_Acidalium,_Mars_03.jpg

Summary

Description	English: NASA wrote this caption for the image: This image in the Acidalia Planitia region of Mars shows numerous round hills that have a large circular depression on their tops. These pitted mounds may be ancient mud volcanoes that formed when liquid mud erupted from underground due to shaking from a nearby Marsquake. Similar to volcanoes formed out of molten rock, or lava, mud volcanoes form as the erupted mud piles up at the surface. Acidalia Planitia was likely a large depression that filled with mud, sand, and other sediments that were transported here by water flowing from regions to the south.
