They are 532 km long and were named after an albedo feature name.[1] The term "fossae" is used to indicate large troughs when using geographical terminology related to Mars. Troughs, sometimes also called grabens, form when the crust is stretched until it breaks, which forms two breaks with a middle section moving down, leaving steep cliffs along the sides. Sometimes, a line of pits form as materials collapse into a void that forms from the stretching.[2] References{{commonscat|Galaxias Fossae}}1. ^http://planetarynames.wr.usgs.gov/ 2. ^Mars Global Surveyor MOC2-620 Release See also
