Lecture 35: The Deserts of Mars
Update: 2006-11-13
Description
Mars, fourth planet from the Sun, is a cold desert planet with a thin,
dry carbon-dioxide atmosphere. The geology of Mars, however, shows
signs of an active past, with hot-spot volcanism, and tantalizing signs
of ancient water flows. While a cold, dead desert planet today, Mars'
past may have been warmer and wetter, with liquid water during the first
third of its history. This lecture will review the properties of Mars,
and discuss the evidences of its active past. Recorded 2006 Nov 13 in
100 Stillman Hall on the Columbus campus of The Ohio State University.
