Early in its history, Mars underwent fluvial erosion that has been interpreted as evidence for a warmer, wetter climate. However, no atmosphere composed of only CO 2 and H 2O appears capable of producing mean planetary temperatures even close to 0°C. that early Mars was cold and dry continue to persist, but the geologic evidence for a warmer and wetter ear-ly Mars is unequivocal. The Geologic Evidence: There are two suites of geologic features that attest to a warmer, wetter climate during the Noachian. The oldest features are modified impact craters, which typically lack crater rims, areMissing: book. A WARM AND WET MARS required for each of these sources to re- plenish the CO2 in Mars' atmosphere. The surface heat flux, Ft, on early Mars would have been determined by the com- bination of heat delivered to the surface by thermal conduction, . with rainfall and surface runoff. The necessity for a cold, dry early Mars has been predicated on debatable astronomical and climatic arguments. A warm, wet early climate capable of supporting rainfall and surface runoff is the most plausible scenario for explaining the entire suite of geologic features in the Martian cratered by:
Early Mars» Like the Earth, the climate of Mars has changed over time. Today, Mars is cold and dry and liquid water is not stable on the surface. However, very early in the planet’s history (more than billion years ago) climatic conditions appear to have been favorable for . These ancient fluvial features all provide clues that early Mars may have had a warm and wet climate, similar to Earth’s. However, this idea has challenges. First, the amount of solar energy entering the atmosphere at the time was considered to be too low to support a warm and wet climate. We have presented the first direct comparison of warm, wet and cold, icy early Mars scenarios in a 3‐D climate model. Because of their generality, 3‐D models allow hypotheses for early Mars to be compared with the geological evidence and tested for internal consistency to a far greater extent than is possible with 1‐D radiative Cited by: Integrating STEAM into the ECE Classroom: Finding and Utilizing the Right Resources for Your Center Amy Koester St. Charles City-County Library District.
