Kahn, R.; Wenkert, D., 1993, "The Earth Observing System", https://hdl.handle.net/2014/34975, The Van Nostrand Reinhold Encyclopedia of Planetary Sciences, JPL Open Repository
The idea that the climate of Earth has changed is not new. Much evidence has been collected from the sedimentary record indicating periodic as well as secular changes in climate parameters such as surface temperature, precipitation amount, and ice extent and abundance, on many ti... |

Lopes-Gautier, R., 1993, "Extra Terrestrial Lava Flows", https://hdl.handle.net/2014/35005, London, England, JPL Open Repository
Volcanism has been one of the major processes shaping the surfaces of the terrestrial planets. Lava flows have been identified on the Moon, Mars, Venus, and on Juptier's moon Io. The study of extra-terrestrial lavas has largely relied on the interpretation of remotely acquired im... |
