Abstract: Comparative Geology of the Inner Planets: Geological Characteristics of Earth, Moon, Mars, Venus and Mercury

By

Edward J. Zeller

Through the efforts of N.A.S.A. and the Russian Space programs, we have greatly increased our knowledge of the surfaces of our immediate neighbors in the solar system. Photographs of the surfaces of the moon and Mars will be shown together with similar and contrasting photos of earth surface features. In addition, a summary of the seismic measurements and the lunar rock analysis data from the Apollo program will be presented to provide an overview of the similarities and contrasts between the earth and the moon.

Radar imaging studies conducted by United States investigators and the excellent information provided by the Russian soft landing has permitted us a limited look at the surface beneath the dense and cloudy atmosphere of Venus. Even this restricted view makes it possible to reach a number of interesting conclusions about the planet. Mercury has not been visited by space craft, but radar and optical telescopes have furnished information about the rotational properties as well as some indication of its surface characteristics.

By means of a review of the available data, a basis is provided from which geologic comparisons can be made among the inner planets.
