Resurfacing History and Volcanic Activity of Venus

Abstract Photogeologic principles can be used to suggest possible sequences of events that result in the present planetary surface. The most common method evaluating absolute age a surface remotely is count number impact craters have occurred after formed, with assumption occur spatially random fashion over time. Using additional assumptions, been partially modified by later geologic activity assess time frames for an interpreted sequence events. total on Venus low and spatial distribution taken itself nearly indistinguishable from random. overall implication Venusian much closer Earth its youthfulness than other, smaller inner solar system bodies.
