The fundamental historical factors differentiating Venus and the earth with respect to major secondary properties, despite such great similarities in primary properties, are discussed. The great impact which created the moon and substantially reduced the earth's atmospheric cover was a fundamental point of evolutionary divergence; the absence of an ocean on Venus prevented an earthlike recycling of volatiles and inhibition of subduction. Venus' mantle-rock melts are more dense than their solid matrix at greater-than-8 GPa pressures, thereby sinking at depths below 25 km. Attention is drawn to the problem of reconciling the probability of a voluminous crust with existing indications of substantial strength at depths of only 20-100 km.
