The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms. Venus has a topography reflecting its single, strong crustal plate, with a unimodal elevation distribution (over 90% of the surface lies within an elevation of -1.0 and 2.5 km) [1] that preserves ...
Nov 17, 2012 · Rocky ground lies beneath the layers of clouds. But unlike Mars and Mercury, which are both scarred by craters, Venus has a relatively smooth surface. Early in the history of the solar system ...
Geology of Venus. Radar global map of the surface of Venus. The hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990–1994 Magellan mission, is centered at 180 degrees east longitude. The geology of Venus is the scientific study of the surface, crust, and interior of the planet Venus.
Venus is similar in structure and size to Earth, and is sometimes called Earth's evil twin. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. Below the dense, persistent clouds, the surface has volcanoes and deformed mountains.
To an observer on the surface of Venus, the Sun would rise in the west and set in the east, [151] although Venus's opaque clouds prevent observing the Sun from the planet's surface. [152] Venus may have formed from the solar nebula with a different rotation period and obliquity, reaching its current state because of chaotic spin changes caused ...
Surface. Surface. The broiling surface of Venus has been a topic of heated discussion among planetary scientists. The traditional picture includes a catastrophic, planetwide resurfacing between 350 and 750 million years ago. In other words, Venus appears to have completely erased most traces of its early surface.

Does Venus have a lava flow?
Surface. Venus shows evidence of very strong volcanic activity and likely has more volcanoes than our planet. Scientists have never seen an active lava flow on Venus, but they estimate that 80% of the planet's surface is covered by smooth, volcanic plains that are left over from previous lava flows.
