Venus - Impact Craters: The Venusian surface has been altered by objects from outside the planet as well as by forces from within. Impact craters dot the landscape, created by meteorites that passed through the atmosphere and struck the surface. Nearly a

(size, mass, position in the solar system, presence of atmosphere) and different in terms of other, equally important ones (absence of an intrinsic magnetic field, large atmospheric mass, carbon dioxide composition of the atmosphere, lack of water, very high surface pressure and temperature)....
Explain why the surface of Venus is inhospitable to human life SinceVenushas about the same size and composition as Earth, we might expect its geology to be similar. This is partly true, but Venus does not exhibit the same kind ofplate tectonicsas Earth, and we will see that its lack of...
The fact that Venus is located closer to the Sun than Earth, raising temperatures on the surface to nearly 735 K (462 °C; 863 °F),the atmospheric pressure is ninety times that of Earth, and the extreme impact of the greenhouse effect, make water-based life as we know it unlikely. ...

Photographs of the surface returned by the Venera 9 and 10 landers in 1975 showed a stony desert landscape, while tests for radioactive elements in the crust implied a composition similar to that of basalt or granite. Radar mapping of the surface of Venus was done by the Pioneer Venus, Vene...
The resulting transfer of material from loose grains to bedrock surfaces (and vice versa) could yield misleading results on rock composition; moreover, the generation of comminuted debris would enhance chemical reactions that could affect the composition of the atmosphere. These results are thus ...
Venus - Atmosphere, Orbit, Surface: Since Galileo’s discovery of Venus’s phases, the planet has been studied in detail, using Earth-based telescopes, radar, and other instruments. Over the centuries telescopic observers, including Gian Domenico Cassini
