Devana Chasma
Devana Chasma is a weak extensional rift zone on Venus, with a length of 4000 km, a width of 150–250 km, and a depth reaching 5 km. Most of the faults are facing north–south. The rift is located in Beta Regio, a 3000 km rise created by volcanic activity. Mantle plumes rising from the bottom are the reason behind the formation of the rift zone. The slow extension rates in the rift may be driven by the same reason.Kiefer, W. S., and L. C. Swafford.

Devana
Devana ( pl, Dziewanna , la, Dzewana), Zevana ( pl, Ziewanna), less often Zievonya ( pl, Ziewonja, Zewonia) is the goddess of wild nature, forests, hunting and the moon worshiped by the Western Slavs. In the sources, she was first mentioned in the 15th century by Jan Długosz, who compared her to the Roman goddess Diana. ''Dziewanna'' is also a Polish name for ''Verbascum'', and the etymology of the word is unclear. After strong criticism from Aleksander Brückner, researchers rejected her authenticity, but nowadays it is accepted by an increasing number of researchers. Sometimes, in folk rituals, she performs together with Morana. Etymology Proto-Slavic name for ''Verbascum'' is reconstructed as ''*divizna'' (cf. pl, dziwizna, Czech and , ), with secondary form as ''*divina'' (cf. pl, dziewanna, ). That word has an Proto-Balto-Slavic origin and appears in Lithuanian language as e.g. ''devynspė͂kė'', ''devynjėgė''. The only cognate from outside the Balto-Slavic group m ...

Venus Map With Labels
Venus is the second planet from the Sun. It is sometimes called Earth's "sister" or "twin" planet as it is almost as large and has a similar composition. As an interior planet to Earth, Venus (like Mercury) appears in Earth's sky never far from the Sun, either as morning star or evening star. Aside from the Sun and Moon, Venus is the brightest natural object in Earth's sky, capable of casting visible shadows on Earth at dark conditions and being visible to the naked eye in broad daylight. Venus is the second largest terrestrial object of the Solar System. It has a surface gravity slightly lower than on Earth and has a very weak induced magnetosphere. The atmosphere of Venus, mainly consists of carbon dioxide, and is the densest and hottest of the four terrestrial planets at the surface. With an atmospheric pressure at the planet's surface of about 92 times the sea level pressure of Earth and a mean temperature of , the carbon dioxide gas at Venus's surface is in the ...
