On Venus, scientists have discovered indications of geological activity
Scientists have discovered evidence that certain portions of Venus’ surface move about in a similar way to Earth’s.
According to the BBC, Paul Byrne, a professor at North Carolina State University, said, “We’ve discovered a previously unknown pattern of tectonic deformation on Venus, one that is driven by internal motion much as on Earth.”
“It is still evidence of internal motion being represented at the planet’s surface, although being different from the tectonics we presently witness on Earth,” Byrne said.
According to the article, the scientists used data from Nasa’s Magellan probe, which was launched in 1989 and operated until 1994, to define the surface features. According to the BBC, the researchers called these surface formations “campi,” which comes from the Latin word “field” or “campus.”
According to the study, “traditionally, Venus’s lithosphere – its rocky outer layer – was believed to be in one continuous piece, in contrast to the Earth’s, which is split up into a mosaic of movable tectonic plates.”
According to the BBC, “Venus’s lithosphere really possesses some degree of movement – but nowhere near as much as Earth’s,” according to results published in the journal PNAS (Proceedings of the National Academy of Sciences).
The tension, fracture, and deformation observed in Magellan pictures of the surface may be caused by molten rock – magma – seething under the crust, according to the study.
“As a result, Venus’s tectonic activity may mirror that of early Earth, between 4 billion and 2.5 billion years ago, when the heat flux inside the planet was greater and the lithosphere was thinner,” the study said.
The blocks, which are 100-1,000 kilometers (620 miles) long, mirror the Earth’s crust in China’s Tarim and Sichuan basins, as well as Australia’s Amadeus basin and the Bohemian Massif, which underpins most of the Czech Republic, according to the study.
