Scientists said that they managed to explain the appearance of mysterious "crowns" on the surface of Venus. According to the researchers, mysterious plateaus are a consequence of the action of streams of hot rocks that periodically rise up and destroy parts of the planet's surface, reports Space. Com.
New discoveries mean that Venus is much more active than anticipated. During the research, scientists conducted a number of laboratory experiments. The researchers filled the glass mock-ups with a suspension of silicon particles similar in composition to the interior of Venus. Scientists heated and dried the liquid, simulating the appearance and disappearance of plumes. Tests showed that hot currents rose from the lower layer of the planet, and then settled on the surface, destroying the hard surface. Thus, fragments of the cortex drowned inside the mantle because of its high density.
