On Ceres was everywhere, a giant pyramid – IA Rsute

Cryovolcanism Ceres “flowed” over the surface and this is not the last role was played by the proximity of the planet to the Sun. For a long period of time such insulation has been a mystery to scientists, but now they are convinced that they know the answer: the fact is that other cryovolcanism has been destroyed. This is the only ice volcano, and it’s weird: volcanoes very rarely appear one by one.

today, this ice volcano is the largest on the dwarf planet. This is the only ice volcano, and it’s weird: volcanoes very rarely occur one by one. For a long time, this isolation was a mystery to scientists, but now they are sure that they know the answer: the fact is that the rest of the cryovolcano was destroyed.

Initially, the attention of specialists was attracted by the fact that on the surface of Ceres can meet just one volcano. It seemed quite strange to scientists, because if in the bowels of the planet, the processes that led to its appearance, they almost certainly was to provoke the emergence of other such mountains.

the Scientists presented a model that suggests that in the past on the surface of Ceres were many volcanoes, and at the same time explains where they went. According to experts, due to the fact that the surface of the cosmic body are not the most solid rock, the ancient “volcanoes-pyramids” over time simply deformed to such an extent that almost nothing is left. The sea was still small due to age of the volcano — just 200 million years. However, as scientists assume, after about 100 million years, “smoothed” it is.

it Turned out, the Sea Mons is the youngest volcano on the planet, and the other was completely destroyed. Millions of years ago on Ceres was probably a lot of spewing ciomaga breaks. However, according to scientists, the bumpy volcanic planet’s surface simply leveled over vremeni. Not erosion as the mountains and volcanoes on the Earth, but simply because the cryovolcano emerged from its shape.

a Team of scientists suspects that the Sea of Mons, only 200 million years, have just not had time to undergo this process.

following this idea, scientists have calculated that the time in which should disappear the mountain of Akhun, and what traces of it can stay. As shown by these calculations, the height of the mountain will decline fairly quickly – for tens of meters per million years. Accordingly, a typical krivulkin will be able to survive on the surface of Ceres very short time by geological standards – about 100 million years, after which its dome will be almost invisible from orbit.

“Flattened” structures of this type, as noted by the geologists, they were found on the surface of Ceres, including in the immediate vicinity of the “pyramid mountains”. Now geologists studying images of other regions of Ceres in search of other remains of cryovolcanism, the detection of which will help to understand how often they were eruptions on Ceres and what was the main “engine” of their activity.

Ceres was discovered in 1801 and named after the Roman goddess of fertility. 27 September 2007 it was launched the space station Dawn. In 2015 on the images of this research probe was first discovered a mysterious sparkling white spot on the surface of the planet, then cosmic body was the attention not only of scientists but also of many people, in General, far from science. Experts do not exclude that the appearance of these spots are just the processes of cryovolcanism.

Cryovolcanism has been observed on celestial bodies, where he established extremely low compared with the Ground temperature of the environment. In essence, cryovolcanism different from earthly volcanoes, mostly just those that spew not molten rock, and the so-called “Krylovo”, often a mixture of liquid ammonia, liquid methane, liquid water or gaseous and other impurities.
