A study of the history of the emergence of deep valleys in the Arctic of Mars showed that 50 thousand years ago the Red Planet experienced a rapid climate change.
The US magazine Sciantofic Reports published an article on the matter.
Alexis Rodrigues, one of the study’s authors, senior researcher at the Planetary Institute in Tucson, USA, said, “The theoretical scientists consider that the layers of ice in the mid-latitudes of Mars formed after the melting of its polar caps at a time when the axis of the planet was tilted, Deep valleys in the north pole of Mars. ”
He recalled that the poles of Mars are covered by the two large ice caps that differ from the two caps on Earth in terms of their structure and dimensions and are composed of frozen water and carbon dioxide gas. The latter was only attended in Antarctica, as for its quantity, it can be compared to the size of the gaseous envelope of Mars.
As for the north pole of the red planet, it is split by a large number of huge valleys, several kilometers deep and tens of kilometers long. It forms a spiral-shaped structure whose nature remains a mystery to planetary scientists.
Alexis Rodrigues, however, believes he has solved this mystery, the scientist and his colleagues consider that the spiral decorations of the valleys appeared 50 thousand years ago when the tilt of the axis of Mars changed, to the melting of some parts of its northern cap directed towards its equatorial line by the influence of sunlight.
The world believes that this phenomenon has become possible as a result of climate change and the rise in temperature in the Arctic of Mars.
And that the subsequent study of deep valleys and ice sheets in the Arctic of Mars will allow scientists to follow the changes in the climate of the Red Planet, and will allow the discovery of sources of water there.
