Sometime in the distant past Mars was raging rivers and the sea
The probe "Mars Express" conducted a probing greater part of the surface of Mars, after processing the received data, scientists have believed that Mars when in the past was heavy flooding is in the picture, the traces of water left with traces in the strata of sedimentary rocks. Besides flooding, this landscape is difficult to explain. First arrived a lot of water, and then the waters receded and left the furrows, gullies and alluvial Islands.
This was not for a hundred years, but at least the process lasted several hundred million years. Most of the channels and marks of water erosion, scientists have found in the valley of Kasei Valles, it is very big in length (3000 km) canyon in the Echus Chasma also, there are traces of water erosion. In order for Mars on the map to find Grand canyon Echo need to first find the plain Chryse Planitia, he is in Eastern direction from this place. Next, find highlands Tharsis from here draw a line to the East. Also find valley Marina and from it in a northerly direction to draw the line. Where will cross all three lines, that`s where you`ll see the canyon. First in the highlands of the Tharsis collapsed sedimentary rocks see the result of the rise in the level of groundwater, and then groundwater began to demolish in the direction of the canyon Echo. All this splendor in the past, scientists were able to photo review and analyze. Water canyon Echo was the breaker on and flooded the lowlands of the valley of Kasei. According to scientists, this event occurred about 3.6 billion years ago. It was not just a flood, but just a huge release to the water table. The flow of water in a matter of days have greatly changed the surface of Mars. In the valley of Casey, it`s not just the ancient track, it is the mark of a giant flood.
Water large flow went with high relief dots in the valley, on the way I saw the impact crater of Worcester, is a huge crater from a meteorite, its diameter is 25 km away. the Flow of water around the funnel and not damaged the sides of the pit. What is left in the pit and on the sides remained, and that was thrown out meteor crater was all washed into the valley by a strong stream of water. The images show that the crater now is not much like a crater, it`s more alluvial island or some sort of vague structure. Further, the slope of the alluvial layer is lined with a tiered structure of different sedimentary rocks, apparently at every stage of water movement is the formation steps of the sedimentary rocks. Each step is a separate episode in the heavy flood.
So much water was on Mars 3.6 billion years ago, over time, of water there was only ice caps at the poles, the rest of the water evaporated from the surface into space. If once was water on Mars and it was so much that was even the seas and lakes and all this water splendor lasted for centuries, that itself begs the question, where are the remains of former living creatures? Where the traces of those who dwelt on the slopes of these water lakes? Where are those residents who are in warm water lived? While none of what it finds, only some guesses and hypotheses täsch the minds of the fans to explore the desolate surface of distant Mars.
