There is an "Inca City" on Mars, and every time spring comes, countless black "spiders" appear near this "Inca City", what is going on?
How did these "spiders" come to be?
What is their geological significance?
1. The "spiders" on Mars.
There is a place on Mars known as "Inca City", a name given to some of the linear landforms found on satellite photographs taken by NASA's Global Investigator.
Located on a high ground near Mars' South Pole, the surface is covered with a thin layer of carbon dioxide ice that melts in the summer, revealing the soil beneath the surface.
On the surface of the soil, people have found a lot of "spiders", some of these "spiders" have a central point stretching out in all directions, and some have a central point stretching out in all directions, but they form small "branches" at the end of the extension.
The largest of these "spiders" is about 100 meters in diameter, and the smallest is only a few meters in size.
How did these "spiders" come about?
In the beginning, it was thought that these "spiders" had abundant water resources under the surface, and when summer came, the water under the surface would evaporate, along with some of the material on the soil surface, so that the soil surface would form a depression structure.
And when winter comes, these depressions are covered with ice, and when summer comes, these ice layers become melted faster than the surrounding soil, so that pores are formed, and when winter comes, these pores are covered by ice, and when summer comes, these ice layers become melted faster than the surrounding soil, so that pores are formed.
However, this explanation does not explain the very different shapes of these "spiders".
As people became more and more interested in these "spiders", people began to study these "spiders", and after studying the climate on Mars, it was found that these "spiders" have a lot to do with the climate on Mars.
On Mars, the temperature and pressure will change with the seasons, and when summer comes, the temperature on Mars will become hotter, so that the ice under the surface will melt, and the melted ice will carry some soil and rocks under the surface into the atmosphere, which will cause the air pressure in the atmosphere to rise.
However, when summer comes, the air pressure in the atmosphere will become relatively high, so that the ice under the surface will melt, and the melted ice will carry a piece of soil and rocks under the surface into the atmosphere, which will cause the air pressure in the atmosphere to rise.
When summer is over, the pressure in the atmosphere decreases with the arrival of winter, and this change in air pressure can have a great impact on the ice beneath the surface.
On Mars, the surface of the earth is covered with a layer of carbon dioxide ice, and this ice will gradually melt when summer comes, revealing the soil under the surface, and on the surface of the soil, people have found a lot of "spiders", these "spiders" are actually carbon dioxide gas eruptions, and this eruption will erupt with the change of air pressure, and these eruptions will form a linear landform on the surface.
2. The Martian "spider" is associated with the eruption of underground gases.
When summer comes, the temperature on Mars becomes hotter, so that the ice beneath the surface will melt, and the melted ice will carry some of the soil and rocks under the surface into the atmosphere, which will cause the pressure in the atmosphere to rise.
And when the air pressure increases, the ice under the surface will be compressed, resulting in the gas under the ice being squeezed, and when the air pressure is raised, the ice under the surface will be compressed, resulting in the gas under the ice being squeezed, and when the pressure of the extrusion is high enough, the carbon dioxide gas under the ice will be ejected from the surface.
When winter comes, the pressure in the atmosphere decreases with the arrival of winter, and this change in air pressure can have a great impact on the ice under the surface.
On Mars, the surface of the earth is covered with a layer of carbon dioxide ice, and this ice will gradually melt when summer comes, revealing the soil under the surface, and on the surface of the soil, people have found a lot of "spiders", these "spiders" are actually carbon dioxide gas eruptions, and this eruption will erupt with the change of air pressure, and these eruptions will form a linear landform on the surface.
And this explains why these "spiders" have such different shapes, which is caused by the different ways in which carbon dioxide gas erupts.
At the beginning, there are some hot places under the ice, these places will melt the ice first, and these places will form a kind of "spider" with the center point extending around, and when the "spider" stretches to a certain extent, it will form small "branches", and these "branches" are the eruption vents, and the number and size of the eruption vents will change with the intensity of the gas eruption.
The gas beneath the ice is squeezed, and when the pressure is high enough, the carbon dioxide gas beneath the ice is ejected from the surface.
And that's why some spiders have only one central point that stretches out in all directions, while others have a central point that stretches out in all directions, but at the end of the stretch they form small "branches".
These "spider" phenomena suggest that there may be abundant resources under Mars, and future exploration missions can focus on these areas.
epilogue
By studying the "spider" phenomenon on Mars, it may be possible to provide clues and explanations for the discovery of similar geological features on other planets in the future.
And what is the "Inca City"?
This "Inca city" may actually be an ancient crater, and its lines may have been formed by lava gushing out of the cracks created by the meteorite impact.
In the exploration of alien planets, geological processes can also have a profound impact on surface morphology, and we need to consider a variety of geological factors.
Seasonal changes in Mars have a significant impact on the Earth's surface landscape, and this gas eruption may also help us better understand the climate and geological changes on Mars.
