What are the scars on the surface of Mars?

When we search for pictures about Mars on the Internet, we will see something similar to a scar on the surface of Mars. What happened? Now let's get to know each other.

This scar is actually a grand canyon, located in the eastern part of Tasis Plateau on Mars, which is the largest canyon in the solar system. Sailor's Canyon? . This canyon is our first Mars probe? Mariner 9? Yes, it made a great contribution to us at that time. It was a great discovery, so this canyon was named after this detector, Sailor Canyon.

We can imagine that Mars is so big. If it is just a general canyon, it is not surprising and invisible on the surface of Mars. We can see it so carefully with the naked eye that we can imagine its area. Indeed, this grand canyon is enough to subvert your understanding, and its total length has reached 4500 kilometers. What is this concept? It is the distance from new york to L.A. This width is actually measured at the widest place.

Is it amazing to read this data? It is no wonder that such a big canyon can be seen so clearly with the naked eye, and this scar on Mars has become the most representative geographical symbol of Mars. Then how did this canyon form?

According to the research of scientists, this canyon should have been formed 3.5 billion years ago. Due to the continuous eruption of Tarsis volcano in the western region, the lava of the volcano spewed out and flowed into Tarsis Mountain, which made the terrain here uplift continuously. In this process of continuous uplift, until there is a fracture, then there are faults and broken lines.

Scientists even found that the canyon was originally eroded by floods. They speculated that there should have been water on Mars before. Later, due to climate change and other reasons, the water in the canyon disappeared, but the canyon remained.
