How was the city of cydonia made?

Cydonia is a region on Mars known for its unique geological formations, including the famous "Face on Mars." It was formed through a combination of volcanic activity, erosion by wind and possibly water, and the planet's tectonic processes over millions of years. The region's distinct features are primarily shaped by Mars' arid environment and lack of significant atmospheric weathering compared to Earth. The interpretation of specific formations, like the Face, often involves a mix of natural geological processes and optical illusions.
