Mars is very different from Earth https://youtu.be/4GvoF5xLxJE. Surface temperatures average around 210 K during the day near the equator but can drop to 130 K at night, especially near the poles, due to Mars' thin atmosphere. This allows carbon dioxide (CO₂) to sublimate and deposit directly as "dry ice", a phenomenon primarily observed in polar regions.
This atmospheric behavior contrasts with Earth's meteorology, showing how planetary atmospheres vary depending on composition and solar distance. While Earth experiences water-vapor-based snowfall, Mars' CO₂-rich atmosphere produces solid CO₂ deposition instead.
A substance's molecular structure and intermolecular forces determine its freezing point. Water molecules form strong hydrogen bonds, giving it a freezing point of 273.15 K, whereas CO₂, with weaker van der Waals forces, sublimates at 194.7 K under standard atmospheric pressure but can deposit at higher pressures on Mars.
