Final answer:
The information provided discusses the temperature conditions of Mars but does not include details about Saturn's average surface temperature, preventing a direct comparison. Mars has temperatures ranging from -135 °C to 30 °C near its equator, while Saturn, a gas giant with no solid surface, is known to have an upper atmosphere that is much colder, allowing us to infer that Mars is warmer.
Step-by-step explanation:
How does the average surface temperature on Mars compare to the average surface temperature on Saturn? Based on the provided information which discusses Martian temperatures but does not provide data for Saturn, we cannot make a direct comparison. The lack of related information about Saturn's average surface temperature prevents us from concluding whether Mars is warmer or cooler than Saturn. However, we know that Mars has a thin carbon dioxide atmosphere and temperatures generally below freezing, with extreme temperature variations near the equator, ranging from an average of -135 °C at night to 30 °C during the day.
In stark contrast, although not stated explicitly in the information provided, Saturn is a gas giant with no solid surface and its upper atmosphere has very low temperatures, much colder than Mars. Therefore, even though the information about Saturn's temperature is not provided directly, it can be inferred through general knowledge of planetary characteristics that Mars is significantly warmer compared to the freezing temperatures found in Saturn's upper atmosphere.
