• It is too cold for liquid water to exist on Mars
• Scientists believe that there was once liquid
water on Mars
What would happen if a persontraveled to Mars?
• Immediately the person would die due to the extremely low pressure on Mars.
• A person could also freeze due to Mars’s low temperatures
Something Special?
Mars has the largest and most violent dust storms in the entire solar system. These storms
often have winds topping 125 mph. They can last for weeks and can cover the entire planet. They usually occur when Mars is closest to the
sun.
