Question

Mars is a planet that shows climate change on a large scale. Although Mars' atmosphere used to be thick enough for water to run on the surface, today that water is either scarce or non-existent. The atmosphere is also too thin to easily support life as we know it, although life may have existed in the ancient past. The climate of Mars comes from a variety of factors, including its ice caps, water vapour and dust storms. At times, giant dust storms can blanket the entire planet and last for months, turning the sky hazy and red. Though Mars and Earth share the atmosphere with various mixture of gases, life on mars is difficult. What do you think are the factors contributed for existence of life on Earth and not on mars. Explain how atmosphere is useful for existing of life.
