Mars and Earth

We are going to look at an very interesting and important place today. It is called Mars which is not far away from the Earth. Mars is an interesting neighboring planet to Earth with a similar geological surface and landscape, such as the desert, covered with rocks. Although there has not yet been evidence for the existence of water yet, the trace of heavy gases has existed on Mars for billions of years. Traces of a great amount of water in icy form just like mountains have been found. There is not much atmosphere, but rare gases are still found. It is possibly because heavy gases do not evaporate within a low gravity. The low gravity on Mars indicates that there may be a thin layer of the atmosphere on Mars. Therefore, Mars might be the most ideal destination other than Earth.
