This is the end of our Exploratour comparing the surfaces of Earth and
Mars. We have shown you maps of the planets' surfaces, continents,
cratered terrain, volcanoes, rocks and soils, water features, and the
polar caps. We
hoped you enjoyed this Exploratour. For more information about Mars,

reach a full range of information, including science, space missions, facts,
