Mars shares many landforms and weather patterns with Earth, including changing seasons, volcanoes, canyons, dust storms, dust devils and water ice. Another feature that Earth and Mars share is polar ice caps. These are among each planet's striking features, but the major difference is that Earth's polar ice caps are both composed of water, while Mars' north polar ice cap is composed only of water and its southern polar ice cap is carbon dioxide.
