For the atmosphere part of the question, there are differences in the composition of the air (both the elements that are present and their relative percentages), the amount of gas in the atmosphere (the air pressure), the temperature (it is much colder on Mars), and different weather patterns (for example, there is no rain on Mars). For the surface part of the question, there are differences in the composition of the soil and rocks (the presence of red, oxidized iron is notable on Mars), the more obvious craters on Mars, much more volcanism on Mars (note Olympus Mons), the absence of liquid water on Mars, more dunes on Mars than on Earth, the size and composition of polar ice caps (carbon dioxide ice over water ice on Mars), and the absence of plants and animals on Mars. Wind is the main cause of erosion on Mars - there are more dust storms on Mars than there are on Earth (on Earth, water is the major cause of erosion). (There are a lot more differences, but these are the most obvious ones.)

Mars have lots of carbon dioxide.
