Mars is made of rock and iron oxides. It's surface is covered in mountains, volcanoes, valleys, ice caps and dried up river beds. Mars is also very dry like a desert. It is also red because of the iron oxide in the pulverized rock dust.
Mars is a planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, deserts and polar ice caps of Earth.

Mars is a rocky planet that has a crust, mantle, and core. These are made up of different minerals and elements that include silicon, iron, and nickel. However, its atmosphere is comprised of about 96 percent carbon dioxide and other elements like nitrogen, argon, and carbon monoxide.

Most of the elements on Earth also exist on Mars, just in different proportions, quantities, and locations. Mars has a lot of iron compounds at the surface, which gives the planet a rusty, orange-red appearance.
