Mars is cold because it is farther from the sun than Earth is. The sun, not volcanoes, is the main source of heat for a planet such as Earth or Mars. An erupting volcano can make it very hot, but only over a relatively small area. Even then, it appears that the volcanoes on Mars have not erupted for millions of years.
