Early in its life Mars wasn't all too different from Earth. Most volcanoes on Earth form through tectonic activity (movement of crustal plates over the mantle), especially subduction. When an oceanic and continental plate collide, it sends the denser oceanic plate down toward the mantle, causing pressure that melts the rock into magma, eventually resulting in a volcano on the surface. Presumably the same or similar kinds of processes led to the development of the volcanoes on Mars. When we see volcanoes on Mars, its safe to assume they may have formed where they did because of the movement of Mars' continental and oceanic plates while the planet still had an active core.

How were Mars' volcanoes formed?

Since Mars lacks plate tectonics, the volcanoes were probaly formed by hot spots. These are areas where extra hot mantle material wells up and collects beneath the crust where some of it melts and rises through the crust to form volcanoes.
