Volcanoes in the
Solar System

Volcanic eruptions are perhaps the most dramatic events that occur on Earth. Terrestrial volcanoes are important to understand not only as potential hazards, but also as geologic resources, biologic environments, and for their role in shaping the surface of Earth and other planets. Volcanic activity has been significant in shaping the surface of the rocky planets in the inner solar system (Mercury, Venus, Earth, Mars), and in some of the moons in the outer solar system as well. In fact, Jupiter's rocky moon Io is the most volcanically active body in the solar system. Volcanoes are not limited to rocky objects, however. Two of Jupiter's icy moons, Europa and Ganymede, as well as other icy moons in the outer solar system, have features scientists believe were produced by ice volcanism. Whether occuring in ice or rock, volcanic activity involves heat, a form of energy that is important in biologic environments on the earth, and perhaps for environments on other planets in the solar system as well. Join us to learn about the types of volcanoes on Earth as well as other planets in the solar system.
