All of the terrestrial planets (Mercury, Venus, Earth and Mars) had volcanic activity at some time. Only the Earth has active volcanoes now. Mars has the largest volcano in the solar system at over 16 miles high - three times the height of Everest (Now extinct). IO, a moon of Jupiter is known to be volcanically active with over 400 volcanoes.
Differentiation occurred in other inner planets, besides Earth.
It's impossible to answer this question. We don't even know how many volcanoes there are in the solar system. I'm not sure we know exactly how many volcanoes there are on Earth.
Mars and Venus both have volcanoes and canyons. Mars is home to Olympus Mons, the largest volcano in the solar system, and Valles Marineris, one of the largest canyons. Venus has numerous volcanic features and canyons, such as Maxwell Montes and the rift zones of Ganis Chasma.
Liquid water. All else is incidental.
Neither of them have rings, and they also have impact crates from collisions of the planets with objects primarily made of rock 2nd Answer: Also the Terran (Earthlike) planets are rocky while the Jovian planets are mainly composed of different gases.
Earth, Venus and Mars all have volcanoes.
Earth...
Venus, Earth, and Mars are all planets with volcanoes.
Most volcanoes on Earth are associated with boundaries of tectonic plates while those that we have seen on other planets are probably from hot spots. Earth's volcanoes also seem more prone to explosive eruptions, primarily due to the abundance of water on Earth.
Yes, Venus.
none
