When they blow off you can spot them with a telescope.
you can only find volcanoes on the inner planets: that are Venus, mercury and mars
There are many planets that have volcanoes and canyons. The Earth is a wonderful example of a planet with both.
there are no volcanoes in outer plants.
Yes!
Earth, Venus and Mars all have volcanoes.
Yes there is.
Yes.
Venus, Earth, and Mars are all planets with volcanoes.
Earth...
It is impossible for the jovian planets to have volcanoes, because they are made of gas.
The planets other than Earth on which we have observed volcanoes are Venus and Mars. These planets are made of the same materials to Earth and formed by the same processes. Therefore, like Earth, they have hot interiors that can produce molten rock. Mars may have cooled enough that the volcanoes it has no longer erupt.
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.
