because they do
The gas giants have no volcanoes; they are composed entirely or almost entirely of gas, so there is nothing to erupt. However, it should be noted that some of the satellites of the gas giants do have volcanoes.
All volcanoes are made of gas and magma.
Gas is what gives volcanoes most of their power. One of the reasons this happens is because the gas keeps expanding.
Volcanoes do not emit radiation as a primary feature of their activity. The main substances released by volcanoes are gases, ash, and lava. However, some volcanoes can emit low levels of radon gas, which is a radioactive element that occurs naturally in the Earth's crust.
No. Neptune is a gas planet with no solid surface. It cannot have volcanoes.
The amount of gas and the pressure in the volcanoes.
Volcanoes can produce lava, ash, and gas.
No, but its moon, Titan, may have volcanoes.
because of the heat in magma.
oxygen
Ash and Gas make composite volcanoes erupt i believe
Non-explosive volcanoes will have low concentrations of gas in the magma.
