because of the heat in magma.
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.
because they do
The smelly gas that often accompanies active volcanoes is known as fumarole gas. This has the same odor as rotten egg.
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.
oxygen
Ash and Gas make composite volcanoes erupt i believe
Non-explosive volcanoes will have low concentrations of gas in the magma.
