sulfur
A gas mask, but you probably shouldn't be there in the first place if it was a high concentration of these gases.
There are more than three gases that are found in solution in the ocean. The three that occur in highest concentration are oxygen, hydrogen and carbon dioxide.
the volcanic seven summits ?
pyroclastic flow
There are currently no uses for volcanic gases economically, but a sampling of the gases could be used in monotoring volcanic activity.
yes
Yes because volcanic gases release a gas that is harmful and basically started air pollution.
The highest concentration is in atmosphere. It is not on crust.
The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.
Diffusion- the random motion of gases moving from a higher concentration to a lower concentration.
Many Volcanic Mountains are considered Highest in this World.Most probably the highest volcanic mountain is Ojos de Salado in Peru, at 6891 metres, and erupted last about 1300 years ago.
