ASH PLUME
•
Erupting volcanoes release large amounts of ash in clouds.
•
Ash clouds released in eruptions that reach the stratosphere can span the globe carried by upper atmospheric winds.
These gases are produced during the heating of water by magma:
•
Water vapor (H2O)
•
Carbon dioxide (CO2)
•
Sulfur dioxide (SO2)
•
Hydrochloric acid (HCl)
•
Hydrogen fluoride (HF)
•
Hydrogen sulfide (H2S)
•
Carbon monoxide (CO)
•
Hydrogen gas (H2)
