What impact does volcanic gas have on the environment and people?

Kilauea, on the island of Hawaii, may be the world’s most active volcano. As long as the history of this eruptive
peak has been documented, it’s been sending rivers of molten rock cascading across the landscape, and
spraying volcanic gas into the air. The most recent eruption was a months-long, but not severe, flow of lava
tubes this past spring and summer.

What exactly is volcanic gas?
Possible response:
Volcanic gas is comprised by the substances emitted from a volcanic
eruption, including water vapor, carbon dioxide and sulfur dioxide,
hydrogen, metal chlorides and carbon monoxide. Before an eruption the
gases are held within the molten rock of the mountain.

volcanic gas enters the air?".
Thinking
What are the parts of the process that seem to impact the
environment?
Possible response:
This image conveys how hydrogen chloride and hydrogen fluoride fall to
the ground as acid rain. Acid rain probably impacts the environment, and
probably in a negative way, given the substances it contains, which are
harmful to wildlife and possibly vegetation.
Things to consider: What parts of the process do you recognize from
your own life, or maybe things you've read about?

Find at least one example of the environmental impact of volcanic
gas. What impact does volcanic gas have?
Possible response:
Large eruptions cause the most damage to the environment globally.
These eruptions emit large amounts of sulfur dioxide, hydrogen fluoride
and carbon dioxide - the most dangerous substances to the earth. Sulfur
aerosols can contribute to the depletion of the ozone layer. While
hydrogen fluoride can be carried through acid rain and disrupt the
ecosystem. Carbon dioxide can collect in soil. One popular example of
this is the eruption of Mount Pinotubo in 1991, whose environmental
impact was investigated several times.

How do you think the example you presented impacts the lives of
people?
Possible response:
Man-made pollution also destroy the ozone-layer, so if volcanic eruptions
can exacerbate the ongoing effects of pollution and other processes that

Things to consider: Since global warming is effected by processes
impacting the air, how might volcanic gas influence global warming? What
are the impacts of global warming on people's lives?
