Lithosphere and Atmosphere Interaction
Name: Arpan P.
I was just curious about how the geosphere ( Earth ) affects the atmosphere?
I want to teach science class about the affects they have on each other. We were talking
about the atmosphere and the question just popped up. I looked it up in the library but
could not find it. I am trying to look for the answer but can find a lot of information.
Here is some help on how the geosphere interacts with the atmosphere.
Volcanic eruptions on the earth's surface. One of many examples would be Laki Fissure in
Iceland erupted in June 1783, putting sufficient ash into the atmosphere that the following
winter was extremely cold in Europe. The summer of 1783 was bleak in Iceland, resulting
in famine and the loss of a fifth of its population and more than half of its sheep,
cattle, and horses. Since 1986 Kilaeua Volcano in Hawaii, near the island's southeast's
coast has been working almost nonstop producing lava and, as a byproduct, 1,000 tons of
sulfur dioxide (SO2) gas per day. This sulfurous gas quickly combines with water to form
sulfuric acid, which is hazardous to health and very corrosive to metallic components.
Above ground volcanos when they erupt can also release millions of tons of carbon dioxide
gas into the atmosphere suffocating human and animal life along with producing acidic
conditions in nearby lakes and streams.
The same above scenario holds true for underwater volcanic eruptions.
Also, from a heating standpoint, approximately 50 percent of the solar energy that strikes
the top of the atmosphere reaches Earth's surface and is absorbed. Earth releases the
absorbed radiation in the form of long-wave radiation. The atmospheric absorption of this
long-wave terrestrial radiation, primarily by water vapor and carbon dioxide, is
responsible for heating the atmosphere. I hope that this helps.
