Hey, for all you volcanologists out there... in our textbook it states
that three factors affect how thick a lava flow is: temperature, gas
content, and silica content. One of my 7th grade students asked if
anyone had ever tried dumping massive amounts of silica into the head of
a lava flow to slow down its progress... has anyone ever heard of this
being tried?
