How Science Works - Journey to Etna: Lava Flow and Gas Emissions

Description

Aimed at GCSE science classes, this short video looks at volcanic emissions and lava flow.

Following a team of volcanologists at Mount Etna, they show us they way in which lava cools to form igneous rock.

Depending on the mineral composition of the lava, it will cool and form two distinctive structures, known as aa and pahoehoe.

They also explain how volcanoes also emit huge amounts of gases when they erupt, such as Carbon Dioxide, Sulphur Dioxide and even Gold, which can significantly alter the earth's atmosphere for years.
