This spreads easily and cools to form the volcanoes’ sides. As the lava is so runny it can flow easily meaning that it does not build up to form a ...

The problem is complex, for volcanoes can help cool the earth's surface by forming sulfuric acid aerosols that reflect the sun's rays, and also contribute to global warming by giving off carbon dioxide into the atmosphere, which contributes to the greenhouse effect.

Lastarria
Lastarria, also known as Azufre, is a stratovolcano along the border of Argentina (border of the Catamarca and Salta provinces) and Chile (Antofagasta region). The volcano is part of the Lazufre volcanic system and is noted for the presence of molten sulfur lava flows as well as a debris avalanche. There is no recorded activity in historical times, but ground inflation has been observed.
