Question Q.7GS1GS2
Discuss the processes involved in volcanism. Highlight the major volcanic regions in the world and their associated tectonic settings.
Introduction
Volcanism refers to the combined process of eruptions and the associated extrusive and intrusive landforms.

Main Body
Processes of volcanism 1) Generation of internal heat that drives the hot plumes => radio activism. 2) Magmatic differentiation => separation of lighter and heavier elements. 3) Phreatic vapour formation => provides the thrust for eruption. 4) Lava Flow => lahars, mud flows etc. 5) Solidification and consolidation, either within the earth Plutonic or near the surface hypabyssal. Major volcanic regions & Tectonic settings
1Mid-Atlantic Ridge => divergent boundary that leads to basaltic fissure type eruption. 2) Circumpacific Ring of Fire => convergent plate boundary (O-C) => explosive, felsic, acidic lavas. 3) Mid-continental Belt => Alpines, Ural, Alpinines, Carpathains due to continent-continent convergence. 4) Intra-Plate volcanoes => due to thermal gradients.
