Shield Volcanoes
Quick revise
When lava is runny and thin it can flow a long way before cooling and solidifying, this causes shield volcanoes to have gentle slopes and wide bases built almost entirely of low viscosity basaltic lava flows.
Shield volcanoes are the largest of the three types.
The eruptions are generally non explosive due to the low silica content and may last for years
Example: Mount Kilauea in Hawaii (USA), Galapagos Islands, Snake River Plain in Idaho, USA.
