- (D) Shield volcanoes are built almost entirely of fluid lava flows in which
flow after flow pours out in all directions from a central summit vent, or
group of vents, building a broad, gently sloping cone with a flat, domed
shape. They are built up slowly by the accumulation of thousands of flows
of highly fluid basaltic lava that spread widely over great distances and then
cool as thin, gently dipping sheets. Examples of shield volcanoes include
those found in the Hawaiian Island chain, the Galapagos Islands, Iceland,
and East Africa.
