Shield volcanoes are huge in size. They are built by many layers of liquid lava flows. Lava spills out of a central vent or collection of vents. A broad shaped, quietly sloping cone is formed. This is caused by the very liquid, basaltic lava which can't be piled up into steep mounds.
Shield volcanoes may be produced by hot spots which put down far away from the edges of tectonic plates. Shields also occur along the mid-oceanic ridge, where sea-floor spreading is in progress and the length of subduction related volcanic arcs.
The eruptions of shield volcanoes are characterized by low-explosivity lava-fountaining that forms cinder cones and spatter cones at the vent. Famous shield volcanoes can be establish for example in Hawaii (e.g. Mauna Loa and Kilauea).
