Shield volcanoes erupt in a flowing, non-explosive manner, the lava flowing for extremely long distances creating the gentle shield shaped form. Eruptions at shield volcanoes are only explosive if water somehow gets into the vent, otherwise they are characterized by low-explosive fountaining that forms cinder cones and spatter cones at the vent. In a shield volcano, 90% of the volcano is lava rather than pyroclastic material. Due to high magma supply rates, the lava is hot and changes very little after it is generated. A common product of hotspot volcanism, shield volcanoes can also be found along subduction-related volcanic arcs or all by themselves
Shield volcanoes usually erup by fountaining or extruding lava.
I think there would be a crack in the earths crust so the magma can come out.
Shield volcanoes are produced by runny lava. That's why they have sloping sides and are like giant shields on the ground. The runny lava can't build up easily.
Mild volcanic eruptions slowly spew out lava that spreads across the outside slowly thus causing the not steep shape of it.
A good example would be the Hawaiis.
Shield volcanoes produce a gentle or almost silent eruption which ejects viscous or slow-moving lava.
they poduce shield volcanoes like the hawiian islands
Shield volcanoes produce fast flowing lava. They erupt frequently, but eruptions are gentle because the lava is so thin and does not trap gas in the volcano.
Shield volcanoes produce low-silica lava.
No, shield volcanoes are characterized by lava with a low silica content. Consequently, the principal hazard of the volcano is the lava flow rather than the eruption itself.
shield, cinder cone, composite, and dome. They produce basaltic lava, rhyolite lava and andesite lava.

Pahoehoe is a type of basaltic lava flow. The kind of eruption that causes pahoehoe is a quiet volcanic eruption.
Shield volcanoes produce flows of mafic lava, also called basaltic lava, which has a lower viscosity and low silica content. Oceanic crust has the same composition and so it is fairly easy for shield volcanoes to form here. Continental crust has a higher silica content. As a result, many continent based volcanoes produce much more viscous lavas which produce stratovolcanoes rather than shield volcanoes.
Lava
Pyroclastic flows don't come from shield volcanoes. They come from cinder cone and sometimes composite volcanoes. Shield volcanoes only erupt runny lava.
Shield volcanoes have effusive eruptions. Effusive eruptions are a volcanic phenomenon; in some ways the opposite of explosive eruptions. An effusive eruption is characterized by an outpouring of low viscosity lava which has a fairly low volatile content. Usually, shield volcanoes have effusive eruptions.
If you are talking about underwater volcanoes, than i have a answer. So, when underwater volcanoes erupt it MIGHT be able to create a island like Hawaii. Hawaii was made because of an eruption underwater.
No. Caldera and shield volcanoes are quite different. Shield volcanoes usually undergo effusive eruptions, the least violent type and produce basaltic lava. Caldera forming volcanoes erupt explosively and are the most violent. They generally produce rhyolitic lava.
