Shield volcano
A shield volcano is a type of volcano usually built almost entirely of fluid magmaflows. They are named for their large size and low profile, resembling a warrior's shield lying on the ground. This is caused by the highly fluid lava they erupt, which travels farther than lava erupted from stratovolcanoes. This results in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. Shield volcanoes contain low-viscosity magma, which gives them flowing mafic lava.
