Answer:

A shield volcano has shield-like shape. They are typically very large in area but their cones have a smoother, lower profile than composite volcanoes. They are shaped this way because their lava flows are made of basaltic magma, which has a lower viscosity than the lava from composite volcanoes.

Answer:

A shield volcano is a type of volcano usually composed almost entirely of fluid lava flows. It is named for its low profile, resembling a warrior's shield lying on the ground. This is caused by the highly fluid (low viscosity) lava erupted, which travels farther than lava erupted from a stratovolcano, and results in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form.

In volcanology, a lava dome is a circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Dome-building eruptions are common, particularly in convergent plate boundary settings. Around 6% of eruptions on earth are lava dome forming.
