Shield volcanoes form extensive fluid lava flow that erupts numerous times.
A+ Shield
Shield volcanoes form from extensive fluid lava flow that erupts numerous times. This type of volcano has a broad, gently sloping shape resembling a warrior's shield, with low viscosity lava that can travel long distances before cooling and solidifying. Famous examples include Mauna Loa in Hawaii and Paricutin in Mexico.
Of the common types of lava, basaltic lava is the most fluid. However, one volcano, Ol Doinyo Lengai in Africa erupts unique carbonatite lava, which is extremely fluid. This lava appears to be closer in viscosity to water than basaltic lava.

A shield volcano is a type of volcano usually built almost entirely of fluid lava flows. Shield volcanos usually come from highly fluid lava that erupts, which travels farther than lava erupted from stratovolcanos.

Shield volcanoes have fluid basaltic flows that are lower in silicates, making the lava very fluid without a tendency to form pyroclastics. Composite Cone volcanoes contain the highest percentage of silica content making the magma thicker with the greatest tendency to form pyroclastics and are the most dangerous volcanoes.
Massive gently sloping volcanoes built of successive basaltic lava flows are called shield volcanoes. Examples of shield volcanoes include Mauna Loa in Hawaii and Mount Etna in Italy. These volcanoes are characterized by their broad, low-profile shape and the relatively peaceful eruptions of fluid lava.
Shield volcanoes produce fluid basaltic lava due to their gently sloping sides and low viscosity magma. These eruptions tend to be non-explosive and create broad, flat volcanoes over time.
Shield volcanoes are large volcanoes that are built almost entirely of fluid. Lava flows gently and continuously out of the central volcanic vent or group of vents.
Shield volcanoes have low silica magma, which is more fluid and runny compared to magma with higher silica content. This low silica content contributes to the gentle, flowing eruptions characteristic of shield volcanoes.
