Study Notes
Shield Volcano Overview
- Shield volcanoes are characterized by their gentle, gradual slopes and broad, dome-like shape.
- They are formed primarily by the eruption of low-silica basaltic lava, which flows easily and accumulates in layers.
Lava Characteristics
- The lava associated with shield volcanoes is basaltic, containing low levels of silica, resulting in its fluidity during eruptions.
Formation Process
- Shield volcanoes develop through the buildup of multiple layers of erupted lava over time, creating a broad structure as each layer cools and solidifies.
Physical Features
- The typical slope of a shield volcano is gentle, contrasting with the steep slopes of stratovolcanoes.
Notable Examples
- Mauna Loa, located in Hawaii, is one of the most prominent examples of a shield volcano, illustrating the typical features and formation processes.
Magma Source
- Beneath the Earth's surface lies magma, which is the source of the lava that erupts from shield volcanoes.
Layer Composition
- Shield volcanoes are predominantly composed of layers of cooled lava, contributing to their overall shape and structure.
