The type of volcano characterized by low silica magma and relatively nonviolent eruptions is a shield volcano.

Here's why:

* Low Silica Magma: Shield volcanoes are formed from basaltic magma, which is low in silica. This makes the magma very fluid and runny.

* Nonviolent Eruptions: The fluidity of the magma allows gases to escape easily, preventing the buildup of pressure that leads to explosive eruptions. Instead, shield volcanoes erupt with gentle lava flows that spread out over a wide area.

Examples of Shield Volcanoes:

* Mauna Loa (Hawaii)

* Kilauea (Hawaii)

* Mount Etna (Italy)
