GEOLOGY

Detailed explanation-1: -Shield volcanoes often form along divergent plate boundaries. They also form at hotspots, like Hawaii. Shield volcano eruptions are non-explosive.

Detailed explanation-2: -The six eruption types are in order from least explosive to the most explosive; Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian. Notice how, as the eruptions become more violent, the cone shapes become more steeply constructed.

Detailed explanation-3: -Rift volcanoes. Rift volcanoes form when magma rises into the gap between diverging plates. They thus occur at or near actual plate boundaries.

Detailed explanation-4: -Plates rip apart at a divergent plate boundary, causing volcanic activity and shallow earthquakes; and. At a convergent plate boundary, one plate dives or “subducts” beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate.

Detailed explanation-5: -Shield volcanoes are found on divergent plate boundaries, where two plates move away from one another. Shield volcanoes have the following characteristics: Basaltic magma, which is high in temperature, very low on silica and with low gas content.
