GEOLOGY

Detailed explanation-1: -Shield volcanoes are found worldwide. They can form over hotspots (points where magma from below the surface wells up), such as the Hawaiian–Emperor seamount chain and the Galápagos Islands, or over more conventional rift zones, such as the Icelandic shields and the shield volcanoes of East Africa.

Detailed explanation-2: -The primary volcanoes on each of the islands are known as a shield volcanoes, which are gently sloping mountains produced from a large number of generally very fluid lava flows. Hawaiian volcanoes primarily erupt a type of rock known as basalt.

Detailed explanation-3: -Hawaiʻi’s main volcanoes are “shield” volcanoes, which produce lava flows that form gently sloping, shield-like mountains. A good example is Maunaloa, the most massive mountain on earth, deceptively covering half of Hawaiʻi Island.

Detailed explanation-4: -Shield volcanoes They are built up slowly by the accretion of thousands of highly fluid lava flows called basalt lava that spread widely over great distances, and then cool as thin, gently dipping sheets.
