GEOLOGY

Detailed explanation-1: -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-2: -Hawaiian volcanoes exemplify the common type of volcano called a shield volcano, built by countless outpourings of fluid lava flows that advance great distances from a central summit vent or group of vents.

Detailed explanation-3: -Mauna Kea and Mauna Loa are shield volcanoes. They are the world’s largest active volcanoes, rising over 9 km above the sea floor around the island of Hawai’i.

Detailed explanation-4: -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-5: -The Hawaiian Islands were formed by volcanic activity. The Hawaiian Emperor seamount chain is a well-known example of a large seamount and island chain created by hot-spot volcanism.
