Volcanoes form igneous rock.
The Hawaiian Islands are volcanic in origin. Each island is made up of at least one primary volcano, although many islands are composites of more than one. The Big Island, for instance, is constructed of 5 major volcanoes: Kilauea, Mauna Loa, Mauna Kea, Hualalai and Kohala. Mauna Loa is the largest active volcano on Earth. Kilauea is presently one of the most productive volcanoes on Earth (in terms of how much lava it erupts each year). 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. When molten, basalt produces liquids of relatively high fluidity, compared to volcanoes that erupt more silica rich magma types such as andesite, dacite or rhyolite. The fluidity of molten basalt favors the formation of lava flows, which is why the Hawaiian volcanoes generally have gentle sloping sides. By contrast, lavas with higher silica content are more viscous and commonly produce either thicker, shorter lava flows, thick blocky deposits and/or thick beds of ash that fall from the sky following explosive eruptions. These other types of volcanoes (common outside of Hawaii) are typically steeper sided. The Hawaiian volcanoes were produced by the Hawaiian hot spot, which is presently under the Big Island of Hawaii. The image below shows the islands of the Hawaiian chain and the intervening shallows, banks and reefs along a line from southeast to northwest. Note that the islands of Lanai and Kahoolawe are not shown because they would "overlap" with Molokai and Maui, respectively (see the map of the Islands on the Hawaiian Volcanoes page) In general, when you move along the island chain from southeast (Hawaii) to northwest, (Kure), the volcanoes become older and older.

High islands, especially ones with volcanoes, usually contain fertile soil.

Shield volcanoes
The Hawaiian islands are made of two types of volcanoes, shield volcanoes and cinder cone volcanoes. Shield volcanoes have broad bases with gentle slopes. Cinder cone volcanoes have steeper sides, are made from fragments of lava, and are usually located at the base of shield volcanoes.
the type of lava
Stratovolcanoes, shield volcanoes, and complex volcanoes have all formed islands.

All of the active and inactive volcanoes that are part of the Hawaiian-Emperor Seamount chain are shield volcanoes. Shield volcanoes are the result of Hot Spot volcanism which is the type of volcanic force that created the Hawaiian islands.
The Hawaiian volcanoes can form cinder cones, however the type of volcano they are classified as is shield volcano due to their broad sloping sides and the ability for their lava to flow.No. The Hawaiian islands are shield volcanoes.
Kaho'olawe is uninhabitable because the U.S. Military used it as a bombing range. True, most people would think it was from a volcano, but it was from the Military.
