Is the Hawaiian islands an island arc?
Island arcs are formed by the subduction of an oceanic plate beneath another oceanic plate. The oceanic plate that is subducted beneath the other plate melts as it is pushed down into the mantle and creates a source of magma. The magma rises and forms volcanoes which create the islands of the island arc. The Hawaiian islands are formed by a mantle plume which is roughly in the center of the Pacific plate. The plate is moving across the plume and the islands are being formed in a line as the plate moves. The Hawaiian islands don't count as an island arc because they are formed in a completely different process and because they are roughly in a line, not an arc.

Thanks for the feedback!
it is a string of islands formed above a deep ocean trench
Many people are unaware that the big island is actually called Hawaii. It is the biggest of the Hawaiian Islands and Hilo is the island's main port.
CORRECTED: Aloha. Answer: There are primarily 7 Hawaiian Islands that comprise the State of Hawaii identified as follows:(01) Kauai (The Garden Isle) (02) Oahu (The Gatherin…g Place) (03) Maui (The Valley Isle) (04) Molokai (The Friendly Isle) (05) Lanai (The Pineapple Isle) (06) Hawaii (The Big Island) (07) Niihau (The Forbidden Isle) (08) Kahoolawe KAUAI "The Garden Isle" Kauai is a lush green island with long beaches and large gardens and is the oldest Hawaiian island in the tropical chain. OAHU "The Gathering Place" Home of world famous "Waikiki beach" and the state capitol Honolulu, Oahu is the most populated Hawaiian island, and also the most frequently visited. There are many historic military sites and of course many beautiful beaches and hotels. MAUI "The Valley Isle" In Maui there is plenty of nightlife to accompany the days pursuit of gorgeous beaches and huge volcanic craters. Is home to the world's tallest volcano "Haleakala Volcano" at some 10,000+ feet elevation. MOLOKAI "The Friendly Isle" Molokai is a small, quiet island with long, empty beaches. Home of Father Damiens (now Saint Damien) famous leper colony. LANAI "The Pineapple Island" Lanai is a very small and quiet island. Lanai is the ultimate hideaway and seclusive island good for relaxing. HAWAII "The Big Island" The Big Island is the newest and largest of the Hawaiian Islands. It boasts black, red and white sandy beaches; one of the most active volcanoes in the world (Kilauea); and 11 of the worlds 13 climate zones. It even snows at upper elevations here on the mountain tops. Niihau "The Forbidden Island" Unless invited you cannot stay on this tiny island. Kahoolawe A little island, minimally inhabited, off the coast of Maui. Hawaiian Island Chain Map:
Island arcs are formed from the subduction and melting of oceanic crust as it descends into the mantle underneath a less dense oceanic crust at a convergent plate boundary. T…he subduction results in the creation of undersea http://wiki.answers.com/Q/What_process_forms_island_arcs# which then rise above sea level. The resulting volcanoes create a string of islands called an island arc. The curve of an island arc echoes the curve of its deep-ocean trench.

and island arc is formed by undersea volcanoes. built over time, and island arc is made of basalt and melted rock from the mantle.
There are 8 "main" islands and over 100 other small islands or islets.
The State of Hawaii is composed of 132 islands, reefs and shoals that extend for over 1500 miles across the central North Pacific Ocean from the "Big Island" of Hawaii to Midw…ay and Kure Atolls.
There are the un-named, over 100 named island and eight "main" islands.

the british explorer captain james cook who 'discovered' Hawai'i (although you can't discover something that was already discovered), tried calling it that in an effort to 'ow…n' discovery of it. However, you can't rename a country that already has a name so Hawai'i remained Hawai'i. It is technically only referred to as the sandwich islands, not renamed that. captain cook tried naming Hawai'i the sandwich isles (islands) after his sponsor who was the earl of sandwich.
The island-arc volcanoes are formed from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.
