The Hawaiian islands were formed by volcanoes. Volcanoes have two methods of formation, convergence of tectonic plates at the edges of the plates, and hot spots under the middle of plates. The Hawaiian islands and others in that area were formed when magma from the mantle rose to Earth's surface through a certain spot in the middle of the plate (i.e., the Pacific Plate for the Hawaiian Islands). This hot spot is situated beneath the center of the plate, and the volcano above moves with the plate as it moves, but the hot spot stays in place. This causes the original volcano to become extinct when its move cuts it off from its magma source and an island is born. A new volcano will then form above the hot spot again. This process repeats as the plate moves and a string of volcanoes (and eventually, islands) will dot the surface of the plate as the movement continues away from the hot spot.
Basalt is found in the mid-ocean islands and surrounding regions of the Hawaiian Islands and Iceland, as found by samples of lava flows found in drill cores recovered by vessels of the Deep Sea Drilling Project.

No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
Indonesia is located between the Indian Ocean and the Pacific Ocean. The islands of Indonesia are located along the equator between Asia and Australia.

Volcanoes.
The Hawaiian Islands are formed by the ocean structures known as submarine volcanoes. They continue to build the Pacific islands.

The Hawaiian Islands were formed and are still being formed right now by volcanic activity.

The Pacific Ocean surrounds the Hawaiian Islands.
The Hawaiian Islands were formed by the movement of the tectonic plates under the ocean floor. When the plates shift magma is released, and land masses form.

The Galapagos Islands were formed around five million years ago when underwater volcanoes started to rise from the ocean floor, resulting in the formation of around 20 rocky islands and more than 40 islets.
