INDIAN GEOGRAPHY

Detailed explanation-1: -Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, at what is called a “hot spot.” The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving.

Detailed explanation-2: -The Hawaiian Islands were formed by a volcanic hot spot, an upwelling plume of magma, that creates new islands as the Pacific Plate moves over it.

Detailed explanation-3: -Hot spots are found in the ocean, and on continents. Often the hot spot creates a chain of volcanoes, as a plate moves across a relatively stationary mantle plume. The best example of a hot spot volcanic chain is the Hawaiian Islands.

Detailed explanation-4: -The Hawaiian Islands are all classified as shield volcanoes. Hawaiian shield volcanoes are formed by lava flowing on the ocean floor and building layer upon layer into great volcanoes. The hot spot theory explains that magma from the upper mantle rises through a channel into a magma chamber called a hot spot.
