The formation of the Hawaiian Islands is one example of ____
A
volcanic activity forming over a hot spot.
B
volcanoes forming along plate boundaries.
C
the Ring of Fire.
D
continental drift.
Explanation: 

Detailed explanation-1: -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. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed.

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: -Hawaiʻi’s main volcanoes are “shield” volcanoes, which produce lava flows that form gently sloping, shield-like mountains.

Detailed explanation-4: -Volcanoes. Over its 85 million year history, the Hawaii hotspot has created at least 129 volcanoes, more than 123 of which are extinct volcanoes, seamounts, and atolls, four of which are active volcanoes, and two of which are dormant volcanoes.

Detailed explanation-5: -The formation of the Hawaiian Islands is an example of hot spots. A hot spot is a concentration of heat in the mantle capable of producing magma, which rises to the Earth’s surface.
