Detailed explanation-1: -Sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”
Detailed explanation-2: -Magma rises from the hot spots and erupts as lava through cracks in the Earth’s surface forming volcanoes. As a plate moves slowly across a hot spot, a chain of volcanoes or volcanic islands can form. The islands of Hawaii and Samoa were formed in this way.
Detailed explanation-3: -There are volcanoes on every continent, even Antarctica. Some 1, 500 volcanoes are still considered potentially active around the world today; 161 of those-over 10 percent-sit within the boundaries of the United States.
Detailed explanation-4: -Hot spots, Divergent plate boundaries (such as rifts and mid-ocean ridges), and. Convergent plate boundaries (subduction zones) 24-May-2010
