GEOLOGY

Detailed explanation-1: -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-2: -Volcano World There are three main places where volcanoes originate: Hot spots, Divergent plate boundaries (such as rifts and mid-ocean ridges), and. Convergent plate boundaries (subduction zones)

Detailed explanation-3: -Volcanic eruptions produce three types of materials: gas, lava, and fragmented debris called tephra.

Detailed explanation-4: -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.”
