GEOLOGY

Detailed explanation-1: -Volcanoes can also form above a column of superheated magma called a mantle plume. This may happen in areas that are distant from plate boundaries. It is also referred to as hot spot or intraplate volcanism.

Detailed explanation-2: -Volcanoes can also form at places called hot spots. Hot spots are magma chambers that form at places other than plate boundaries. They can even form in the middle of tectonic plates. The islands of Hawaii were formed from volcanoes that developed at a hot spot.

Detailed explanation-3: -Tectonic activity such as earthquakes, volcanic eruptions and the formation of mountain ranges commonly occurs along the boundaries of the moving plates.

Detailed explanation-4: -At transform plate boundaries, the two plates slide by each other. This generates little volcanic activity (there is no “gap” between the plates) or mountain building. Earthquakes, however, are common. Much magma is generated at a converging plate boundary where subduction is occurring.
