Question

Describe and explain the global distribution of volcanoes

Answer 1

Answer:

The distribution of volcanoes on Earth can be understood through the plate tectonic paradigm. The vast majority of volcanoes occur in curvilinear belts that define tectonic plate boundaries. ... The intraplate volcanoes that result from these “hot spots” account for approximately 15 percent of volcanoes.

Answer 2

Answer:

==>Volcanoes occur at any location where the Earth's crust is broken allowing the magma within the Earth to escape. Volcanoes are commonly found at edges of tectonic plates. ... Near tectonic plate boundaries. The world's tectonic plates is where you find the distribution of major earthquakes and volcanoes

Explanation:

==>Volcanoes are not found at conservative plate boundaries. ... Most volcanoes are distributed along the plate boundary. An example of a highly active earthquake zone is the west coast of North America and South America Occasionally, volcanoes are found in the middle of plates (e.g. Hawaii). These are called hot spots.

==>The 'hotspot' theory is that there are fixed spots in the mantle where magma rises to the surface. As the crust moves over these fixed spots, volcanoes are created, eventually forming a chain of volcanoes.
