Answer to Question 1

Most volcanoes are at or near convergent or divergent plate boundaries. The two major volcano belts
are the circum-Pacific and the Mediterranean; the rest are near the mid-oceanic ridges

Answer to Question 2

Composite volcanoes are formed of lava flows and pyroclastic layers. The eruptions are intermediate
in composition, and because they are more viscous than other eruption types, the sides of the
volcanoes tend to be steeper, especially near the top. These eruptions are more explosive than shield
volcanoes and larger than cinder cones and so may cause more damage
