1. Volcanoes occur at places where plates move apart because the magma from below the Earth's surface is able to rise up and create volcanic activity at the surface.
2. Volcanoes occur at places where plates move together because the movement of the plates causes friction and heat, leading to melting of the mantle below the Earth's surface. This melted rock, or magma, can then erupt through volcanoes.
3.
A. The first volcanic eruption is located in Japan, and the second volcanic eruption is located in Italy.
B. There are volcanoes in these areas because they are located along tectonic plate boundaries where there is a lot of seismic activity.
C. One cause of the Japanese volcano could be the subduction of the Pacific Plate beneath the Philippine Plate, while one cause of the Italian volcano could be the collision of the Eurasian Plate and the African Plate.
