Answer:
a) Volcanic chains are associated with convergent boundaries because that is where two plates are colliding.
b) A volcanic chain is associated with a convergent boundary because the two plates are colliding with each other, which causes the molten rock to rise to the surface.
Step-by-step explanation:
a) Volcanic chains are associated with convergent boundaries because that is where two plates are colliding.
Volcanic chains are associated with convergent boundaries because they are formed when two plates collide. The force of the collision creates a lot of heat, which melts the rock and forms magma. The magma rises to the surface and forms a volcano.
b) A volcanic chain is associated with a convergent boundary because the two plates are colliding with each other, which causes the molten rock to rise to the surface.
Volcanoes are often found near convergent boundaries because they form where tectonic plates are moving towards each other. The plates push against each other and create a lot of pressure. This pressure can cause molten rock to break through the Earth's surface and form a volcano.
