Answer: Eurasian/Pacific
Explanation: A "convergent plate" is one in which the Pacific and Eurasian plates move in the same direction. Subduction, in which one plate is typically pushed beneath the other, occurs when two plates meet. The Pacific plate is subducting beneath the Eurasian plate at the boundary between the two plates. Magma is created when the Pacific plate melts and enters the Earth's mantle. As it ascends to the surface, this magma may one day detonate into a spring of gushing lava. Mountains like the Andes in South America and the Cascade Range in North America can form along the boundary due to repeated volcanic eruptions. Due to the subduction cycle between the Eurasian and Pacific plates, mountains and volcanoes are probably considered to be along this boundary.
