Answer:
1. One oceanic plates is eventually subducted under the
other
2. As plate A continues to move downwards going to the mantle. The leading edge of plate A will melt and turns into magma
3. because of two plates leading to subduction
4.a subduction zone is also generated when 2 oceanic plates collide, And it leads to the information of chains of volcanic islands known as island arcs
