Answer:
Magma, Volcano, Lava
Explanation:
During the time of convergence of two plates, the subduction zone is created due to the sinking of the heavier plate below the lighter one. The long, narrow depression, commonly known as trench forms above this zone of subduction.
As the heavier plate goes down, it melts and mixes with the magma. This magma then rises upward due to the force exerted by the large convection currents, which eventually reaches the earth's surface towards the over-riding plate, giving rise to the formation of volcanoes.
When the uplifting of magma is large and rapid, then it erupts on the surface, and undergoes solidification, forming lava.
Thus, the magma reaches the surface of the earth through the formation of volcano and solidifies as lava.
