Explanation:

1. When two oceanic plates converge, one is sub - ducted beneath the other, often leading to volcanic island arcs and deep - sea trenches.
2. When two oceanic plates move away from each other, new oceanic crust is formed at mid - ocean ridges through seafloor spreading.
3. The movement of tectonic plates on Earth is driven by convection currents in the mantle. Hot material rises, cools, and then sinks, creating a cycle that moves the plates above.
4. Convection currents in the mantle involve hot material rising, spreading out laterally, cooling, and then sinking back down in a circular motion.
5. A hot spot is a place in the Earth's mantle where magma rises to the surface, creating volcanic activity that can form islands or volcanic mountains over time, regardless of plate boundaries.
6. When an oceanic plate collides with a continental plate, the denser oceanic plate is subducted beneath the continental plate. This can lead to mountain - building, volcanic activity, and the formation of deep - sea trenches.
7. A subduction zone is the area where one tectonic plate is forced beneath another, usually an oceanic plate beneath a continental or another oceanic plate. This zone is associated with earthquakes, volcanic activity, and the formation of trenches.
8. A trench is a long, narrow, and very deep depression in the ocean floor, typically formed at subduction zones where one plate is subducted beneath another.
9. A volcanic arc is a chain of volcanoes formed above a subduction zone, typically on the overriding plate. Magma rises from the subducted plate and erupts to form these volcanoes.
10. Island arcs are formed when two oceanic plates converge and one is subducted beneath the other. Magma from the subduction process rises and forms a chain of volcanic islands on the overriding plate.
11. The Himalayas are growing. They are formed by the collision of the Indian and Eurasian plates, and the continued northward movement of the Indian plate causes the mountains to rise.

Answer:

1. One oceanic plate is subducted beneath the other, forming volcanic island arcs and deep - sea trenches.
2. New oceanic crust is formed at mid - ocean ridges through seafloor spreading.
3. Convection currents in the mantle.
4. Hot material rises, spreads laterally, cools, and sinks in a circular motion.
5. A place in the mantle where magma rises to the surface resulting in volcanic activity.
6. The oceanic plate is subducted beneath the continental plate, leading to mountain - building, volcanic activity, and deep - sea trench formation.
7. The area where one tectonic plate is forced beneath another.
8. A long, narrow, and deep depression in the ocean floor, usually at a subduction zone.
9. A chain of volcanoes formed above a subduction zone on the overriding plate.
10. Formed when two oceanic plates converge and one is subducted, with magma rising to form a chain of volcanic islands on the overriding plate.
11. Growing.
