Answer 1

Seafloor spreading, Crust becomes molten rock, Crust is formed, all of them I think

Answer 2

seafloor spreading occurs. Denser plates slide under the lighter plates.

Step-by-step explanation:

The oceanic crust bends deep inside and forms deep ocean trenches. The crust here actually sinks into mantle under continental crust through the process called subduction which lasts for million of years. Subduction occurs due to oceanic crust being denser than continental crust.
