- 1.海底板块移动得离中部山脊越远,额外的热能给予板块的浮力就越大。
That extra thermal energy gives the ocean plates more buoyancy as they move farther away from the ridges.

As the new crust cools, it sinks under its own weight-a process called subsidence-so the seafloor should be deeper the farther it is from a mid-ocean ridge.
