Select the correct text in the passage. the moving continents affect all subsystems on earth. which sentence identifies a potentially negative consequence of shifting continents? the supercontinent pangaea began to break up about 175 million years ago. [during this process, more coastline was exposed as the landmasses separated]. [the rearrangement and displacement of these huge landmasses resulted in the diversity of plants and animals we see on earth today]. [the movement of the plates sometimes leads to earthquakes and tsunamis]. however, over the long course of earth's history, their effects are usually minimal. in oceans, the plate movements usually lead to seafloor spreading. [seafloor spreading often results in the formation of underwater ranges of mountains].

The correct answer is - The movement of the plates sometimes leads to earthquakes and tsunamis.

The movement of the plates leads to lot of changes across the globe, and they might be positive or negative, though it depends from which point of view the things are seen.

On the boundaries of the plates, there's constant adjustment deep inside the crust because of their movement. Those adjustments cause parts inside the crust to break, crumble, producing a lot of force, transmitted as quick, strong vibrations, which we know as earthquakes.

The earthquakes can appear on land and in the sea/ocean. Both of them can be devastating and cause a lot of damage, be it human lives, destruction of plants, killing off animals, material damage. The ones in the seas'oceans, also lead to the formation of tsunami, which essentially is a huge, powerful, quick moving  waves that wipe out everything on their way.
