These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). Each of these four spheres can be further divided into sub-spheres
Both Australia and Fiji are located to the South of the Equator, and quite close to each other. Fiji is located more to the North than New Zealand, but it is, just like New Zealand, to the west of Australia, so the statement that Australia is to the West of Fiji is false!
I'm pretty sure the answer is D but it's been a while since I've studied this. 95% sure it's D though :)

Hi. "Tidal wave" suggests a wave associated with the ebbs and flows related to the relative positions of the earth, moon and sun. These rises and falls relative to mean sea level are periodic and easily predictable. But the enormous wave generated by an earthquake is probably even less easy to predict than an earthquake and of no regular (that is, periodic) recurrence that anyone knows of. But I think "tsunami" is not too bad a name for such earthquake-generated waves as tsunami does not suggest any strong link with the relative positions of the earth, moon and sun.
