Question
1. does Earth have oceans, as opposed to the water being evenly distributed everywhere?
It is fashionable. C'mon, who wants a swampy, marshy Earth everywhere? Nobody does.
-The denser oceanic crust+lithosphere system sinks deeper, and water collects in the depressions
The oceans push down on oceanic plates, and hence water collects in the depressions
Continents are denser, and hence push continental lithosphere deeper, and oceans go elsewhere.
-Sea water is part of the convection cycle, and hence fluids are produced at mid-ocean ridges

Explanation / Answer
Earth has oceans, as opposed to the water being evenly distributed everywhere the oceanic crust is not smooth i.e of same smoothness some parts are more depressed due to the subduction involved while some parts are elevated due to the oceanic island arcs and gyouts ."the denser oceanic crust+lithosphere system sinks deeper, and water collects in the depressions" the area discussed here is the trench part which is deep like Mariana Trench. option 5 is wrong as sea water is not fully involved in the convection cycle it is the molecular water present in the mineral-like hornblende that is involved in the convection, not the sea water
