Vegetable oil has the density of .92 g/ml and honey has the density of 1.42 g/ml. which liquid will float?

If you are saying float in water, than it is vegetable oil, as it has a lower density, in other ways lighter than water, so it will float if it is poured onto water. Honey has a higher density than water and way higher density than vegetable oil, therefore being heavier and more dense it will go down to the bottom.

That result from subduction of oceanic plates beneath lighter continental plates. most of the earth's volcanoes are located around the pacific ring of fire because that the location of most of the earth's subduction zones.
