Expert Answer:

At any depth in air there is an upward force due to the effect of gravity on the air. If the density of an object in air is greater than the density of the air, the object will sink. This is because weight of the object is more than the buoyancy from the air. If the density is less than that of the air, the object will float upward due to greater buoyancy from the air.
