Photo blog #5 Geology Photo Journal Project buoyancy/isostasy
Objective: Explain what the viewer is looking at in the picture, and how buoyancy/isostasy is involved. Is the object mostly submerged or mostly above the surface of the fluid? What does the level at which the object floats in the fluid tell us about the relative densities of the object and fluid?
THEM FROM ABOVE
In the two photos we see an assortment of objects in a tub of water. 3 of which are rubber ducks of my vast personal collection. In the middle is a plastic butterfly and to the right we see a rock that has been bisected and a paper crane that is slowly absorbing the water making it less stiff. I think these objects represent the idea of buoyancy/isostasy well as we have a range of those who float, those who float less and those who don't float at all.
The ducks, and the crane float wonderfully as by the ratio of them submerged vs what isn't submerged leans more on the non submerged side. The butterfly is almost entirely submerged but still floats a bit at the top. And lastly the rock is completely submerged with no signs of floatation anywhere. Those that float are less dense than the liquid it floats upon this being water. While those who sink are denser than the liquid it floats upon which is shown here to be the rock. The paper crane and ducks seem to be the least dense as they are the ones to be least submerged than say the butterfly. This is thanks to buoyancy which is the upward force the liquid exerts onto the objects.
