How to use in-sentence of “buoyancy”:
+ In physics, buoyancy is a force on an object making that object rise or move upward.
+ It is a central concept in floating vessels as it provides the buoyancy that keeps the vessel from sinking.
+ If the object has a higher average density than the liquid, then its buoyancy is less than its weight.
+ It is porous, full of small holes, The buoyancy of the cuttlebone can change, allowing the cuttlefish to go lower or higher by changing the amount of gas and liquid in its chambers.
+ If the object has a lower average density than the liquid, then its buoyancy is greater than its weight.
+ Archimedes’ principle: the weight of water displaced by an object equals the amount of buoyancy it gets.
+ Areas that are Rift rifting apart, such as mid-ocean ridges and the East African Rift have mountains due to thermal buoyancy caused by the hot mantle underneath them, which pushes them up.
+ Briefly: Buoyancy = weight of displaced fluid.
