What are the two types of buoyancy that divers experience?

Positive buoyancy and negative buoyancy are the two primary types of buoyancy that divers experience. Positive buoyancy occurs when an object or diver is less dense than the surrounding water, causing it to rise or float to the surface. This is commonly experienced when a diver is using a flotation device or has not adequately compensated for the weight of their scuba gear, leading them to ascend without actively swimming upward.

Negative buoyancy, on the other hand, takes place when an object or diver is denser than the surrounding water, resulting in sinking or descending. This condition is often managed by the diver using their weight system to control their depth more effectively.

Neutral buoyancy is a desirable state in diving where the diver neither sinks nor floats but remains at a specific depth, typically achieved by balancing the weight of the diver's equipment with the buoyancy of the water. However, since the question specifically addresses the two main types of buoyancy that divers experience, focusing on positive and negative buoyancy captures the complete essence of buoyancy dynamics in diving.

In contrast, terms like stable buoyancy are not standard classifications within the context of diving, as they don't describe specific buoyancy states but rather refer to a more nuanced experience while underwater, therefore they don't fit as
