What is negatively buoyant?

Negatively buoyant refers to an object or substance that has a greater density than the fluid it is immersed in, causing it to sink. This is in contrast to positively buoyant objects which have a lower density and float.

Negatively buoyant substances can be solids, liquids, or gases. Some common examples include lead, rocks, metals, and some types of plastics.

In aquatic environments, negatively buoyant organisms such as some species of fish and mollusks have adaptations that allow them to sink and remain on the ocean floor or other aquatic substrate.

In industries such as scuba diving and marine engineering, negatively buoyant materials are used to weigh down equipment and structures.

Overall, negatively buoyant substances tend to have greater mass and are more resistant to movement, making them less likely to be affected by strong currents or waves.
