Question

what is Streams of water that skim along the bottom of the ocean. Happens when a surface current becomes colder, saltier, heavier and therefore sinks.

Answer 1

This is known as a deep-water current or thermohaline circulation. It is driven by differences in temperature and salinity, which cause water to become denser and sink to the ocean floor, creating a current that flows along the bottom of the ocean. These deep-water currents play a crucial role in the global climate system by redistributing heat and regulating ocean circulation patterns.
