The movement of water when ocean and fresh water meet is called Density currents.
Deep currents are the result of differences in water density caused by variations in temperature and salinity. These differences create a gradient in density which drives the movement of water at depth in the ocean. The movement of deep currents plays a crucial role in transporting heat, nutrients, and oxygen around the world's oceans.
convection
The movement of a plate is typically considered uneven because plates move at different rates and in different directions. This uneven movement is driven by factors such as tectonic forces and the varying densities of different parts of the Earth's crust.
because of thermohaline circulation which means the movement of watr due to different densities
The differing densities of water create a consistent movement between the various thermal layers. As water is cooled, it actually expands, so it rises, and as it is warmed it sinks.
