In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
When cool dense water sinks, it becomes more dense because the cooler temperature causes the water molecules to contract and become more tightly packed together. This increased density allows the water to sink below warmer, less dense water layers.

the higher air flow, and the temperatures drop.
Cool things always sink (because they are more dense) and hot things always rise (because they are less dense) in convection. It does not matter if it is rock, air, water, metal, wax, oil, etc., convection always works the same.
The cold dye did not immediately rise into the warm water because of the difference in temperature. Cold liquids are denser than warm liquids, causing the cold dye to stay at the bottom initially. As the dye warms up, it becomes less dense and starts to rise through the warm water.
Yes, when air loses heat, it becomes denser because the air molecules contract and move closer together. As a result, denser cool air sinks while warmer, less dense air rises. This movement of air based on density differences is a key factor in atmospheric circulation and weather patterns.
This process occurs in the troposphere, the lowest layer of the Earth's atmosphere where weather events take place. As warm air rises, it cools and releases moisture, leading to cloud formation and precipitation. Conversely, cooler air near the top of the troposphere becomes denser and sinks back towards the surface in a continuous cycle known as convection.
The blobs of wax in a lava lamp rise and fall because of differences in their densities. As the wax heats up, it becomes less dense and rises to the top. When it cools down, it becomes denser and sinks back down. This process creates the mesmerizing flowing effect in a lava lamp.
Cool rock material sinks in the mantle because it is denser than the surrounding warmer rock. As the mantle heats up, the rock becomes less dense and rises due to convection currents. This process creates a cycle where cooler, denser material sinks while warmer, less dense material rises, facilitating the movement of tectonic plates and driving geological activity.
Convection, hope this helps.

Cool dense air moves from land toward water at night due to differences in temperature between the land and water. As the land cools more quickly than the water, the air above the land becomes denser, creating a pressure gradient that causes the air to flow from land to water. This process is known as a land breeze.
