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.
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.
"Convection" is the word used to describe the movement of heat from one place to another in onevery specific way ... the physical movement of heated material.Any material typically has a lower density than the same material has when it's cool, and and we knowthat less dense material floats in material that is more dense. So warm floats on top of cool (think of the"hot-air" balloon), and the convection process consists of these steps:-- Heat is applied to the bottom of a pool of material. The bottom layer becomes warm, and its density decreases.-- The less dense material floats to the top of the pool. Cooler, more-dense material sinks into its place.-- The cooler material is warmed by the heat source at the bottom, becomes less dense, and the wholeprocess keeps repeating.This is the process of heating a kettle or saucepan of water on the stove, and it's the reason thatthe burners are UNDER the pot ... The heat must be applied to the water at the bottom. Whenthat water becomes warm, it floats to the top, and cold water sinks into its place. The water in the potis heating by the process of convection.It's also the reason that the warm-air vents or the baseboard heaters in a house are at the bottom ofthe room. If the warm air entered at the top of the room, it would just sit there, floating on top of thecool, more-dense air, and the room would not want to heat. By inserting the warm air into the roomat floor-level, the warm, less-dense air floats to the top, and cool, more-dense air sinks to the floor, totake its place and be warmed. The air in the room is also heated by the process of convection.
