When a material becomes hot enough, it rises because it less dense.

In the Mediterranean Sea the cool dense water sinks under less dense water which is called density current.
Because the paperclip is not dense enough to break the surface tension of the water
When air loses its heat it actually becomes more dense and sinks which starts a convection current
When it is heated it becomes less dense (i.e. lighter). The more dense (i.e. heavier) magma sinks while the less dense magma rises to the top. It will eventually cool again causing a convection current within the mantle.
A convection current is a cycle. The way the cycle works is when the liquid is heated the particles become less dense as it rises to the top and then it becomes more dense so it comes back down again. Then the process starts again.
well to be 100% honest, a surface current is basically a current on the surface. This particular current moves in a stream-like fashion on the surface of the ocean. A surface current can be short, wide, deep, or narrow.
Fluids rise and sink in a convection current due to differences in temperature and density. When a fluid is heated, it becomes less dense and rises, creating an upward flow. As it cools, it becomes more dense and sinks, creating a downward flow. This continuous cycle of heating and cooling drives the convection current.
Temperature affects air pressure because as air warms up, it expands and becomes less dense, causing it to rise. This leads to lower air pressure at the surface. Conversely, as air cools, it contracts and becomes more dense, causing it to sink and creating higher air pressure at the surface.
