In a convection current, heat rises.
The convection current in the mantle drives the movement of tectonic plates.
Heat naturally rises in a room due to convection, where hot air is less dense and moves upward, while cooler air sinks.
When hot water cools down, the heat is transferred to the surrounding environment through a process called conduction or convection. Essentially, the heat energy dissipates into the air or any other material that the water is in contact with, causing the water to cool down.
As the suns rays hit the solar panel and heats up, the air or liquid heats up and becomes less dense so it rises, this now leaves the dense cool air to heat up which is lower since cool air doesn't rise. The sun heats up the cool air or liquid (usually solar panels are used to heat up hot water tanks) and this rises also, this has now made a 'convection current', the liquid will continue this convection current until its all at the same temperature. Solids do not go through convection current because the particles are closely packed and don't move because they have a definite shape.
A thermos reduces does not reduce heat transfer using convection, it reduces heat transfer BY convection. This is because there is a vacuum between the container of the liquid and the outer shell off the thermos. This means that no fluid will go round the inside conducting heat one way or the other.

Convection currents occur when heat from a source warms a fluid or gas causing it to expand and become less dense, thus rising. As it rises, it cools and becomes denser, causing it to sink back down in a continuous circular motion. This process creates a convection current.

When the eggs are cooking the eggs will heat up and go to the top of the pot then they will cool down and fall to the bottom of the pot then it will heat up again and go to the top and will keep going When the eggs are cooking the eggs will heat up and go to the top of the pot then they will cool down and fall to the bottom of the pot then it will heat up again and go to the top and will keep going
Convection I believe. If not conduction. I'd go with convection.
Actually, there are many ways for a convection current to form. So, if you asked this question, here is one way:A convection current forms when Hot air and Cold air form a cycle and mix. . .That's one way!ToodlesByee

The heat is released in the environmement by convection.
Warm air naturally goes up/rises and cold air has to make a current where it can go until it reaches a warm current which is under the warm air.
The air/liquid heats up causing it to rise at the top it cools down causing it to sink. At the bottom it rises again because it heated then it rises up causing it to sink because it has cooled down. The pattern will go until the heat is stopped.
