Hint:
Convection currents, which are also known as density currents arise due to the change in density of a substance. Convection currents are most of the time used only for liquids. Convection currents are also responsible for the movement in earth plates, or also known as tectonic plates due to which earthquakes come.
Complete answer:
Convection currents are related to density and that is why they are also referred to as density currents.
Let’s take an example, while boiling the water the hot water rises up and the cold water moves towards the down side, this is because the cold water is denser than the hot water and due to this change in density convection current arises. We can see this phenomenon in the given figure below.
From this figure we can easily see that the change in density arises the convection currents. The convection currents have a tendency to move fluid or gas particles from one place to another.
Few examples for convection current are boiling of water, change in weather, currents in ocean, Campfires and many more. Even without noticing It we use this phenomenon every day. The hotness we feel while sitting near the campfire is due to the convection currents, so next time you are having a campfire keep this in mind.
Note:
The heat energy is often transferred by the method of convection by the difference occurring in temperature between the 2 parts of the fluid. thanks to this temperature difference, the recent fluids tend to rise, whereas cold fluids tend to sink. This creates a current within the fluid called Convection current.
