Explanation:

Convection is the process of moving heat around by putting it into the molecules of a gas or liquid and then moving that hot gas or liquid to a new place where the heat can be released.

• Convection occurs naturally in our weather systems. If you sit by a large body of water on a sunny summer day you may notice later in the day a breeze coming off the water towards land (on-shore breeze). This is caused when the sun has had time to heat up the land, which in turn heats up the air in contact with it.
• This hot air expands and rises because it is less dense. As the warm air rises, the cooler air over the water rushes in to replace the warm rising air (the breeze you feel) and the warm air migrates up and over the lake, where it cools and settles down onto the lake. There you have a complete cycle of air flow that moves heat away from the land and spreads it out to cooler locations.
