I believe a pot of water that is being heated by a electric burner. This is because the warmer water moves to the top and the cooler water moves down to the bottom of the pot. This causes a circular motion. The next example of convection heat is a hot air ballon rising and falling in the atmosphere. A radiator is also because the hot air is drawn out the top and the cooler air is drawn to the bottom.

Explanation:

Convection is defined as  a process in which upon heating a fluid (liquid or gas) there occurs rising of hot (less dense) dense molecules and sinking of cold (more dense) molecules.

For example, when rice in a pot of water are moving then it means the convection current arises in water when radiator that emits warm air and draws in cool.

As a result, rice that has absorbed heat become light in weight and hence they will rise and cold (more dense) rise that have not absorbed heat yet will sink at the bottom.

Similarly, when a hot air balloon is rising and falling in the atmosphere then hot (less dense) gas molecules causes them to rise in the air whereas cold molecules (more dense) will cause it to fall in the atmosphere.

Therefore, we can conclude that out of the given options examples of convection currents are as follows.

  • rice moving in a pot of water that is being heated a radiator that emits warm air and draws in cool.
  • air a hot air balloon rising and falling in the atmosphere.

bixtya [17]
A cactus can survive in really dry, hot weather. They store water in their "trunk." Just think of where a cuctus lives. They live in a desert. A desert is dry, hot, and lots of sun. Cactus manage to survive in that enviroment.
