Answer:

Convectional current

Explanation:

  • Convectional currents, as, you already know, occur due to density differences.

  • A more accurate definition of convectional currents will be transfer of fluid from one region the other.

  • Convectional currents imply degrees of hotness and coldness a fluid possesses. Thus, a fluid which is less dense will rise upwards and therefore is hotter and another fluid which is denser will go down and therefore is colder.

  • One use of convectional currents will be heaters. Heaters are placed at the bottom of a room so as hot air to be able to rise upwards and colder air to go down. Its reverse effect are air-conditioners.
