Question

14. Which type of heat transfer (caused by uneven heating) moves air and water around the earth and creates weather? Question 14 options: convection conduction radiation none of the above

Answer 1

Answer: convection

Explanation:

There are three ways in which the heat (thermal energy) transfer occurs:  

1. By Conduction, when the transmission is by the direct contact.  

2. By Convection, heat transfer in fluids (like water or the air, for example).  

3. By Radiation, by the electromagnetic waves (they can travel through any medium and in vacumm)

In this especific case, we will talk about convection, which occurs when the hottest parts of a fluid ascend to the coldest zones, generating a continuous circulation of the fluid (better known as convective current) transmitting heat to the cold zones by decreasing the density caused by the increase in temperature.

This is what happens in Earth, when the convective heat transfer occurs, through the movement of groups of molecules that make up the medium (water and air in this situation) changing with temperature and creating the weather .
