The elevation above the surface where a cloud first forms is called the . a. evaporation level b. level of free convection c. adiabatic zone d. condensation level

d. condensation level

Explanation:

Condensation level is the elevation above the surface where a cloud first forms when air get into it. Because at that region, it is said that the humidity of the air will have reached it peak, then condensation starts to set in. As we equally known that when condensation occurs, water vapor in the air presumably changes into liquid water. So, we can therefore conclude that the significance of the condensation level is to assist in formation of clouds.
