Express the answer of the following problem
Problem- Fog, a cloud on the ground, forms through condensation occasioned by several different environmental conditions. True clouds, on the other hand, always form from adiabatic cooling and we classify them on the basis of their form and height. It is in typical clouds that precipitation forms.
Part 1- Describe the underlying physical conditions and mechanism of each of the two main theories for the formation of precipitation.
I need help to express the underlying physical conditions.
