The Process of Fog in the Mountains
The fog is actually like a cloud. As we walk through the fog, literally it can be said that we are 'piercing the clouds'. But the difference, the fog is on the surface of the earth, while the clouds are higher. While the process is formed is the same, that is from the evaporation of water on the surface of the earth.
So as we already know, the air around us contains water in the form of steam or gas. But, it turns out the warm air can accommodate more water vapor. Well, when cooled then the water vapor that was in the air will condense partly. In other words, it returns to its original state, which is in liquid form.
At certain times or places, such as the movement from night to morning, or on the slopes and mountaintops, the air will experience a change in temperature. So that the water vapor or gas will reach the saturation point and change back into water.
Of course at first this water is only a very light water points. That's why they can hover in the air.
Because of the large number, then these floating water points are able to interfere with our eyesight. They are then divided, some continue up and become clouds, while the heavier droplets of water will fall to the earth and adhere to the leaves, glass of the house, and other objects.
Fog attached to the objects around us this is then become the forerunner formed dew.
Or if the survivors hover in the air, as the sun begins to shine and the air becomes warm again, they will return to the form of steam or gas. And the mist was gone exposed to sunlight.
