Sometimes we have no clear horizon because a cloud is the surface level where we are. It's not a cloud, density, but is called "fog", which is a meteorological phenomenon, which is very low clouds at ground level and consist of small water particles in suspension.
Most fogs occur when soil moisture evaporation, which causes the ascent of moist air that condenses on cooling resulting in the formation of these clouds at surface levels. Fog leads to reduced visibility conditions at the surface.
Fog occurs mainly in a very damp and cold. Water droplets condense and form a cloud near ground level. When walking through the fog we see how water droplets are deposited on clothing.
Normally, the fog appears early in the mountains or at night because the sun tends to dissipate heat.
The fog is a relatively difficult to predict, since several factors influence training.
fog varieties can be classified by their training:

The fog is a relatively difficult to predict, since several factors influence training. fog varieties can be classified by their training:
- For precipitation: In the presence of a storm, or snow or rain, if it passes through an air mass whose temperature is higher than other same.
- On the ascent of air masses: When they are cooled and ascend, a common phenomenon in high mountain areas.
- For advection or towed The entry of a mass of cold air or warm in a territory, in parallel to a colder body, common in the oceans.
- For radiation: That only is located on the soil line, which starts during the night due to the cooling of the Earth by radiation from the Sun (the Earth is cooler than water), tends to disappear just dawning.
In short, the clouds are formed by condensation of moisture in the atmosphere. There is a scale that is used in meteorology to know when the water in the air will become visible in this figure is known as "dew point" and is shown as a temperature.
