What is the difference between latent heat and humidity ?
Soil surfaces heat the lower atmosphere in three ways. First, any material–including the soil surface–radiates energy at an energy depending on the material’s temperature. Terrestrial surfaces on Earth radiate invisible infrared radiation that is absorbed by carbon dioxide 6 in the air, heating the air. Second, there is sensible heating 2 of the air directly in contact with warm soil surfaces. Sensible heat is heat you can feel. Finally, water evaporating from the soil surface absorbs energy in a form called latent heat 2. When the water vapor 3 condenses in the upper atmosphere it releases this latent heat, heating the air. Latent heat is absorbed and released whenever a substance changes phase, as when water evaporates from liquid to vapor and condenses from vapor to liquid.
