Desert air usually has a very low moisture content. Air above a lake would be much more humid.
The air above a lake would generally have a higher humidity than air in a desert.
Yes, there can be fog in the desert. Parts of the Atacama Desert receive almost daily fog. Other deserts may have an occasional foggy morning following a rain when the humidity is high.
Generally, the air mass above the sea is more humid.
Yes there is water in the air above the desert but it is generally a low amount except during the rainy season.
Air in the desert is little different from air elsewhere. In the desert the air contains little water vapor and, in some cases, may be quite hot.
When the lenses are cooler than the surrounding air, the water vapor in the air may condense on the lenses, just as the water vapor in your breath condenses into steam when you exhale in very cold air.
There are a lot of different factors involved that vary from location to location, but one of the main reasons is that when air gets colder, it is not able to hold as much water vapor, so the water condenses into clouds. Temperatures are cooler at higher elevations, so when air moves from a low elevation (like a desert) to a high elevation (like a mountain) it is more likely to form clouds.
The illusion is a form of mirage. Light from the sun is reflected off of the very hot air just above the surface of the land and it appears to be reflecting off of water.
the bubbles in boiling water is water in a gasious state rising to the surface.
above the desert
Of course, water vapor will be higher, much higher, above a rain forest than a desert.
in a tropical rainforest
Water in a container consists of liquid in the container and water vapor above the container. As the air passes, it carries off the water vapor above the water and the water in the container replenishes it. Moving air blows water vapor away much faster than still air. As a result, a plate with water in it will dry faster if air is blowing on it than a plate will if no air is blowing on it.
Air in the desert is little different from air elsewhere. In the desert the air contains little water vapor and, in some cases, may be quite hot.
The tropical rain forest.
The warmer the temperature, the more water vapor the air can hold.
The air is very dry in the desert. Because the air is so dry, more of the sunshine reaches the surface. In other places where there is more water vapor in the air, the water vapor filters out more of the sunshine before it reaches the earth's surface.
rainforest
The amount of water vapor in the air varies considerably depending on climate and weather. In a desert water vapor may account for a tiny fraction of a percent of the air. In a tropical rainforest during a storm water vapor may account for as much as 4% of the air.
The air above the sea is more humid.
