At high altitude the pressure is lower and these factors favors evaporation.
It is difficult for water to evaporate when humidity is high because of water saturation in the surrounding environment.
Gravity. If you have water in a high place, it tends to fall into a lower place.
Factors that can make water evaporate slower include lower temperatures, higher humidity levels in the air, reduced surface area exposed to the air, and the presence of a barrier or covering over the water surface.
All substances can evaporate. If custard were exposed to a vacuum, all the water would evaporate off, but the more solid parts may remain. Custard doesn't evaporate when heated because it burns at a lower temperature than it it evaporates, and a good chef never cooks custard high enough to burn anyway.
Under vacuum conditions, the pressure is lower, which reduces the boiling point of water. This allows water to evaporate at a lower temperature than under normal atmospheric conditions. The lower pressure decreases the need for high temperatures to overcome atmospheric pressure and facilitate evaporation.
At a high temperature the evaporation of water is easier.
Water can still evaporate when the humidity is high, but the rate of evaporation is slower compared to when the humidity is low. This is because the air already has a high water vapor content, making it more difficult for additional water molecules to escape into the atmosphere.
Water will evaporate faster in dry air compared to humid air. This is because dry air has lower moisture content, creating a bigger difference in water vapor pressure between the air and the water surface, which enhances the rate of evaporation.
Liquid water evaporates due to high temperature. Sun's energy help it to evaporate.
A waterfall is a steep fall of water from a high place on the earth's surface to a lower one. They are created when a river or stream flows over a vertical drop in the landscape.
A high temperature favors evaporation.
Water is evaporated at any temperature but a high temperature favors evaporation.
