What are the two major processes that produce water vapor?
Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. Under typical atmospheric conditions, water vapor is continuously generated by evaporation and removed by condensation.
What 2 processes add water to the atmosphere in the water cycle?
The atmosphere is full of water Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents.
How do you calculate water vapor content?
Relative humidity can be measured with a hygrometer (Fig. 2) or a psychrometer. Hygrometers designed for home use are often found mounted together with two other weather instruments, a thermometer to measure room air temperature and a barometer to measure air pressure.
How do you measure moisture in the atmosphere?
Measuring Moisture Measuring water vapor and its concentration in the atmosphere is crucial for us to understand severe weather potential. To estimate the amount of water vapor, meteorologists use an instrument called a hygrometer. There are different types of hygrometers.
Is the measure of water vapor present in gas?
However, much of the water suspended in the atmosphere is in the form of an invisible gas we call water vapor. A measure of the water vapor content of the air is called humidity. This ratio we call relative humidity and it is always expressed as a percentage.
Which is a process that increases the amount of water in the atmosphere?
Two main processes are involved in increasing the amount of water vapor in the atmosphere. These two processes are known as evaporation, and transpiration. Evaporation is generally defined as the process by which water turns from a liquid back into a vapor or gas .
What are two processes in the water cycle?
These two processes are known as evaporation, and transpiration. Evaporation is generally defined as the process by which water turns from a liquid back into a vapor or gas. This occurs due to heat energy from the sun heating up liquid water molecules in bodies of water, such as streams, rivers, lakes, and oceans,…
How does evaporation and transpiration affect the water cycle?
Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents. Cooler temperatures aloft allow the vapor to condense into clouds and strong winds move the clouds around the world until the water falls as precipitation to replenish the earthbound parts of the water cycle.
Why does liquid water go into the atmosphere?
