Water droplets form around microscopic foreign particles, called hygroscopic nuclei, that are already present in the air. These particles are in the form of dust, combustion residue (smoke and soot), salt from seawater evaporation and so forth. Because foreign particles initiate the formation of droplets that eventually fall as precipitation, condensation provides a mechanism for cleaning the atmosphere.
What else can I help you with?
Before clouds can form air must become?
Before clouds can form, air must become saturated with water vapor. This means that the air reaches its dew point, causing the water vapor to condense into tiny water droplets. These droplets then accumulate and form clouds in the sky.
In order for clouds to form what must be present in the atmosphere for water vapor to condense on?
In order for clouds to form, water vapor needs a surface to condense upon. This can be provided by tiny dust particles, salt particles, or other aerosols present in the atmosphere. These particles serve as nuclei around which water vapor can condense to form cloud droplets.
What are two things needed to form clouds?
Water vapour and heat. Wind is not necessarily needed to form clouds.
What are the 2 things that must be present for a wave to form?
The pressure from underneath the surface such as water volcano, underwater earthquake etc. or waves can be caused by strong winds blowing the water.
After cloud droplets form what must happen to them for precipitation to occur?
For precipitation to occur, cloud droplets must grow in size and become heavy enough to fall out of the cloud as precipitation. This can happen through processes such as collision and coalescence, where cloud droplets collide and merge together, or through the process of ice crystal formation when the cloud is cold enough. Once the droplets grow large enough, they will fall as rain, snow, sleet, or hail, depending on the atmospheric conditions.

What must be present so the clouds can form?
water vapour
What must be available for water vapor to condense and form clouds?
Water vapor must be present in the air, along with cooling temperatures or rising air currents, for the vapor to condense and form clouds. Condensation nuclei, such as dust or pollutants, also aid in cloud formation by providing surfaces for water vapor to gather and form droplets.
What must happen for precipitaion to form?
For precipitation to form, three main conditions must be met: 1) There must be enough moisture in the air in the form of water vapor, 2) the air must cool down, causing the water vapor to condense into liquid droplets (cloud formation), and 3) the droplets must grow in size and weight until they fall to the ground as precipitation (rain, snow, sleet, or hail).
What must be present so that clouds could form?
Water vapor and heat must be present for clouds to form. The water is evaporated from the ground and collected into a cloud.
Besides water vapor what must be present for clouds to form?
The Sun
What must happen before water vapor falls from clouds as rain?
Before water vapor falls from clouds as rain, it must first condense into water droplets. This condensation occurs when the water vapor in the air cools and reaches its dew point, at which point it forms visible clouds. Once the water droplets in the clouds combine and grow large enough, they fall to the ground as precipitation in the form of rain.
What must be present for any precipitation to occur?
cloud droplets or ice crystals must grow heavy enough to fall through the air.HOPE this has helped you :)Or by temperature dropping *i dont think thts 1*
What conditions must be present to frost to form?
water vapour/ cold /and a condensation medium
Which two substances must be present for an iron object to rust?
For the oxidation of iron to occur, that is for ferric oxide to form, there must be oxygen present. There must also be water present.
