Small particles of dust or smoke in the air that water vapor attaches to in order to form clouds and precipitation?
Cloud condensation nuclei are tiny particles in the atmosphere around which water vapor can condense to form clouds. These particles can come from a variety of sources, such as dust, smoke, pollution, or sea salt. When water vapor condenses on these nuclei, it forms cloud droplets or ice crystals that eventually grow into clouds and precipitation.

Which is true about water droplets in clouds?
Water droplets in clouds are small liquid particles that form when water vapor in the air condenses around tiny particles called cloud condensation nuclei. These droplets can collide and combine to form larger droplets, eventually leading to precipitation. The size of the water droplets in clouds determines whether they remain suspended in the cloud or fall as rain.
What causes a drizzle?
Drizzle is caused by very small water droplets in the atmosphere that are small enough to remain suspended. It typically occurs in light precipitation and tends to fall slowly and steadily from low-lying stratus clouds.
What atmospheric conditions contribute to the phenomenon of pink clouds?
Pink clouds are often caused by the scattering of sunlight by small water droplets or ice crystals in the atmosphere during sunrise or sunset. This scattering effect is more pronounced when the atmosphere contains a higher concentration of particles, such as dust or pollution, which can enhance the pink color of the clouds.
What occurs when light waves travling through the air reflect off small particles?
When light waves traveling through the air reflect off small particles, it results in a phenomenon known as scattering. The scattering of light causes the particles to become visible as they redirect light in various directions, creating effects like the blue color of the sky or the white appearance of clouds.
Compare coalescence and supercooling?
Coalescence is the process by which small water droplets in a cloud combine to form larger droplets, which eventually fall as precipitation. Supercooling refers to the phenomenon where a liquid is cooled below its freezing point without actually turning into a solid, usually due to a lack of nucleation sites. Both coalescence and supercooling are important processes in the formation of precipitation in clouds.
Is it true that radar signals will pick up precipitation but not clouds?
Radar signals can detect both precipitation and clouds, but they respond differently to each. Radar detects precipitation by bouncing signals off water droplets or ice particles in the air, whereas clouds are made up of tiny water droplets or ice crystals that are too small to reflect radar signals effectively. So, while radar can show the location and intensity of precipitation, it may not provide a detailed view of clouds unless they contain significant amounts of precipitation.
What is a method to modify precipitation by dropping tiny crystals into clouds?
The method you are referring to is called cloud seeding. It involves dispersing small particles, such as silver iodide or salt, into clouds to encourage water droplet formation and precipitation. This process aims to enhance rainfall or snowfall in a specific area.
Is a cirrocumulus cloud a rain cloud?
No. those clouds are to high to produce precipitation.
What may form when moisture condenses on small particles in the atmosphere?
AnswerWhen moisture condenses on small particles in the atmosphere, precipitation is formed. Depending on the chemical make up of the particles, the precipitation can have different effects. When the particles are composed of sulfur compounds, made from the burning of fossil fuels like coal, acid rain is formed and falls on the ecosystems below. Acid rain can drastically change an ecosystem by contaminating forests and freshwater resources.
What is precipitation in the form of small white ice crystals that form inside clouds?

What type of precipitation consists of small clear to translucent ice particles?
Sleet is a type of precipitation consisting of small clear to translucent ice particles. Sleet forms when raindrops freeze into ice pellets before reaching the ground.
A wintertime form of precipitation that consists of small ice particles is called?
the process is called precipitation when water returns from the atmosphere to the ground, this can be in the form of rain, sleet, snow or hale
Is aerosol a source of all clouds and precipitation?
All of the common clouds are a type of aerosol. Aerosol is a suspension of fine solid or liquid particles in a gas. That is where aerosol spray cans get their name. They produce an aerosol mist when their contents are released into the air. Obviously aerosol spray cans are not the source of all clouds and precipitation. They just produce a small cloud where they are used. When the material within an aerosol coalesces and becomes too heavy to stay in suspension, it precipitates out of the cloud. While most clouds, those made of solids or liquids, are aerosols, there are other types of clouds. Gas clouds are a high concentration of one type of gas within another gas or a vacuum. Some galaxies appear to be gas clouds. Plasma clouds share a similar definition. Lighting is a natural example of a plasma cloud.
What type of precipitation consist of small clear to translucent ice particles?
The type of precipitation that consists of small clear to translucent ice particles is called sleet. Sleet forms when raindrops freeze as they fall through a layer of cold air near the surface.
What do yellow clouds on radar mean?
Yellow clouds on radar typically represent moderate precipitation or rain. This level of precipitation is generally not as heavy as red or purple clouds, but can still result in moderate wet weather conditions.
What are second phase particles?
During precipitation hardening, few very small and uniform particles are added through compacting in order to improve the strength of the lattice. These particles are known as second phase particles.
