a condensation nuclei
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.
Cloud formation typically comes first before precipitation. Moisture in the air condenses to form clouds as the air rises and cools. Once the clouds become saturated with water droplets or ice crystals, precipitation can occur when the droplets or crystals become heavy enough to fall from the clouds.

No. Tornadoes form from thunderstorms. By definition a tornado must make contact with both the ground and the cloud base. However, small whirlwinds, such as dust devils, can form on cloudless days. These look somewhat like tornadoes, but are nowhere near as strong.
It must collect enough mass in order for gravity to be able to turn it into a sphere.

The air must be moist.
Cool air and dust Particles
Water vapor and heat must be present for clouds to form. The water is evaporated from the ground and collected into a cloud.
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.
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.
Water vapour and heat. Wind is not necessarily needed to 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.
The plural form for the noun must is musts. The word must is also a verb, an auxiliary verb, and an adjective.
The changes to the rock must occur in solid form.
