Is cloud a liquid or solid?

• Cloud is liquid.
• Clouds are formed in the Earth's atmosphere when water evaporates into vapor from oceans, lakes, ponds, and even streams and rivers
• The vapor rises up into colder areas of the atmosphere due to convective or frontal lifting.
• This subjects the rising air to a process called adiabatic cooling. The water vapor attaches itself to condensation nuclei which can be anything from dust to microscopic particles of salt and debris.
• Once the vapor has been cooled to saturation, the cloud becomes visible.
