The invisible part of clouds that you cannot see is water vapor and dry air. The majority of the cloud is just plain air in which the invisible water vapor is mixed with and the very tiny water drops and ice particles are suspended in. A cloud is a mixture of gas, liquid and solids.
Keeping this in view, what is in a cloud?
A cloud is a mass of water drops or ice crystals suspended in the atmosphere. Clouds form when water condenses in the sky. The condensation lets us see the water vapor. There are many different types of clouds. Clouds are an important part of Earth's weather and climate.
What are the three things you need to form a cloud?
Three things are necessary for clouds in the atmosphere to form: Moisture - There must be sufficient water vapor in the air for a cloud to form. Cooling air - The air temperature must decrease enough for water vapor to condense.
What is the Stratus cloud made up of?
Stratus clouds look like featureless gray to white sheets of cloud. They can be composed of water droplets, supercooled water droplets, or ice crystals depending upon the ambient temperature.
