Its a physical change because when clouds form, water vapor condenses into water crystals. That is a phase change which is also a physical change.
because condensation is simply just a change of the water temperature in the air. a temperature change is a physical change. clouds form when the water vapor condenses, so therefore, cloud formation is a physical change.
Original answer is INCORRECT. Clouds forming in the sky is a physical change because a chemical change requires a change in the chemical composition of a material and the H2O, no matter a solid liquid or gas, is always H20.
A physical change; more water vapour has joined the cloud, making it thicker and less able to allow light through.
When water evaporates into the sky it begins to get cooler and physically changes to condensation or clouds. This is important!!:)
No.
chemical change
Stratus Clouds form a layer or 'sheet' across the sky and tend to be much lower in the atmosphere
Lightning flashing across the sky is a physical change. It results from the movement of electrical charges in the atmosphere, without any changes in the chemical composition of the air or the resulting light.
The color of the sky being blue is a physical property, not a physical or chemical change. It is due to the scattering of sunlight by the Earth's atmosphere, particularly by air molecules and small particles in the atmosphere.
The cloud was a pillow in the sky.
Cloud base refers to the altitude above the ground at which the lowest portion of a cloud is observed. Cloud ceiling, on the other hand, is the height above the ground of the lowest cloud layer covering more than half of the sky. Cloud base is the specific altitude at which a cloud starts, while cloud ceiling is the overall height of the lowest cloud layer in the sky.
the clouds change colour due too presipiation and the density of the cloud
