How cloud are formed?
Answers
Answer:
clouds form when moist, warm raising air cools and expand in the atmosphere
Answer:
When the sun shines over rivers, lakes and oceans of the world it heats up the surface of the water.
The water turns into gaseous water vapour on being heated and begins to rise into the air.
As it goes higher, the water vapour begins to cool down and turns back into water droplets.
The temperature at which water condenses is called the dew point.
The dew point is not a constant because it depends on the amount of water present in the air.
These water droplets in clouds are so tiny that they hang suspended high up in the earth's atmosphere.
Over a period of time condensed water vapour accumulates to form clouds.
The water droplets higher up in the cloud are colder than the droplets below to the extent that some parts of a cloud can even contain small bits of ice.
After a while the cloud becomes heavy with water droplets and gravity brings the water droplets back down as rain.
Clouds appear white because they allow light to pass through.
Since sunlight is white, the water droplets simply act like a canvas upon which the sun throws its rays.
When trillions of water droplets get together in one cloud, they allow less and less light to pass through it thus giving it a dark gray hue.
This is also how we know that it is about to rain
