I guess we should get to the questions!
01. What are clouds?
Clouds are water. Either large collections of tiny droplets of water or ice crystals that are so small and light that they can float in the air. There is also some warm air and a bit of dust involved.
02. How are clouds formed?
All air contains water, but near the ground it is usually in the form of an invisible gas called water vapor. When warm air rises, it expands and cools. Cool air can't hold as much water vapor as warm air, so some of the vapor condenses onto tiny pieces of dust that are floating in the air and forms a tiny droplet around each dust particle. When billions of these droplets come together they become a visible cloud.
03. Why Are Clouds white?
Clouds are white because they reflect the light of the Sun. Their water droplets or ice crystals are large enough to scatter the light of the seven wavelengths (red, orange, yellow, green, blue, indigo, and violet), which combine to produce white light.
04. What makes clouds turn gray?
Clouds turn gray when they get thick enough or high enough so all the light above does not make it through them. They look darker because of the lack of light coming through.. Also, if there are lots of other clouds around, their shadow can add to the gray or multicolored gray appearance.
05. What makes clouds move?
Clouds move because they are pushed along by the wind. They are so light that they float along, and any breeze can push them around.
06. Why do clouds float?
Clouds float whenever they are warmer than the air around them. They are made up of mostly water surrounded by a pocket of air that is warmer than the surrounding air. Warmer rises, and colder sinks.
07. Why do some clouds look very different than others?
Clouds look so different from each other because of the elements available, including the amount of water vapor, the temperatures at their particular height, the wind, and the interplay of other air masses.
08. Why do some clouds turn into rain clouds? Why does it rain?
It rains because as clouds rise higher and higher, the cloud's air gets colder and colder, and the water vapor in them gets heavier. When the water vapor in the cloud becomes too heavy, it falls back to the ground as rain or snow.
09. Why are even fluffy clouds flat on the bottom?
Clouds are flat on the bottom because the cloud isn’t just floating through the sky. It’s actually riding on top of a heavier layer of air! If you sit on something, you're flat on the bottom too.
10. How do clouds form thunder and lightning?
Clouds form thunder and lightning often at the end of hot, sticky summer days. At this time, warm moist air rises quickly and forms large cumulonimbus clouds. Inside these tall dark clouds, air currents create strong updraughts and water droplets and ice particles rub against each other. As they bang together like this, it causes a build-up of static electricity. Lighter, positive charges gather at the top of the cloud and heavier, negatively-charged pieces of ice and water accumulate at the base. The ground below is also positively charged. Electricity flows between the charges and the difference between them increases. When the differences get big enough, they are neutralised and electricity is released as a flash of lightning.
How did you like this interesting bit of trivia? Obviously we can't answer all questions in just one article, but if we get enough feedback and a lot of comments we might just revisit this subject with another ten questions.
