Can anyone tell me why clouds float and don't fall down ? tx
Doc Al said:Because the droplets of water are so small their terminal velocity is essentially zero. They are easily supported by rising air. When the droplets get too big, they do fall--as rain.
Clouds float in the sky because they are made of tiny water droplets or ice crystals that are suspended in the air. These particles are much lighter than the air molecules around them, causing them to rise and float in the atmosphere.
The water droplets or ice crystals in clouds are constantly moving and colliding with each other. This movement creates a force called updraft, which pushes the particles higher and keeps them from falling to the ground.
The size of the water droplets or ice crystals in clouds is very small, so they are easily lifted and carried by air currents. As they move higher in the atmosphere, they continue to grow in size until they become too heavy and fall to the ground as rain, snow, or other forms of precipitation.
The height at which clouds float is determined by the temperature, humidity, and air pressure in the atmosphere. Generally, the colder the temperature, the higher the clouds will float. Humidity and air pressure also play a role in determining cloud height.
No, different types of clouds can float at different heights in the atmosphere. For example, cumulonimbus clouds, which are associated with thunderstorms, can reach heights of 20,000 feet or more, while stratus clouds, which are flat and layered, typically float at lower altitudes.
