What makes clouds white or GREY?

What makes clouds white or GREY?

It is the thickness, or height of clouds, that makes them look gray. Clouds are made of tiny droplets of water or ice. They are formed when water vapor condenses within pockets of rising air. When clouds are thin, they let a large portion of the light through and appear white.

What is the color of the clouds and why?

Clouds are white because light from the Sun is white. As light passes through a cloud, it interacts with the water droplets, which are much bigger than the atmospheric particles that exist in the sky.

Why do clouds appear GREY?

Basically, clouds look gray when they block out sunlight. A cloud gets thicker as it gathers more water droplets and ice crystals. The thicker a cloud gets, the less light can pass through it. So when you look up at a rain cloud, the base or bottom of it looks gray.

What causes clouds to look brown?

Atmospheric brown clouds are caused by emissions associated with the combustion of fossil fuels and biomass. The brown colour of the clouds results from the absorption and scattering of solar radiation by black carbon, fly ash, soil dust particles, and nitrogen dioxide.

Where does the color of the clouds come from?

Most color that we can see is visible because are eyes perceive how objects absorb or reflect certain wavelengths of light. The white colors of clouds come from the condensed water vapor having a high reflective quality. When all wavelengths of light are reflected back you see white. The grey color comes from seeing clouds from beneath.

Why are the clouds grey on a sunny day?

When all wavelengths of light are reflected back you see white. The grey color comes from seeing clouds from beneath. White clouds are white if you notice, on sunny days. This is because you can see the sunlight directly hitting them and see that light almost completely reflected back.

What makes a dark cloud appear in a photo?

Grey Clouds. In both the photos the clouds are about the same colour and brightness, but with a light background they look dark, and with the darker background they look white. Dark clouds are also caused by shadows by other clouds, or the cloud itself. A large cumulus cloud lit from behind will shade the surface seen by the observer,…

Why are clouds able to keep their shape?

You have to remember that in the upper reaches of the atmosphere that the temperatures are much colder. This means that water vapor once condensed can no longer return fully to its gas state. Since temperatures don’t change in this region clouds are able to keep shape longer. Finally, clouds have color.
