why does Venus have such a high Albedo

Because its dense clouds scatter about 80% of the light received..

Correct. It is because of the clouds. They are made of low-absorbing liquid droplets -- mostly sulfuric acid. They are a bit more absorbing that earth's water clouds, but still have a high albedo.

Light that enters a dense nonabsorbing cloud is scattered back before most of it can penetrate through the cloud.

Venus has a high albedo because it is covered by thick clouds composed mainly of sulfuric acid droplets. Albedo refers to the fraction of sunlight that is reflected by a celestial body. In the case of Venus, about 70% of the sunlight that reaches its atmosphere is reflected back into space, resulting in a high albedo.

To understand why Venus has such a high albedo, you should consider the following factors:

1. Cloud cover: Venus has a dense atmosphere consisting mostly of carbon dioxide with traces of other gases like sulfur dioxide. These atmospheric conditions create a greenhouse effect, causing the planet's surface to heat up. As a result, the surface temperature of Venus is extremely hot, reaching up to around 900 degrees Fahrenheit (475 degrees Celsius). The high temperature leads to the evaporation of volatile substances like water, resulting in the formation of thick clouds of sulfuric acid. These clouds completely enshroud the planet, reflecting a significant portion of sunlight back into space.

2. Composition of clouds: The clouds on Venus are made up of sulfuric acid droplets, which are highly reflective. These droplets can scatter and reflect sunlight effectively, contributing to the high albedo. The presence of sulfuric acid in the clouds is due to chemical reactions in the atmosphere, where sulfur dioxide reacts with other substances.

So, in summary, the combination of Venus' dense cloud cover and the presence of highly reflective sulfuric acid droplets in those clouds results in the planet having a high albedo.
