On Venus, outgassed water vapor from volcanic activity or other processes initially contributed to its early atmosphere. However, due to the planet's intense heat, the water vapor could not condense into liquid form and instead persisted in the atmosphere. Over time, the extreme temperatures and pressures led to the breakdown of water molecules through a process called photodissociation, where ultraviolet light from the Sun split water vapor into hydrogen and oxygen. The lighter hydrogen escaped into space, while the heavier oxygen likely reacted with surface materials, leaving Venus with very little water today.

Does Venus have a form of water?

yes. it is water vapor, which is a gas


What will happened to the water vapor in the air if the temperature drops as predicted?

When the temperature drops the less water vapor in the air


Does Venus have a source of water?

Venus is a hot and dry planet with no liquid water on its surface. Its high temperatures and runaway greenhouse effect have caused any water that may have once been on the planet to evaporate and escape into space. Although traces of water vapor have been detected in the atmosphere, there is no known source of liquid water on Venus.


Is there any water present in any form on Venus?

There is a small amount of water vapor in the atmosphere. It is far too hot for liquid water.


Which gas is present in the atmosphere of Venus Earth and Mars but not present in the atmosphere of Jupiter?

The gas that is present in the atmospheres of Venus, Earth, and Mars but not in the atmosphere of Jupiter is water vapor (H₂O). While all these planets have varying amounts of water vapor, Jupiter's atmosphere, dominated by hydrogen and helium, contains very little water vapor compared to the other three planets. This difference is significant given the role of water vapor in climate and weather patterns.


What was Venus thought to be covered with?

Venus is covered with clouds It's atmosphere is 92% carbon dioxide, 3% nitrogen, and there are small amounts of water vapor, argon, carbon monoxide, neon, and sulfur vapor. Venus is covered by clouds of sulfuric acid. The sulfuric acid rains down to Venus, but evaporates before touching the ground.


What happened to water vapor before it turned to water?

Water vapor is a gas once it has evaporated from liquid due to the cause of heat. After it turns into vapor, it will then travel up through the atmosphere and change back into a liquid.

What was responsible for supplying the early earth from water?

Water on early Earth is believed to have primarily come from cometary bombardment. Comets, composed of ice and rock, collided with the Earth and released water vapor that eventually cooled and condensed into liquid water. Additionally, water may have been outgassed from the Earth's interior through volcanic activity.


What happened to any water that may have existed on Venus?

it would have boiled away into the atmosphere
