Venus in comparison with Earth

For a class

Venus in comparison with Earth

Venus in comparison with Earth

Yesteryear theories

Was believed to have been covered by tropical jungles
Wasbelieved to have same enviroment

Support of the hypothesis of escaping H

The ratio of H and Deuterium is 150 times as that of Earth
Deuterium being heavier cannot escape the atmostphere
Compared the amounts of H remains in the atmosphere with Deuterium

Size and composition

Is made of similar elements through out
Has about the same size

Enviroment

consists heavily of Water vapour
atmostphere is 100 times denser than Earth
Huge amount of atmosphere Carbon-dioxide
venus has turbulance

Lightning

On Earth, Lightning generates Radio waves
Differs from how lightning is produced on Earth

Reason for high temperature?

Due to water vapour that absorb heat
Due o high percentage of Green House Gases such as Carbon-Dioxide
Not because of closeness to the Sun

Water

Hydrogen escapes into space due to its lightness
Bright sunlight splits the water molecules into H and O
All the water , due to bright sunlight, evoparated resulting in a denser atmosphere
