The dense atmosphere of Venus is light in color, causing most incoming solar radiation to be reflected.
<h3 /><h3>What is the composition of atmosphere of Venus?</h3>
The atmosphere of Venus is composed of carbon dioxide (CO2, 96,5 %) and nitrogen (N2, less than 3,5%) already represent more than 99,9% of the composition. Water Vapor is present in extremely low quantities, making Venus the driest planet of the solar system.
<h3>What is the effect of solar radiation on planet Venus? </h3>
On Venus, only 10% of the incoming solar radiation reaches the surface; most of it is reflected back into space by the planet's dense cloud cover, making Venus appear to shine brightly in the night sky.
Despite the small amount of solar radiation reaching the surface, it is trapped effectively by gases in lower atmosphere, giving rise to the high temperatures.
Scientists think that the Venus was once more like the Earth, but at some point it started heating up uncontrollably. Any water that may have once existed in oceans on the surface evaporated into atmosphere causing further runaway heating.
It’s like Earth gone wrong with a runaway greenhouse effect that some planetary scientists say should be a warning as to what may become of our home planet if human activities – such as burning fossil fuels and destroying forests, which intensifies natural greenhouse effect – continue.
