The atmosphere of which planet is said to be made up of thick white and yellowish clouds of Sulphuric acid?

Correct option is C

The correct answer is (c) Venus

Explanation:
• The atmosphere of Venus is extremely thick and composed mainly of carbon dioxide (about 96%).
• It is covered by a dense layer of thick white and yellowish clouds composed primarily of sulphuric acid (H2SO4) droplets.
• These clouds are highly reflective, which is why Venus appears so bright in the sky.
• The thick atmosphere creates a runaway greenhouse effect, making Venus the hottest planet in our solar system, with surface temperatures high enough to melt lead.
• The atmospheric pressure on the surface of Venus is about 90 times that of Earth.

Information Booster:
• Venus is often called Earth's sister planet because of their similar size and mass, but their atmospheres are drastically different.
• In 2020, scientists detected phosphine gas in the Venusian atmosphere, sparking debates about the possibility of microbial life in the clouds.

Additional Knowledge:
(a) Mars (Option a)
• Mars has a very thin atmosphere, mostly carbon dioxide, but it lacks sulphuric acid clouds. It is known for its red dust.

(b) Mercury (Option b)
• Mercury has almost no atmosphere (only a thin exosphere), meaning there are no clouds or weather patterns.

(d) Neptune (Option d)
• Neptune's atmosphere is composed of hydrogen, helium, and methane, which gives it a distinct blue color, not yellowish clouds.
