Which planet is made up of thick white and yellowish clouds of sulfuric acid?

  1. A.Uranus
  2. B.Venus
  3. C.Neptune
  4. D.Mars

Correct answer

B. Venus

Explanation

The correct answer is B, Venus. Venus is wrapped in a dense blanket of carbon dioxide topped by thick white and yellow clouds of sulphuric acid, which is why it shines so brightly in our sky. Those clouds reflect most of the sunlight that falls on them, giving Venus the highest albedo of any planet and making it the brightest object in the night sky after the Moon. The same blanket traps heat so well that the surface stays near 465 degrees Celsius, hotter than Mercury even though Venus is farther from the Sun. It is called Earth's twin for its similar size and mass, and the morning or evening star for when it is seen. Option A is wrong because Uranus looks blue-green owing to methane in its hydrogen and helium atmosphere. Option C is wrong because Neptune is also a methane-rich ice giant, known for its supersonic winds. Option D is wrong because Mars looks red owing to iron oxide dust and has a very thin atmosphere. Exam tip: Venus - hottest planet, thickest clouds, sulphuric acid, rotates east to west.

All three statements about latitude are true. Latitude decides how directly the Sun's rays strike a place, so temperature, rainfall and the type of vegetation change from the equator towards the poles, from hot, wet rainforests to cold tundra.
