Which of the following is NOT a gas giant?

Saturn
Venus
Neptune
Uranus

The correct answer is: Venus

The correct answer is Venus, as it is classified as a terrestrial planet rather than a gas giant. Gas giants, such as Saturn, Neptune, and Uranus, are primarily composed of hydrogen and helium and have thick atmospheres without well-defined solid surfaces. In contrast, Venus is rocky, with a solid surface covered by volcanic plains and a dense atmosphere primarily made of carbon dioxide, with clouds of sulfuric acid. Understanding the classification of planets helps distinguish between their characteristics, such as composition and structure. Hence, recognizing that gas giants are vastly different from terrestrial planets like Venus is crucial in identifying them correctly.
