Question

Gas Giants in our solar system are ________________

• A. Venus, Saturn, Uranus and Neptune
• B. Jupiter, Saturn, Uranus and Neptune
• C. Mars, Jupiter, Uranus and Neptune
• D. Saturn, Jupiter, Mars and Uranus

Hint:

To remember the planets in order from the Sun, use the mnemonic: "My Very Educated Mother Just Served Us Noodles" (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune). The first four are terrestrial (rocky) planets, and the last four are gas/ice giants.

Answer 1

The Correct Option is B

For a beginner, it's helpful to understand the basic classification of planets in our solar system. They are divided into two main groups based on their composition. Step 1: Understand the two types of planets.
Terrestrial Planets: These are the four inner planets closest to the Sun. They are smaller and primarily made of rock and metal. They are: Mercury, Venus, Earth, and Mars.
Giant Planets: These are the four outer planets. They are much larger and are composed mainly of gases and ices. These are: Jupiter, Saturn, Uranus, and Neptune.

Step 2: Define "Gas Giants". The term "Gas Giants" specifically refers to the giant planets. Jupiter and Saturn are true gas giants (mostly hydrogen and helium), while Uranus and Neptune are often sub-classified as "Ice Giants" (containing more water, ammonia, and methane ices). However, in general questions, all four outer planets are collectively referred to as the Gas Giants.

Step 3: Evaluate the options.
(A) is incorrect because Venus is a terrestrial (rocky) planet.
(C) is incorrect because Mars is a terrestrial planet.
(D) is incorrect because Mars is a terrestrial planet.
(B) correctly lists the four outer planets: Jupiter, Saturn, Uranus, and Neptune. Therefore, this is the correct group of Gas Giants.
