Zorluk: OrtaThe Solar System and Planets

Astronomers categorize the outer Jovian planets into gas giants and ice giants based on their internal structure and atmospheric composition. Which of the following pairs of planets represents the ice giants due to having thick mantles composed primarily of heavier volatile substances such as water, ammonia, and methane?

  1. A
    Jupiter and Saturn
  2. Uranus and NeptuneCevap
  3. C
    Mercury and Mars
  4. D
    Jupiter and Uranus

Cevap

Uranus and Neptune are the ice giants of the solar system.
The pair comprising Uranus and Neptune is correct because both planets are classified specifically as ice giants. Unlike Jupiter and Saturn (which consist almost entirely of hydrogen and helium), Uranus and Neptune have interiors rich in heavier volatile elements and compounds—referred to astronomically as 'ices'—including water (H2OH_2O), ammonia (NH3NH_3), and methane (CH4CH_4).

Adım Adım Çözüm

1
Identify the distinct subcategories of outer Jovian planets
The outer solar system consists of two gas giants and two ice giants.
Planetary classification distinguishes between massive hydrogen-helium atmospheres and heavier icy compositions.
2
Examine the compositional makeup of each outer planet
Jupiter and Saturn are predominantly hydrogen and helium gas, whereas Uranus and Neptune contain substantial mantles of water, ammonia, and methane ices.
Ice giants formed in cooler, more distant regions where heavier volatiles condensed into solid/slushy mantles around rocky cores.
3
Select the pair that contains both ice giants
Uranus and Neptune represent the ice giant pair.
Both planets match the specific structural description given in the prompt.
