Zorluk: OrtaThe Solar System and Planets

Planetary scientists distinguish the planets in our solar system using unique atmospheric, structural, and rotational features. Which defining characteristic correctly pairs with each listed planet?

  • MercuryExperiences extreme day-to-night temperature swings due to having virtually no atmosphere
  • SaturnMaintains the lowest mean density in the solar system, which is less than the density of liquid water
  • UranusRotates nearly on its side due to an extreme axial tilt of approximately 98∘98^\circ
  • NeptunePossesses the fastest sustained atmospheric winds, reaching supersonic speeds

Cevap

Mercury matches with experiencing extreme day-to-night temperature swings due to having virtually no atmosphere; Saturn matches with maintaining the lowest mean density in the solar system; Uranus matches with rotating nearly on its side due to an extreme axial tilt of approximately 98∘98^\circ; Neptune matches with possessing the fastest sustained atmospheric winds.
Each planet exhibits a distinctive scientific signature: Mercury suffers drastic temperature variations because it has virtually no atmosphere; Saturn has the lowest bulk density of all planets (<1 g/cm3< 1\text{ g/cm}^3); Uranus features an extreme 98∘98^\circ axial tilt leading to sideways rotation; and Neptune produces the fastest sustained winds in the solar system.

Adım Adım Çözüm

1
Analyze the thermal and atmospheric properties of Mercury.
Mercury's lack of an insulating atmosphere causes massive swings between solar day and night temperatures.
Terrestrial bodies without gaseous atmospheres cannot retain heat through a greenhouse effect.
2
Evaluate the density and physical composition of Saturn.
Saturn's gaseous composition yields a mean density of roughly 0.69 g/cm30.69\text{ g/cm}^3, lower than water (1.0 g/cm31.0\text{ g/cm}^3).
Saturn has the lowest mass-to-volume ratio of all planets in the solar system.
3
Identify the rotational orientation of Uranus.
Uranus has an axial tilt of roughly 98∘98^\circ, causing it to rotate on its side relative to the ecliptic plane.
This extreme tilt produces unique, prolonged seasonal cycles.
4
Assess the meteorological records of Neptune.
Neptune features supersonic storms with wind speeds exceeding 2000 km/h2{}000\text{ km/h}.
Neptune holds the record for the most violent sustained atmospheric winds.
