Which chemical gases predominantly compose the atmospheric envelope of Jupiter?
Show answer Hide answer
Answer: C. Hydrogen and Helium
Explanation
Jupiter is a massive gas giant composed primarily of hydrogen and helium gas. These light elements make up the vast majority of the planet's immense atmospheric envelope. Deep within the planet, immense pressure compresses hydrogen into a metallic liquid state. Jupiter is the largest planet in our solar system, orbiting outside the asteroid belt. Spectroscopic analysis reveals the chemical composition of stellar and planetary atmospheres. The outer atmosphere features swirling cloud bands of ammonia crystals and water vapor.
Studying gas giant atmospheres helps astronomers understand planetary formation in solar systems. Spacecraft like Juno orbit Jupiter to measure its gravitational field and atmospheric composition. Jupiter's immense mass plays a gravitational role in shaping the architecture of our solar system. Chlorine is a reactive halogen gas found in trace compounds rather than bulk gas giant envelopes. Listing hydrogen alone ignores helium, which is the second most abundant gas in Jupiter. Neon is a noble gas present only in trace quantities within the Jovian atmosphere.
