Structure:
- Evolution of Earth’s Atmosphere (Q1–6) — primordial H₂/He, solar wind stripping, degassification gases, why nitrogen stayed dominant (stable triple bond), rise of oxygen via photosynthesis, the “was it always there?” exam trap
- The Greenhouse Effect (Q7–12) — shortwave solar vs. longwave terrestrial radiation, which one heats the atmosphere, greenhouse gas list, benefits (Moon comparison) vs. global warming, full process sequence
- Atmospheric Gas Composition (Q13–16) — nitrogen 78%, oxygen 21%, argon vs. CO₂ ranking trap, roles of gases
- Distribution of Water on Earth (Q17–20) — 70/30 saline-fresh split, ice caps/glaciers (69%), groundwater vs. the common “rivers” mistake, the tiny 0.4% share
