< p > "有没有地球大气层之间的交互和高速度在太阳风质子(如质子与大气中的氧气结合形成氢氧化物),能够平衡氢损失?”I found Hydrogen ions in the solar wind react with oxygen in interplanetary dust grains to form little packets of water, potentially supplying Earth with its water, but they don't know how much. "How big is the hydrogen loss?" 3 kilograms per second.
"Is the amount of hydrogen on Earth in equilibrium?" We are also gaining 50,000 tons of matter per year from space dust, but only a small part of that is hydrogen.
