If you go to the troposphere - even though you know it's thousands of thousands of degrees hot you would freeze. And that's because even though the oxygen is still 21% the molecules in the troposphere are much fewer than in the thermosphere. I hope I helped!

What are we both doing up at this hour?
Combustion is fire. Oxygen is a component of combustion. Heat, oxygen and fuel (not oxygen) are required for fire. Take away any of the three and the fire stops. In your example you take away the source of oxygen so the candle is snuffed. Lava is heat, but not fuel. When something flamable get in the proximity of lava it tends to burst into flame due to the high heat and avalable oxygen. But the lava itself consumes no oxygen. What are some other possibilities for how volcanic eruptions aid in the creation of the atmosphere?
