Atmospheric Composition
The atmosphere's composition varies significantly based on climate, with dry air consisting of 78% nitrogen and 21% oxygen. While the theoretical boundary of the atmosphere is around 8.5 km, its density decreases exponentially with altitude, making it difficult to define where space truly begins. The Karman line, set at 100 km, marks the conventional start of space, but the atmosphere continues to thin indefinitely beyond that point.In this clip
