Earth air composition
WebThe first atmosphere was formed by outgassing of gases trapped in the interior of the early Earth, which still goes on today in volcanoes. For the Early Earth, extreme volcanism occurred during differentiation, when … WebThe atmosphere is rarely, if ever, completely dry. Water vapor (water in a ‘gas’ state) is usually present up to about 4% of the total volume depending on location. In the Earth’s desert regions (30° N/S) when dry winds are blowing, the water vapor contribution to the composition of the atmosphere will be near zero.
