How did volcanic outgassing effect earth’s first atmosphere?

Bryson Wright

Per. 2


  • Earth lost the gases hydrogen, and helium due to the suns radiation.

  • Earth has no atmosphere at this point.

  • The first atmosphere was formed by outgassing from the interior earth.

  • This process of outgassing still goes on today through volcanoes.

The Earliest Atmosphere


  • Extreme volcanism happened during this time when differentiation occurred.

  • Differentiation took place when heating and fluid-like motion in the mantle occurs.

  • It is believed that the main portion of the atmosphere was from degassing in the early stages of Earth.

three volcanoes

Factual Pictures


  • Hot spots are volcanic regions a few hundred kilometers across.

  • These spots are where main portions of outgassing occurs.

  • In the volcanoes, vents, which are linked to the magma chamber release the lava, water vapor and other gases such as sulfur dioxide, carbon dioxide and hydrogen.
