Scientists hypothesize Earth’s early atmosphere was a result of outgassing from the interior of the planet. Gravity trapped the gasses (including NH3 and CO2) close to Earth’s surface. Over time, bacteria with the ability to perform photosynthesis changed the composition of the atmosphere. As plants evolved, levels of oxygen continued to increase as the levels of carbon dioxide decreased. The hydrosphere – primarily the ocean – played a major role absorbing carbon dioxide from the atmosphere. As plants grew on Earth’s surface, they weathered the geosphere producing soil. Microorganisms in the soil allowed for the evolution of land plants which also extended the boundaries for early animal populations.
As outgassing and volcanic eruptions created Earth’s early atmosphere, what two spheres directly affected one another?
Question 1 options:
Biosphere and geosphere
Hydrosphere and biosphere
