Question

what did the atmosphere protect early earth from that helped life to develop?
solar radiation
meteorite bombardment
acid rain
pollution
banded iron formations (bifs) are evidence of
formation of water
formation of the solid geosphere
release of oxygen into the atmosphere
anthropospheric pollution

Explanation:

For the first question, the Earth's atmosphere helped protect early - Earth from meteorite bombardment by causing meteors to burn up upon entry. Solar radiation is not completely blocked by the atmosphere, and acid rain and pollution were not significant factors in early - Earth's development. For the second question, banded iron formations (BIFs) formed when oxygen reacted with dissolved iron in the oceans, leading to the precipitation of iron oxides. This is evidence of the release of oxygen into the atmosphere.

Answer:

1. B. meteorite bombardment
2. C. release of oxygen into the atmosphere
