- It was a weakly reducing atmosphere
- It was hotter
Explanation:
The primordial earth’s atmosphere was mainly composed of carbon dioxide and methane. These are greenhouse gases that kept the temperatures of the atmosphere high because they trap infrared radiation that reflects off the earth's surface. These gases also made the atmosphere a reducing atmosphere due to the absence of oxygen. The most likely source of carbon dioxide was frequent volcanoes at the time and the methane from early anaerobic microbes.
The atmosphere changed when photosynthetic organisms evolved and caused the Great Oxygenation Event because they evolved oxygen.

Question: <em>What is the life cycle of a common frog?</em>
Answer: A frog's life cycle follows along the path of egg, larva, and adult. To be more specific at what each stage is, the frog begins as an egg, laid in water by it's mother to keep the inside cool and hydrated. When it hatches after around fifteen days, it becomes a tadpole. It stays in the water continuing to grow, feeding on whatever lives down in that area. The frog must quickly understand that it is survival of the fittest as their mother doesn't stick around to feed them. After a good few weeks of them shedding their tail and growing working legs, the tadpole becomes a froglet. This stage of life allows them to become land animal; it will soon begin to transform into a frog. Once it does, it's finally off into the land of freedom, but a cruel one at that.
