Interesting Fact:

The rock record, along with the fossil evidence and sediment it contains, holds many clues about the environmental conditions under which the earliest life forms evolved. For example, we now know that oxygen production began in the oceans at least 2.5 billion years ago and reached present-day levels in the atmosphere just 400 million years ago.
The climatic phenomenon known as El NiƱo is a disruption of the ocean-atmosphere system in the tropical Pacific.
