Last week, we told you about a 7,500-square-mile raft of pumice discovered floating in the Pacific Ocean, but more recent observations by NASA reveal that chunks of the volcanic rock have since spread over an area of 100,000 square miles. So people are starting to wonder: What will become of the pumice?
Australian Naval officer Tim Oscar called the massive chunk of volcanic rock pictured up top "the weirdest thing [he'd] seen in 18 years at sea." Now, NASA satellite images have revealed the source of the floating raft: a mysterious undersea volcano known as the Havre Seamount.
We know that ancient organisms crawled out of the sea onto land, not the other way round. We know that the earliest life predates the existence of true continents. But life might just have began on land after all...sort of.
