Our Earth contains intense pressures and temperatures deep within its core. Because these conditions are so deep beneath the surface, though, scientists are still working on finding out exactly what processes occur. Now, they've discovered a little bit more about Earth's core and their findings may complicate theories of how our planet was formed.
"We know that Earth today has a core and a mantle that are differentiated," said Wendy Mao, one of the researchers, in a news release. "With improving technology, we can look at different mechanisms of how this came to be in a new light."
