Scientists Improve the Age Estimate of the Earth’s Inner Core
Inside a laboratory chamber at the University of Texas, researchers have created conditions similar to the center of the Earth. This mini-Earth has provided evidence that the earth’s solid inner core is at the younger edge of the possible spectrum. Here’s more from SlashGear:
…the new findings are significantly older than another recent estimate putting the earth’s core age at 565 million years.
The experiment also helps shed light on how the core conducts heat and how the energy sources that power the Earth’s magnetic field operate. The Earth’s magnetic field is critical for life on earth by protecting the planet from cosmic rays. The Earth’s geodynamo is something that scientists around the world are curious about because it contributes to the planet’s habitability.
