Scientists Baffled by a Sudden Reversal Deep Inside Earth’s Core
A surprising reversal in molten iron flow beneath the Pacific is giving scientists a sharper view of how Earth’s magnetic field evolves. Earth’s magnetic field, the invisible shield that protects the planet from charged particles streaming from the Sun, is powered by a churning ocean of molten iron hidden thousands of kilometers beneath our feet. [...]
An abrupt change in the flow of liquid iron beneath the Pacific has caught the attention of scientists, who are now seeking to understand its implications for Earth's magnetic field. The research, published in the Journal of Studies of Earth’s Deep Interior, reveals that a vast region of iron-rich fluid has changed direction, shifting from a weak to a strong eastward flow. Change in the flow of liquid iron beneath the Pacific In 2010, a signific…
