اقرأ أكثرThe age of the Earth calculated from these ratios is around 4.6 × 10 9 years. This is based on the assumption that the meteorites are also planet-like small bodies that have been formed in the solar system at the same time as our Earth. Conclusion: Radiometric age determination gives broader limits about the age of the Earth.
اقرأ أكثرA new study suggests that a hidden "ocean" is nestled in the Earth's mantle some 400 miles beneath North America. The hidden reservoir, apparently locked in a blue crystalline mineral called ringwoodite, may hold three times as much water that exists in all the world's surface oceans. This discovery may help explain where Earth's water supply ...
