WASHINGTON, April 22 (Xinhua) -- A new research published on Wednesday indicates that plate tectonics may have been well underway on Earth more than 3.2 billion years ago. The research added a new dimension to an ongoing debate about exactly when plate tectonics began influencing the early evolu...
Some of that heat is left over from the planet's formation, but most comes from the radioactive decay of unstable elements. Scientists deduce the Earth's deep internal structure by measuring how seismic waves from earthquakes propagate through it....
