Earthquakes: Tremors from Below
... How Do Scientists Study Earthquakes? Around five million people are affected by earthquakes every year - so it's not surprising that people want to know when the next big one will hit. But earthquakes are unpredictable. That's because there's no way to tell exactly when the rocks will snap from stre ...

Remnants of early Earth differentiation in today`s Earth
... Both the Moon and Earth show little lithophile evidence for 4.56 Ga differentiation. Instead, the 146Sm-142Nd data for lunar crustal rocks, mare basalts, and the Isua rocks with positive 142Nd anomalies suggest a global differentiation age in the circa 4.45 Ga range – similar to Pb ages for Earth. I ...

Observing Convection Currents
... Convection cannot take place without a source of heat. Heat within the Earth comes from two main sources: radioactive decay and residual heat. Radioactive decay, a spontaneous process that is the basis of "isotopic clocks" used to date rocks, involves the loss of particles from the nucleus of an is ...
