Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent. While Wegener was alive, scientists did not believe that the continents could move. WebPrecambrian rocks must therefore be correlated by means of precise isotopic dating.

WebCorrelations of fossils and fossil assemblages have allowed geologists to identify rock units that formed during the same span of geologic time all over the world. The geologic time scale. Using fossil evidence, geologists developed the standard geologic time scale, which divides the earth's age into eons, eras, periods, and epochs (Table ). WebIf you pass one magnet (in a compass, say) near another, you'll see that they react to each other's magnetic field. In the same way, we can hold a compass near a magnetic rock and the compass will change direction to align itself with the rock's field. (What we actually do is, of course, a lot more precise than that, but that's the gist of it.) simplicity realty college station tx
