Because Earth has a weak gravitationalfield(by virtue of its size) and warm atmospherictemperatures(due to itsproximityto the Sun) compared with the giantplanets, it lacks the most common gases in theuniversethat they possess:hydrogenandhelium. Whereas both theSunandJupiterare composed predominantly ...
The first and most obvious clue about Pangaea's existence was that the "continents fit together like a tongue and groove," something that was quite noticeable on any accurate map, Murphy said. Another telltale hint that Earth's continents were all one land mass comes from the geologic record...
. The rocks of the lands disintegrate and rivers carry their wastage to the sea, where waves and currents spread it over the seafloor. There the layers of sedimentaccumulateone above the other, harden, and, in the course of time, rise from the bottom of the sea to form new continents. ...

Since the sea covers the greater part of the earth's surface,it is quite reasonable to regard the sea floor as the basic form of the crust of the earth,with,superimposed upon,it the continents,together with the islands and other features of the oceans.参考译文:既然海洋覆盖着地球的大部分...
more buoyant continents come together at convergent zones, they resist subduction and tend to buckle, producing greatmountainranges. TheHimalayas, along with the adjacentPlateau of Tibet, were formed during such a continent-continent collision, whenIndiawas carried into the Eurasian Plate by relative ...
