The part of the earth on which we live is the weathered crust of the lithosphere, the surface of our planet. Beneath the lithosphere are the mantle and the core of the earth. The crust is the exposed surface of the lithosphere that has been modified in various ways by climate and by ...
In other localities the coarseness of the soil does not materially change as we dig into it, but suddenly we come upon the surface of the bed rock, which may contain few if any of the constituents which were in the soil. This soil, which in no way resembles the underlying rock, is c...
It is not necessary to consider all the causes which may have disturbed the position of the rock layers, but the most important of them deserves attention. It has already been found that, although the exterior of the earth is cool, the interior is hot. Now it is known that almost all s...
If the crust(外壳)of the earth were not pretty solid(坚固的), it would be shaking and moving up and down frequently. However,there are places in the rocks of the earth's crust where it isn't strongly held together-where faults exist.Along the faults,one rock might push against another...

It was also found that soil water was not readily evaporated where the top of the soil was kept stirred, so that the little capillary tubes by which the soil water reaches the surface were broken and the sunshine and air were kept from the under part of the soil by a layer of finely ...
If the crust ( 外壳 ) of the earth were not pretty solid, it would be shaking about and moving up and down frequently ( 频繁地 ). However, there are places in the rocks of the earth’s crust where it isn’t strongly held together ― where “faults” exist. Along the break, one ...
