Rock structure affects landforms because different types of rocks are worn down by erosion at different rates. Some rock types are easily eroded, while others are more resistant. For example, we usually find weak rocks under valleys and strong rocks under hills, ridges, and uplands (Figure ). Among rock types, igneous rocks, sandstone, and ...

Such a packing arrangement with alternating layers would be designated as ABABAB. This ABAB arrangement is called hexagonal close packing (HCP). If the rows of atoms are packed in this third layer so that they do not lie over atoms in either the A or B layer, then the third layer is called C.

There are two types of interstitial sites in an fcc lattice. Let us consider a pair of layers blue and gold. Remember, the gold atoms cover all the leftpointing interstices in the blue layer, and none of the rightpointing ones. Under each gold atom is a small space surrounded by 4 atoms in a tetrahedral arrangement.

 · Both sedimentary and plutonic rocks are there found in conformable layers, and gold has been found in both, but the commercially available deposits are along and near the plane of contact of porphyry and limestone, but below the porphyry, the deposits thus being what is ordinarily described by miners as a contact deposit.

To use rock in engineering appliions, certain properties of the rock must be assessed to reasonably predict performance in the asbuilt condition. The properties of rock fall into two broad classes: rock material properties relating to the rock itself and rock mass properties relating to the inplace rock mass, including its discontinuities.

Gold is the most malleable of all metals. It can be drawn into a wire of singleatom width, and then stretched considerably before it breaks. Such nanowires distort via formation, reorientation and migration of disloions and crystal twins without noticeable hardening. A single gram of gold can be beaten into a sheet of 1 square metre (11 sq ft), and an avoirdupois ounce into 300 square feet ...

Some geologists can tell how old rocks are and determine how different rock layers formed (figure 2). There is probably an expert in almost anything you can think of related to Earth! Geologists might study rivers and lakes, the underground water found between soil and rock particles, or even water that is frozen in glaciers.
