Liquefaction is a term used in materials sciences to refer to any process which either generates a liquid from a solid or a gas, or generates a non-liquid phase which behaves in accordance with fluid dynamics. It is widely used in geology and engineering. Liquefaction occurs both as part of natural processes, and in man-made processes used in science and commerce.
For example, major ...

Gabbro refers to a large group of dark, often coarse-grained, mafic intrusive igneous rocks chemically equivalent to basalt. It forms when molten magma is trapped beneath the Earth's surface and slowly cools into a holocrystalline mass. Much of the Earth's oceanic crust is made of gabbro, formed at mid-ocean ridges.
Gabbro is also found as plutons associated with continental ...

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in heritable traits of a population over time. Natural selection acts on the phenotype, or the observable characteristics of an organism, but the genetic (heritable) basis of any phenotype that gives a reproductive advantage may become ...

A population is all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. The area that is used to define a sexual population is defined as the area where inter-breeding is potentially possible between any pair within the area, and where the probability of interbreeding is greater than the probability of ...

An anticline is a type of fold that is an arch-like shape and has its oldest beds at its core. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge.
Out of a number of ways, anticlines can be recognized and differentiated from anti-forms by a sequence of rock ...

Andesite is a type of igneous rock that is found in most volcanic regions of the world, especially around volcanoes that line the Pacific Basin. Its main mineral components are plagioclase, pyroxene, and hornblende. The study of andesite has helped scientists understand the geological processes by which this igneous rock can be formed.
Andesite is generally found as surface deposits ...

Anthracite is an example of a metaphoric rock. Also called hard coal, it is the most highly metamorphosed form of coal. It contains more fixed carbon (86 percent or greater on a dry, ash-free basis) than any other form of coal and the least amount of volatile matter.
Moreover, Anthracite has calorific values near 35 mega-joules per kilogram (approximately 15,000 British thermal units ...

Iron ore is a very common example of a sedimentary rock. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe2O3) and magnetite (Fe3O4).
The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to ...
