# Dispersion ( usually named after Fritz London ), which is the attractive interaction between any pair of molecules, including non-polar atoms, arising from the interactions of instantaneous multipoles.

Dispersion is most often described for light waves, but it may occur for any kind of wave that interacts with a medium or passes through an inhomogeneous geometry ( e. g., a waveguide ), such as sound waves.

Dispersion in groundwater is because each water " particle ", passing beyond a soil particle, must choose where to go, whether left or right or up or down, so that the water " particles " ( and their solute ) are gradually spread in all directions around the mean path.

* Dispersion ( soil )

Dispersion occurs when pure plane waves of different wavelengths have different propagation velocities, so that a wave packet of mixed wavelengths tends to spread out in space.

Dispersion is an important concept in heterogeneous catalysis, since only atoms that are exposed to the surface are able to play a role in catalytic surface reactions.

Dispersion forces are usually dominant of the three van der Waals forces ( orientation, induction, dispersion ) between atoms and molecules, with the exception for molecules that are small and highly polar, like of water.

Dispersion of gravity – capillary waves on the surface of deep water ( zero mass density of upper layer, ρ ′ = 0 ).

Dispersion may be caused either by geometric boundary conditions ( waveguides, shallow water ) or by interaction of the waves with the transmitting medium.

( 2 ) Dispersion ( or disaggregation ) causes clay platelets to break apart and disperse into the water due to loss of attractive forces as water forces the platelets farther apart.

* Polyurethane Dispersion, a synthetic polymer dispersed in water

Although the term aeon may be used in reference to a period of a billion years ( especially in geology, cosmology or astronomy ), its more common usage is for any long, indefinite, period.

In geology and mineralogy, the term " carbonate " can refer both to carbonate minerals and carbonate rock ( which is made of chiefly carbonate minerals ), and both are dominated by the carbonate ion, CO. Carbonate minerals are extremely varied and ubiquitous in chemically precipitated sedimentary rock.

In various revised editions ( 12 in all, through 1872 ), Principles of Geology was the most influential geological work in the middle of the 19th century, and did much to put geology on a modern footing.

* Extension ( geology ), relating to the pulling apart of the Earth's crust and lithosphere

* Eridanos ( geology ), a large river that flowed between forty million and seven hundred thousand years ago from Lapland to the North Sea through where the Baltic Sea is now

In typical geological investigations, geologists use primary information related to petrology ( the study of rocks ), stratigraphy ( the study of sedimentary layers ), and structural geology ( the study of positions of rock units and their deformation ).

* Head ( geology ), a recent near-surface deposits

* Hotspot ( geology ), an area of unusually high volcanic activity

* Matrix ( geology ), the fine-grained material in which larger objects are embedded

* Mensa ( geology ), an extraterrestrial area of raised land

In 1842 he was appointed professor of mineralogy in the university of Dorpat ( Tartu ), and henceforth gave attention to the geology and mineralogy of the Russian Empire.

This comes after the studies of structural geology ( at the reservoir scale ), sedimentary basin analysis, reservoir characterization ( mainly in terms of porosity and permeable structures ).

* Prism ( geology ), a type of sedimentary deposit

* Rock ( geology ), naturally occurring solid aggregate of minerals and / or mineraloid

* Rock ( geology ), naturally occurring solid aggregate of minerals and / or mineraloids

* Shear ( geology ), the response of a rock to deformation usually by compressive stress and forms particular textures

* Tension ( geology ), occurs when a rock is pulled apart in two opposite directions

This branch of structural geology deals mainly with the orientation, deformation and relationships of stratigraphy ( bedding ), which may have been faulted, folded or given a foliation by some tectonic event.

He classified geologic time into primitive ( or primary ), secondary, and tertiary periods based on observations of geology in northern Italy.

The peninsula contains 3 main Sites of Special Scientific Interest ( SSSI ), both noted for their endangered insects and plants, as well as their geology.
