In the hypothetical situation that a given coastline has this property of self-similarity, then no matter how greatly any one small section of coastline is magnified, a similar pattern of smaller bays and promontories superimposed on larger bays and promontories appears, right down to the grains of sand.

This is because sand, like all powders and granular solids, contains a lot of air space in between individual grains.

Nor is the addition of a single grain of sand enough to transform a non-heap into a heap: when we have a collection of grains of sand that is not a heap, then adding but one single grain will not create a heap.

An opposite iterated technique, counting down rather than up, is found in the Sorites paradox, where one argued that if 1, 000, 000 grains of sand formed a heap, and removing one grain from a heap left it a heap, then a single grain of sand ( or even no grains ) forms a heap.

It forms as an evaporite, and is associated other evaporites such as calcite and halite ; if it incorporates sand grains as it crystallizes, gypsum can form desert roses.

Finally, once it has accumulated, the sand becomes sandstone when it is compacted by pressure of overlying deposits and cemented by the precipitation of minerals within the pore spaces between sand grains.

Framework grains are silicate grains that are detrital in origin, their purpose is to support the sand.

The porosity and permeability are directly influenced by the way the sand grains are packed together.

Aeolianite is a term used for a rock which is composed of sand grains that show signs of significant transportation by wind.

The sand is predominately made up of quartz grains.

Other methods commonly practised in Europe included severing the tendons at the knees or placing poppy seeds, millet, or sand on the ground at the grave site of a presumed vampire ; this was intended to keep the vampire occupied all night by counting the fallen grains, indicating an association of vampires with arithmomania.

The cilia allow the worms to glide along in the water between sand grains, although they also have muscles that allow the body to twist or contract.

It has a pair of muscular jaws supplied with minute teeth, and a plate on the lower surface that bears a comb-like structure which they use to scrape smaller organisms off of the grains of sand that make up their anoxic seabed mud habitat.

: Abundance of muddy matrix between sand grains

:: When sand-sized particles are deposited, the space between the sand grains either remains open or is filled with mud ( silt and / or clay sized particle ).

They are huge areas which have been swept by winds for so many centuries that there is no soil left, but only deep bare ridges fifty or sixty yards apart with ravines between them thirty or forty feet deep and the only thing that moves is a scuttling layer of sand.

The sand is fine and pleasant, the cabanas are clean, and the parasols, green, raspberry, and butter yellow, are very gay.

Today, abaci are often constructed as a bamboo frame with beads sliding on wires, but originally they were beans or stones moved in grooves in sand or on tablets of wood, stone, or metal.

Adobe structures are constructed with bricks created from sand, clay, and water, with some fibrous or organic material, shaped using frames and dried in the sun.

These anchors are only suitable for a silt or mud bottom, since they rely upon suction and cohesion of the bottom material, which rocky or coarse sand bottoms lack.

Consequently deadweight anchors are used where mushroom anchors are unsuitable, for example in rock, gravel or coarse sand.

The Black Sands, as the contrasting name would suggest, have a rockier and darker sand, and are also popular with visitors exploring the rock caves and fascinating sea life.

Submarine channels are similar to land rivers, but they are formed by density currents — underwater flow mixtures of sand, mud and water that are denser than sea water and so sink and flow along the bottom.

Some examples of habitats are ponds, trees, streams, creeks, and burrows in the sand or soil.

Newer problems include illegal beach sand extraction and overfishing while the nesting birds are vulnerable to introduced mammals including cats and rats.

However, the story is not yet quite finished: " When the thousand years have expired, Satan will be released from his prison and will go out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to battle, whose number is as the sand of the sea.

Very finely ground cements are made from mixtures of cement with sand or with slag or other pozzolan type minerals that are extremely finely ground together.

There are 33 sand Chicago beaches, a plethora of museums, two world-class conservatories, 16 historic lagoons, and 10 bird and wildlife gardens.

The vines are spread on the surface of the sand of the new bed and pushed into the sand with a blunt disk.

Paleodeserts are large sand seas now inactive because they are stabilized by vegetation, some extending beyond the present margins of core deserts, such as the Sahara, the largest hot desert.

There are no fewer than 152 beaches along its coastline — 50 kilometres of fine, white sand and 25 kilometres of black volcanic shingle.

The islands sand dunes and shoreline are home to a number of bee and wasp species including the large Eumenid caterpillar hunting wasp, Delta dimiatipenne and the striking blue banded bee, ( Amegilla cavifrons ).

Bullets were so thick, throwing sand in his face, that he found it difficult to return the fire.

Baltic amber or succinite ( historically documented as Prussian amber ) is found as irregular nodules in marine glauconitic sand, known as blue earth, occurring in the Lower Oligocene strata of Sambia in Prussia ( in historical sources also referred to as Glaesaria ).

Ambergris occurs as a biliary secretion of the intestines of the sperm whale and can be found floating upon the sea, or in the sand near the coast.

This affects the Mars colony and during the threat of a global sand storm, they found escape of the doomed outpost inside an alien pod, which carried the fugitive humans into a gigantic and espherical spaceship orbiting Mars.

The savannah zone's three categories are divided into mm ' Guinean forest-savanna mosaic, made up of plains of tall grass which are interrupted by trees, the most common across the country ; Sudan savannah, similar but with shorter grasses and shorter trees ; and Sahel savannah patches of grass and sand, found in the northeast.

Sometimes a layer of sand was put down, if it could be found.

This can also be found among sea urchins and sea cucumbers, where exhibit care for their young can occur, for instance in a few species of sand dollars who carry their young between the pricks of their oral side, and heart urchins possess breeding chambers.

The composition of drumlins varies depending on the area in which they are found, and can consist of similar material to the till of the surrounding moraine or be composed almost entirely of bedrock, sand and gravel or various mixtures thereof.

Heavy crude oil, which is much more viscous than conventional crude oil, and tar sands, where bitumen is found mixed with sand and clay, are becoming more important as sources of fossil fuel.

Once healed Władysław founded a Church of Holiest Virgin Mary " on the sand " in the spot where he found the cure.

In this case however, the fossils were found exposed in loose sand ; co-discoverer Beauvilain cautions that such sediment can be easily moved by the wind, unlike packed earth.

Similarly, he claimed that the anatase in the ink could have come from sand used to dry it ( the hypothetical source of the sand being gneiss from the Binnenthal area of Switzerland ) but his team had not examined the crystals microscopically, and Kenneth Towe responded that this was an essential test, given that crystal size and shape should clearly distinguish commercial anatase from anatase found in sand.

The sediment generally consists of coarse-grained, water-laid sand and gravel, although gravelly loam may be found where the rock debris is rich in clay.

In addition, great numbers of Harbour Seals and Grey Seals, the latters being rather uncommon in German seas, can be found on sand banks off Sylt.
