solid?????????

Answer 1

heyya dear...





Sand means different things to different

people. A genteral, non-technical

dictionary definition for sand is "loose

particles of hard broken rock". More

restrictive definitions als exist which

depend upon the frame of reference or

academic discipline to which the

meaning of sand is to be applied. For

example, to a sedimentologist sand is

an unconsolidated (loose), rounded to

angular rock fragment or minteral grain

having a diameter in the range of 1/16 to

2 mm (0.0025 to 0.08 in.). An engineer

on the other hand may restrict the

meaning of sand to include only

rounded framents having a diameter of

0.074 mm (retained on U.S. standard











"Stones are

primordial matter.

Sand is matter

ground by the infinity

of time. It makes one

mindful of eternity.

Sand is matter,

which has been

transformed and has

almost become

liquid and spiritual."













What Is Sand?



Practically, sand

may be considered to consist of small detrital fragments (rock or minteral

particles liberated by mechanical disintegration of parent rock material), biogenic

particles (shells or shell fragments) or chemical precipitates (evaporites or

oolites) occurring in nature and distinguishable by the naked eye.



A sand sample can be described in terms of grain size, color, composition,

morphology (angularity and shape) and surface texture. Grain size is a result of

several factors, including composition, durability, severity of weathering

conditions, transport distance from its site of origin, and physical sorting by wind

and/or water currents.



A variety of scales exist for measuring grain size. One which nearly all sand

collectors use, and the easiest to remember, is the "Wentworth Article Size

Classification for Sand", which uses a geometric interval of 1/2 to define the

limits of each size fraction. In descending order, the Wentworth sand

classification scheme is as follows:



Size limits of sand grains and other particulate material.



Size Class



Boulders



Gravel

a. Cobbles

b. Pebbles

c. Granules



Sand

a. Very course sand

b. Coarse sand

c. Medium sand

d. Fine sand

e. Very fine sand



Muds

a. Course slit

b. Medium slit

c. Fine slit

d. Very fine slit

e. Clay

f. Dust particles

0.156-0.031

0.0078-0.156

0.0039-0.0078

below 0.0039

These can be as small as

0.05 microns (0.0005 mm)



A population of sand grains examined at low magnification is often not uniform

as revealed by the occurrence of a mixture of grain colors, morphologies and

sizes. Whenever a wide range of grain sizes occurs withins a sample, the

sample is regarded as being "very poorly sorted." If there exists a very limited

variation in grain size within a population, the sample may be described as "very

well sorted." those samples have sorting characteristics between the extremes

will be graded as well sorted, moderately sorted or poorly sorted depending on

the range and relative percentages of grain size fractions.



Degree of angularity, also referred to as roundness, is a property that reflects the

formative processes (weathering, transport, abrasion and deposition) involved in

forming a sand deposit. Generally speaking, the more well rounded the individual

grain, the greater the energy involved in transport or the longer the duration of

transport. Sand grains in beach environments are subjected to high-energy

abrasion involving collisions with numberous other grains due to the action of

waves. Aeolian (eolian is an appropriate alternative spelling), are wind

transported sands also commonly well rounded by high energy collisions and

abrasion. Particles transported long distances by rivers or streams may also

achieve a high level of roundedness. Variations in the durability of different

mineral types also affect rounding.



Rounded particles may also form by precipitation in near shore ocean currents.

Ooliths are rounded grains formed by concentric precipitation of calcium

carbonate around a pre-existing particle such as a small shell fragment or quartz

grain that acts as a site of nucleation. They commonly form in areas where

strong bottom currents exist, such as tidal channels or near shore sites where

strong currents exist.



Degree of rounding or angularity defines one aspect of the shape of a sand

particle. A more complete characterization of particle shape requires

consideration of the way size differs (or remains the same) according to direction

within individual grains. Particles, which are tabular or shaped like a disk, are

said to be oblate. Equdimensional particles are called equant. Elongated and

somewhat flattened particles are bladed. Rod--shaped particles are prolate.



Surface texture refers to small-scale features of a sand grain's surface which have

no apparent bearing on its overall shape. Examples of surface textures include

polished and frosted. A polished texture is commonly observed on grains which

have been transported by water, and correspondingly are typically rounded.

Frosting is produced by collision with other sand grains and is commonly

observed in aeolian sands

Answer 2

Taking the battery out, while the phone is still on ( a power cycle) is the first thing you should do. It completely resets your phone to the network, getting rid of any bad tower signals you are receiving. A power cycle solves about 75% of all cell phone problems. However, most problems of this nature are a software issue and the phone will need an exchange. Also, while the battery is out check if the little sticker beneath the battery has turned red. If so, the phone is water damaged.

Answer 3

solid

though it contains of very small particals it is solid

Answer 4

solid

Answer 5

challenging problem. look into in yahoo and bing. that will might help!

Answer 6

complicated thing. check out with google or bing. that might help!

Answer 7

It has been proved to be both, it has the characteristic of both.
