Rocks are the natural building material of the Earth’s crust. They exist in the lithosphere down to depths of about 100Km and in the asthenosphere which exists as partially molten rock from about 100Km to 250Km in depth. The molten rock continues throughout the mesosphere to a depth of 2,900Km to the outer core which itself is partially molten rock, then to the inner core which is solid. At sometime or another rock emerges at the surface of the Earth as a result of the crystallization of volcanic lava, or material being uplifted by tectonic plate movement following rock formation slightly below the Earth’s surface. Classification of Rocks: There are three main types of rock along with many sub-types. The main types are described as follows.— 1. Igneous Rock. This type of rock is primarily formed by the crystallization of magma. Igneous rock can either be of volcanic origin (extrusive) or from beneath the Earth’s surface (intrusive or plutonic rock). Volcanic rock is formed at the surface of the Earth from the cooling and subsequent crystallization of lava, whilst intrusive rock crystallizes out just below the Earths surface by tectonic action. Granite is a good example of an igneous rock. 2. Sedimentary Rock. Sedimentary rock is composed of particles and materials from other rock types which have been weathered and eroded. Their continual accumulation results in them being formed into rock by a process of lithification. They can be turned into rock at the surface by the continual deposits from the sea or form from eroded rock beneath the surface. 3. Metamorphic Rock. This rock is formed when either an igneous or a sedimentary rock is subjected to high temperatures and pressure. They will form only under the surface of the Earth, and are brought to the surface by plate tectonic action.

Each individual state or country has its own methods of ensuring the security of confidential information, state affairs, and top-secret matters appertaining to internal and external security.

Each country will also have a classification of security levels which will determine which persons will have access to such confidential information.

Within the USA there are three main categories of classification –

Top Secret: This is the highest security level and it is deemed that any unauthorized access and leak of information with this degree of confidentiality would pose a large threat to national security. Such items may include –

There a number of worldwide rules which oversee the sales procedures and classification of wines, since each wine production area has its own method of assigning a name to the wine.

The classification or name of the wine is usually associated with both the place the wine was produced and the type of grape used for the manufacture. Most wines of European origin are named firstly by the region of production such as Chianti or Bordeaux, followed by the type of grape used, which may be a Riesling, Chardonnay, or Pinot.

What is entertainment? Entertainment is said to be a method of escaping from the humdrum of the routine daily activities and provides a way of gaining forms of amusement in either an active or a passive manner.

The classification of entertainments would form a very long list since the range of entertainments is far reaching and includes a variety of things which can be indulged in either by getting pleasure as a bystander or being an active participant.

Entertainments can include watching or taking part in sports events, going to the cinema or theatre, traveling to a concert or getting pleasure from practicing a hobby such as making your own videos on your computer from pictures taken with your digital camera.

Most frequently when people refer to the term classical music, they are talking either about types of music written between the early 19^th and 18^th century by the great composers, such as Bach, Beethoven, Mozart etc, or about any later music of similar style performed by an orchestra, ensemble, or as chamber music, but true classical music has much earlier deeper roots.

There are a few ways by which the classification of classical music can be considered and a few categories do exist, but it is difficult to make a positive classification since within each category of classical music there can be several themes. Here are a few of the categories. –

Being members of the phylum Chordate all fish possess a main dorsal nerve cord, a skeletal rod notochord, and paired gill slits. Their habitat is primarily the ocean, but they can also be found in inland rivers and lakes.

The classification of fish found around the globe falls into three main categories: Agnatha (jawed fish), Chrondrichthyes (cartiliginous fish), and Osteichthyes (bony fish, which include both ray and lobe finned fish).

-         Agnatha Fish. There are about 50 species of this type, which lack a jaw, paired fins, and any internal skeleton. In more ancient species they had bony skin plates which are no longer present in living species. The agnatha fish have up to seven gill pouches, but do not possess any form of stomach in their food digestive system. Both Hagfish and Lampreys are within this group.

An elementary particle refers to a constituent of matter which is incapable of being divided into a smaller particle. It is a fundamental sub atomic particle which includes such pieces of matter as electrons, leptons, hadrons, quarks, and photons.

The classification of elementary particles is based on which specific group of elementary particle they belong to and which kind of behavior they exhibit.

There is a group of particles referred to as Fermions, both Leptons and Quarks are included within this group. Any Fermions must follow what is known as the Pauli Exclusion Principle, which states that no two electrons within an atom can exist in the same energy state. That is, they cannot have the same four quantum numbers.

Any classification of diseases should include a break down of diseases which affect specific age groups, sex, and which are common to certain types of environment.

Classification of Diseases.

1.      Disease by Age. The body of children is continually growing and undergoing internal chemical changes associated with their natural development. The main center of such changes is associated with the development of the reproductive system which makes them more prone to diseases of the lymphatic system. These can become manifest as meningitis or hydrocephalus.

In the more elderly person they can be prone to such conditions as deafness or blindness, palsy, and afflictions of the bladder and bowel.

The periodic table forms the basis for the classification of elements. It comprises a list of all known chemical elements based on their Atomic Number. Commonly the periodic table classifies the elements into eight distinct groups depending on their chemical properties. –

-         Alkali metals.

-         Alkali earth metals.

-         Basic metals.

-         Halogens.

-         Noble gases.

-         Non metals

-         Transition metals.

-         Lanthanides.

-         Actinides.

Most people associate the chemical elements with being a metal or a non- metal, and since they occupy much space in the periodic table we will take a look at these two classifications of element.

Everyone enjoys watching TV, some more than others. Some people will watch almost any kind of program and even get some kind of entertainment from the ubiquitous ‘ads’, while other viewers tend to be a little more selective.

Any classification of TV programs will describe the two common types of program; the scripted variety and those programs which are supposedly unscripted (although doubts exist about the veracity of that!).

Whatever, any TV program either scripted or otherwise is either filmed live, or shot and recorded digitally in some form.

Within the unscripted class of TV shows certainly the presentation of sporting events are real. The participants in the event cannot be heard and the program presenters speak their commentary spontaneously as the sporting events unfold.
