The rainforest on Fatu-Hiva, Marquesas Islands is an example of an undisturbed

natural resource. Forest provides timber for humans; food and shelter for flora and

the fauna. The nutrient cycle between organisms form food chains and biodiversity

of species.

CONCEPTUALIZATION

Natural resources are resources in the environment that have not been disturbed

by mankind. By resource, one refers to any physical entity which has limited

availability. These resources occur in their natural form. Few examples are as

follows:

Air, wind, and atmosphere

Plants (Flora)

Animals (Fauna)

Agronomy (the science of using plants for food, fuel, feed, and fiber)

Wildlife

Forestry and Agroforestry

Coal and fossil fuels

Range and pasture

Soils

Water, oceans, lakes, and rivers

Something that people generally aren't aware of is that everything we use in

everyday life is derived from natural resources. For example, milk, which comes

from cows, vegetables that come from plants, salt which is a mineral, etc. Wood

that we get from tree is another example. It can be used to build a house, make

paper, burn in fireplaces and in stoves for cooking, etc.

Man utilizes these resources in various ways. They are processed further so as to

be made suitable for our needs. The table below is an example that shows in what

way the resources have been utilized:

Natural Resources Man-made Products

River Hydroelectric power

Petroleum Gasoline

ClamsClam chowder

Farmland Potato chips

PlantsMedicines

Here are a few natural resources and their uses:

Soil

Used for growing crops (only 10% of the Earth's surface).

Soil can be used for shelter. Many tribal people all around the world make shelter

with the help of soil.

Water

Used for drinking (only 0.0007% of Earth's water is suitable for drinking. The rest is

salt water, water trapped in glaciers, or polluted water.

Freshwater is used for irrigation of crops.

Water bodies such as oceans, lakes, and rivers of the world can be used for

transportation.

Fishing is a valuable source of food that is provided by water.

Water in rivers is being used to generate hydro-electricity.

Minerals


5/13

Minerals can be defined as naturally occurring substances obtained from the

ground. Some examples are coal, petroleum, natural gas, iron, copper, gold, etc.

They are also absorbed by plants from the Earth's surface, and are transferred to

humans through food.

They (coal, natural gas, and fossil fuels) are a source of energy.

Used as ingredients to make other materials like iron ore, minerals are also used to

make steel, and petroleum which is used to make a variety of products like

gasoline, plastics, etc.

Can be used in natural form like salt.

Vegetation

Land is used for farming from which vegetables and fruits are grown.

Wood from trees is cut and processed to make furniture for home.

Wood is used for cooking and also as fuel to produce heat for warmth.

Clothing - clothes are made from cotton.

Plants are used as an ingredient in medicines.

Animals

Animals are used as food, and their waste is used as fertilizers for crops.

We get fur and hides from animals which are used for making clothes.

Used for transportation.

These can further be defined as renewable and non-renewable resources.

Renewable resources are those that can be produced again, for example, plants

and animals, whereas, nonrenewable resources are those which cannot be

produced again, for example, fossil fuels.

We need to make serious attempts to use natural resources in an efficient manner

because in recent years, these resources have depleted as a result of their

careless use. The seriousness of the problem can be understood from the words of

former American president Theodore Roosevelt, "The conservation of natural

resources is the fundamental problem. Unless we solve that problem, it will avail us

little to solve all others."

Classification Natural Reosurces

There are various methods of categorizing natural resources, these include source

of origin, stage of development, and by their renewability, these classifications are

described below. On the basis of origin, resources may be divided into:

Biotic Biotic resources are obtained from the biosphere (living and organic

material), such as forests, animals, birds, and fish and the materials that can be

obtained from them. Fossil fuels such as coal and petroleum are also included in

this category because they are formed from decayed organic matter.

Abiotic Abiotic resources are those that come from non-living, non-organic

material. Examples of abiotic resources include land, fresh water, air and heavy

metals including ores such as gold, iron, copper, silver, etc.

Considering their stage of development, natural resources may be referred to in

the following ways:

Potential Resources Potential resources are those that exist in a region and may

be used in the future. For example, petroleum may exist in many parts of India,

having sedimentary rocks but until the time it is actually drilled out and put into use,

it remains a potential resource.

Actual Resources Actual resources are those that have been surveyed, their

quantity and quality determined and are being used in present times. The

development of an actual resource, such as wood processing depends upon the

technology available and the cost involved.

Reserve Resources The part of an actual resource which can be developed

profitably in the future is called a reserve resource.


7/13

Stock Resources Stock resources are those that have been surveyed but cannot

be used by organisms due to lack of technology. For example: hydrogen.

Renewability is a very popular topic and many natural resources can be

categorized as either renewable or non-renewable:

Renewable resources are ones that can be replenished naturally. Some of these

resources, like sunlight, air, wind, etc., are continuously available and their quantity

is not noticeably affected by human consumption. Though many renewable

resources do not have such a rapid recovery rate, these resources are susceptible

to depletion by over-use. Resources from a human use perspective are classified

as renewable only so long as the rate of replenishment/recovery exceeds that of

the rate of consumption.

Non-renewable resources are resources that form extremely slowly and those that

do not naturally form in the environment. Minerals are the most common resource

included in this category. By the human perspective, resources are non-renewable

when their rate of consumption exceeds the rate of replenishment/recovery; a good

example of this are fossil fuels, which are in this category because their rate of

formation is extremely slow (potentially millions of years), meaning they are

considered non-renewable. Some resources actually naturally deplete in amountwithout human interference, the most notable of these being radio-active elements

such as uranium, which naturally decay into heavy metals. Of these, the metallic

minerals can be re-used by recycling them, but coal and petroleum cannot be

recycled.

England is the largest, and most populous constituent country of the United

Kingdom of Great Britain and Northern Ireland. Its inhabitants account for

more than 83% of the total population of the United Kingdom, while themainland territory of England occupies most of the southern two-thirds of the

island of Great Britain and shares land borders with Scotland to the north and

Wales to the west. Elsewhere, it is bordered by the North Sea, Irish Sea,

Celtic Sea, Bristol Channel and English Channel.

England became a unified state in the year 927 and takes its name from the

Angles, one of the Germanic tribes who settled there during the 5th and 6th

centuries. The capital of England is London, the largest urban area in Great

Britain, and the largest urban zone in the European Union by most, but not all,

measures.

England ranks amongst the world's most influential and far-reaching centres

of cultural development. It is the place of origin of the English language and

the Church of England, and English law forms the basis of the legal systems of

many countries; in addition, London was the centre of the British Empire, and

the country was the birthplace of the Industrial Revolution. England was the

first country in the world to become industrialised England is home to theRoyal Society, which laid the foundations of modern experimental science.

England was the world's first modern parliamentary democracy and

consequently many constitutional, governmental and legal innovations that had

their origin in England have been widely adopted by other nations.

The Kingdom of England was a separate state, including the Principality of

Wales, until 1 May1707, when the Acts of Union resulted in a political union

with the Kingdom of Scotland to create the Kingdom of Great Britain

Geography

England comprises the central and southern two-thirds of the island of Great

Britain, plus offshore islands of which the largest is the Isle of Wight. It is

bordered to the north by Scotland and to the west by Wales. It is closer to

continental Europe than any other part of Britain, divided from France only by

a 24-statute mile (52 km or 21 nautical mile) sea gap. The Channel Tunnel, nearFolkestone, directly links England to the European mainland. The

English/French border is halfway along the tunnel.

Much of England consists of rolling hills, but it is generally more mountainous

in the north with a chain of low mountains, the Pennines, dividing east and

west. Other hilly areas in the north and Midlands are the Lake District, the

North York Moors, and the Peak District. The approximate dividing line

between terrain types is often indicated by the Tees-Exe line. To the south of

that line, there are larger areas of flatter land, including East Anglia and the

Fens, although hilly areas include the Cotswolds, the Chilterns, the North and

South Downs, Dartmoor and Exmoor.

The largest natural harbour in England is at Poole, on the south-central coast.

Some regard it as the second largest harbour in the world, after Sydney,

Australia, although this fact is disputed (see harbours for a list of other largenatural harbour).

Climate

England has a temperate climate, with plentiful rainfall all year round,

although the seasons are quite variable in temperature. However,

temperatures rarely fall below 5 C (23 F) or rise above 30 C (86 F). The

prevailing wind is from the south-west, bringing mild and wet weather to

England regularly from the Atlantic Ocean. It is driest in the east and

warmest in the south, which is closest to the European mainland. Snowfall can

occur in winter and early spring, although it is not that common away from high

ground. The highest temperature recorded in England is 38.5 C (101.3 F) on

August 10, 2003 at Brogdale, near Faversham, in Kent. The lowest

temperature recorded in England is 26.1 C (15.0 F) on January 10, 1982 at

Edgmond, near Newport, in Shropshire.

SYMBOLS OF ENGLAND

The three national symbols of England are the St. George's cross (usually seen

as a flag), the red rose and the Three Lionscrest (usually seen as a badge).

FRACTIONS:

In many situations we use the fractions as: Alejandro took 3 of the 9 pictures from

the poster; we express them like a fraction.

3 they are the pictures Alejandro too

9 total of pictures.

The terms of a fraction are: the numerator and denominator.

The numerator to indicate the number of part took.

The denominator to indicate the number of equal parts divided.

ADDITION AND SUBTRACTION OF FRACTIONARIES


13/13

To add or to subtract fractions with the same denominator, we add o to subtract the

numerators and let the same denominator.

Example:

2/3 + 5/3 = 2+5/3 =7/3

MILTIPLIYING OF FRACTIONES

To do this operation, we multiply the numerators among and denominators amongtoo.

Example:

x 3/2 = 1X3/4X2 = 3/8
