This document defines and provides examples of renewable and non-renewable natural resources. Renewable resources like oxygen, wood, and water can be replenished within human lifetimes through natural processes. Non-renewable resources such as coal, petroleum, and natural gas take significantly longer to form and are finite in supply, being non-renewable on a human timescale. The document cautions that renewable resources are not endless, and provides context on misconceptions around resource renewability.
Renewable and Non- renewable energy SourcesGeorge Thomas
Renewable energy is energy which is generated from natural sources i.e. sun, wind, rain, tides and can be generated again and again as and when required. Non-Renewable energy is energy which is taken from the sources that are available on the earth in limited quantity and will vanish fifty-sixty years from now.

Organic-Based Sources; Landfill Methane; Biomass energy; Hydropower ; Flowing water (Hydroelectric); Tidal power (waves and tides); Wave; Geothermal Energy (Geothermal power); Hydrogen Energy; Solar energy: (Energy from sunlight Rapid growing) ; Wind Energy
This is very basic presentation on Natural Resources.
It contains->
> Natural Resources.
> Its classification.
> Its extraction.
> Its depletion.
> Its conservation.
> Its Need.
This ppt is basic and is usefull for School and Engineering Students.
Non–renewable resources are those which once used up ,are exhausted, and are either non renewed by nature, or renewed very slowly over millions of years.
example-Fuels like coal and petroleum, and minerals like gold, iron and copper.
why is it important to save minerals-The mineral resources on the earth are non- renewable.
Once used up , they will not be available to us any more.
Mineral such as coal and petroleum , which give us fuels for providing energy , are being used up rapidly.
We should used this resources carefully and not waste them.
To save these minerals we should depend more on sources of energy that will never get used up, for example, solar energy and wind energy.

Soil, wood, oil. minerals, petroleum, water are considered natural resources because they occur in their natural form and are not made by human beings.Humans can only modify natural resources. The energy that makes natural resources comes from geochemical, geophysical and solar energy.
CONCLUSION
After discussing the advantages and disadvantages of the above resources it can be really a tough decision to point out the most suitable source of energy for the future. Although after thorough investigation of the above sources of energy it can be said that solar energy wind energy and biofuels are the leaders in this race for the favorable energy source for the future. It is an obvious fact that mankind could not survive with only these sources of energy. Scientists all round the world are trying to develop technologies to find alternative sources of energy. Nuclear fusion energy, fuel cell (H2O), plasma gasification of waste products are the arenas in which the future of mankind is dependent
In this lesson you will comprehend how the consumption of everyday p.docxmigdalialyle
In this lesson you will comprehend how the consumption of everyday products affects the availability of renewable and nonrenewable natural resources for future generations and learn about environmental threats to our home.
Read the following information to help you define three different types of resources—renewable, nonrenewable, perpetual.
1. On earth, there are only limited amounts of fossil fuels, such as coal, oil and natural gas. There are also only limited amounts of minerals, such as iron, copper and bauxite. These resources either cannot be replaced by natural processes or require millions of years to replenish.
2. Some renewable and nonrenewable resources can be recycled or reused. This process decreases the rate at which the supplies of these resources are depleted. For example, aluminum cans can be recycled and turned into “new” cans or other aluminum products many times over. Recycling reduces the need to mine bauxite, the mineral used to manufacture aluminum.
3. Renewable natural resources include plants, animals and water when they are properly cared for. Minerals and fossil fuels such as coal and oil are examples of nonrenewable natural resources.
4. Trees, wildlife, water and many other natural resources are replaced by natural processes. Plants and animals can also be replenished by human activities. Water is continuously cycled and reused. Sunlight, wind, geothermal heat, tides and flowing water are perpetual resources.
Water is a resource that is typically considered renewable. However, over usage of water can cause us to use it faster than it is replenished.
The chart below approximates daily water consumption in the United States:
1. Thermoelectric Utilities 187 billion gallons/day
2. Irrigation 137 billion gallons/day
3. Public Water Supply 36 billion gallons/day
4. Industry 26 billion gallons/day
5. Rural and Livestock 8 billion gallons/day
Total 394 billion gallons/day
What are the threats to our environment?
Biodiversity
Biodiversity is all of the Earth's plants, animals, ecosystems and genes. It includes the tallest tree, the smallest insect, and the most delicate coral reef ecosystem. Biodiversity is what allows the Earth and all of its creatures to adapt and survive.
As humans, we are completely dependent on biodiversity for survival. Yet we are destroying large parts of our natural world. In places far and wide, humans are squeezing out other forms of life, sometimes causing the extinction of entire species.
We have the power to change our course. Each of us can act to protect our biodiversity and help create a sustainable future for life on Earth. Learn more about biodiversity and how

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

3. Anything people can use
which comes from nature are known
as natural resources. People do not
make natural resources, but
gather them from the nature.
Examples of natural resources
are air, water, coal, etc.
Natural resources
4. Types of natural resources:
Renewable resources.
Non-renewable resources.
8. oxygen
As we all know human being
and animals use oxygen for
breathing , and plants
release oxygen, hence according to definition of
renewable resources oxygen is being
replenished so it is a renewable resource.
9. wood
Wood grows naturally and is
renewable. we use wood for
various purposes and it can grow
again for re-use and hence it is kind of a renewable
resource.
Example: timber.
10. water
Water continually moves
throughout the planet, with
each climate receiving its own
kind and volume of precipitation. If a
community overuses water, the source can
temporarily run out, but it will come back
eventually, followed by the definition
it is a renewable resource.
12. Non-Renewable Resources
A non renewable resource is a
natural resource that cannot
be re-made or re-grown at a
scale comparable to its
consumption.
14. Coal
coal is used as a fuel, it takes
millions of years to regenerate it, so
once we dig it all up, and, burn it, then
it's finished. it doesn't renew itself every day. if
somehow, a community uses, coal at a large scale
comparable to its consumption. it will run out, and
will have to wait for a long time, so that it will
regenerate for use, which is practically impossible,
so it is considered as non-renewable resource.
15. petroleum
This type of resources are
resources for which there is a limited
supply. So, The supply of
petroleum comes from the Earth itself and, as it
typically takes millions of years to develop and
is finite.
16. Natural Gas
Natural gas is the result of
decomposing plants and
animals that were trapped beneath
rock millions of years ago. So
once its used it takes a millions of time to
regenerate, so it is a non-renewable resource.
For example: Liquefied Petroleum Gas(LPG).
17. Misconceptions
Many people have the misconception that
a resource's status of renewability means
that it is an endless source. A renewable
resource is not endless; rather, the Energy
Information Administration (EIA)
defines a renewable resources as "Fuels that can be
easily made or 'renewed'."
