Without human assistance, natural resources are present on planet. We can get water, wood, food, and energy from natural resources. Without natural resources, life is not conceivable.Oil, coal, natural gas, metals, stone, and sand are examples of natural resources. Other natural resources include water, soil, sunlight, air, and so on.
Types of Natural resources:
two types of natural resources.
1.Renewable resources
2.non renewable resources.
1.Renewable resources:
A resource that can be used repeatedly and does not run out because it is naturally replaced.
examples of renewable resources are:
1.solar energy.
2.wind energy
3.GeoThermal energy.
4.Hydro power
5.Tidal energy
6.Biomass energy
1.Solar energy:
One well-known renewable resource is sunlight. In fact, throughout human history, it has been used to heat water, dry and prepare food, and warm habitations. In order to gather and transform solar radiation into heat energy that can be used for a variety of purposes, different technologies already exist and are being developed.
2.Wind energy:
The sun and wind are in a direct interaction. When the sun’s heat is absorbed unevenly by the various surfaces of the earth, including oceans and other water masses, daily winds are created. When the sun is shining during the day, air above land warms up more quickly than air above water. The warm air rises and expands. It is replaced with cooler air. The result is wind.In earlier years, windmills were used across the U.S. to capture energy and pump water from wells. They still exist in some farming areas to provide livestock with water.
3.GeoTheramal energy:
Geothermal energy uses the heat of the earth to produce electricity and is a renewable resource. For millennia, people have taken baths in hot springs that are heated by the ground. District heating systems have also utilised and continue to employ geothermal energy. Moreover, geothermal energy is used to produce power. Underground power plants are constructed for this purpose within a mile of the earth’s surface.
4.Hydro power:
A dam or other construction that alters the natural flow of a river or other body of water is used to generate hydropower, often known as hydroelectric power.Water in motion generates hydroelectricity, namely the winter and spring runoff from mountain streams and crystal-clear lakes. Water can be utilised to turn turbines and generators that produce power when it is falling due to gravity.
5.Tidal energy:
Tidal energy is a renewable source of power generated by the tidal movements and ocean currents that occur naturally. These technologies include paddles and turbines, among others. The rush of ocean waters during tide changes is what generates tidal energy. A renewable energy source is tidal energy.
6.Biomass energy:
A clean, renewable energy source is biomass. Plant or algae biomass may regenerate quickly since it receives its initial energy from the sun. Municipal solid trash, trees, and crops are all readily available and may be managed responsibly.
Advantages of renewable resources:
1.Low cost
2.clean,safe and efficient
3.numerous methods to create renewable power
4.Reliability and resilience
5.Less global warming.
Disadvantages of renewable resources:
1.Renewable resources need recycling.
2.initial cost is very high
3.renewable resources is not available at any time
4.It is difficult to generate the quantity of electricity.
Non Renewable resources:
The sources of non-renewable energy will deplete or not be renewed within our lifetimes, or perhaps within many, many lifetimes.
Examples of non renewable resources are:
1.Fossil fuels: coal, crude oil, natural gas
2.nuclear energy.
1.fossil fuels:
coal:
A flammable sedimentary rock with a high concentration of carbon and hydrocarbons, coal is often black or brownish-black in colour. Because it takes millions of years for coal to develop, it is categorised as a nonrenewable energy source. Coal is made up of the energy that was once locked up in plants that inhabited marshy forests hundreds of millions of years ago.
crude oil:
Only one non-renewable resource, crude oil, commonly known as petroleum oil, is extracted in liquid form. It is extracted by drilling a vertical well into the ground or ocean floor and is discovered between the layers of the earth’s crust or between rocks.
natural gas:
There are no renewable energy sources like natural gas. It takes millions of years for a fossil fuel to form. We can only manufacture more till a finite amount of it remains in the ground.
2.Nuclear energy:
The element uranium is the one that is most frequently employed in nuclear power reactors. Despite the fact that uranium may be found in rocks all over the world, nuclear power plants typically use U-235, a highly uncommon form of uranium. A non-renewable resource is uranium. Over the world, generating power via nuclear energy is a common practise.
Advantages of non renewable resources:
1.Non renewable resources are abundant and affordable
2.it is more effective and easier to produce and use then renewable energy
3.Non renewable resources are significant source of energy.
Disadvantages of non renewable resources:
1.These resources are used once.it can not be replaced.
2.once fossil fuels are burn.it creates pollution.
3.heavy uses of fossil fuels .it creates global warming and green house effect.
Most people know hypnotism or hypnosis as a party trick or a magic trick that magicians use to control you and make you cluck like a chicken or walk like a monkey. But what is hidden behind this facade is a rich history that dates back to ancient civilizations such as Greeks, Egyptians and Romans. In this article lets look at the science behind hypnotism.
Hypnotism is a practice that has been around for centuries. However it was during the 18th and the 19th century that hypnosis began to be studied and developed as a formal practice. The person to thank for bringing hypnotism to mainstream medical practice is Franz Anton Mesmer. He was an Austrian physician who believed that there was a magnetic fluid or force that flowed through the body and this force could be used to treat various medical conditions. He used techniques such as magnetic passes and “mesmeric” fluids to induce a trance like state in his patients, which he believed would help heal them.
In the 19th century another Scottish surgeon James Braid coined the term “hypnotism”. He was able to develop a more scientific approach to the practice. He developed techniques like eye fixation and verbal suggestion to induce a hypnotic state, similar to what we see and use in the present day. His belief was that hypnosis is a form of self induced concentration rather than a result of external forces and influences.
The use of hypnosis continued to grow throughout the 19th and the 20th centuries ,with many physicians and psychologist studying about it’s potential and using it to treat many mental issues such as anxiety and depression. Even Sigmund Freud who is regarded as the father of psychoanalysis was initially trained in hypnosis and he was a prominent figure in the field as well. But eventually he moved away from hypnosis as a primary tool in his practice and focused on developing his own method of psychoanalysis. Nevertheless, Freud’s early work in hypnosis paved the way for the use of hypnosis psychotherapy. However during the mid 20th century partly due to the rise in psychoanalysis and behavioral therapy the prominence of hypnosis reduced.
Again the 1950s and 60s saw the resurgence of hypnosis as a tool for managing pain and anxiety during medical procedures. Today it is widely used in clinical setting for a variety of purposes including weight loss, quitting alcohol and smoking, phobias, anxiety and stress.
The Science Of Hypnosis
The science behind hypnotism has been the topic of discussion and study for centuries but the exact mechanism of how hypnotism works is not yet fully understood. There are several theories that tries to explain the mechanism of hypnotism.
One main theory is the social – cognitive theory, this theory assumes that hypnotic state is a result of , a person’s willingness to be hypnotized and their level of suggestibility which is influenced by their beliefs and expectations about hypnosis as well as the social context in which the hypnotism takes place.
Another theory of hypnotism is the dissociation theory, it suggest that hypnosis involves a split or dissociation of consciousness, in which the hypnotized person is able to separate their conscious awareness from their unconsciousness. This allows a person to address their unconscious or underlying issues.
Resent research into the neuroscience of hypnotism suggests that hypnotic states are associated with changes with brain activity and connectivity , particularly in the areas of the brain that involves attention, perception and self-awareness. Some key areas of the brain involved in hypnotism are prefrontal cortex, which is responsible for functions like planning, attention and decision making, anterior cingulate cortex which is involved in attention and emotional processing and the parietal cortex responsible for spatial awareness and sensory integration. Neuroscience is a rapidly evolving field and ongoing research is helping shed light on the brain areas and network that is involved in maintaining and inducing hypnotic states.

There you go guys, hypnotism is more than just a party trick there is a long history and a clear science behind it. Through on going studies and researches scientists continue to explore and expand the potential of hypnotism as a tool for improving health, well-being and unlocking the mysteries of the mind.
