What is Natural Gas? Some Natural Resources Are Limited – Class 8 Notes

Natural Gas, Coal, and Petroleum are the major nonrenewable natural resources. These resources were formed millions of years ago from the dead remains of the living species. Natural gas is a type of fossil fuel made of gases found in nature and the major component of the Natural Gas is methane. Natural resources are things found in nature that people can use. They can be further divided into two types including renewable and non-renewable natural resources.

In this article, we are going to discuss Natural Gas in detail and further we will understand why Some Natural Resources Are Limited in the Earth.

Definition Of Natural Gas

Natural gas is the second largest contributor of the different greehouse gases to the climate. But it is also known as a clean fuel because it does not leave any ash when burned. People use natural gas for heating, cooking, electricity generation, and in different industries. It can also use to run the vehicles. Natural gas is found in the deep inside of the Earth, sometimes with the crude oil in porous sedimentary rocks.

Different Types Of Natural Gas

Before natural gas can be used, it is cleaned to remove things like water. During this process, other useful substances like ethane, propane, butanes, pentanes, and other chemicals are also separated out. These are the four main natural gases. They are the simplest types of gases found in nature as mentioned below.

Compound	Description	Uses
Methane	Simple gas found in natural gas	Heating, making electricity, cooking
Ethane	Gas used in making plastics and detergents	Making plastic items, detergents, and fuels
Propane	Gas used for heating, cooking, and fuel	Heating homes, cooking, powering vehicles
Butane	Gas used in lighters and portable stoves	Fuel for lighters, camping stoves, and heaters

Uses Of Natural Gas

Here are some major uses of the Natural Gas as mentioned below.

• Electricity generation: Natural gas is the main way we make electricity in the United States.
• Heating: Natural gas is used to warm buildings, water, and for cooking.
• Transportation: Natural gas is used as fuel in vehicles, with compressed natural gas (CNG) used in light, medium, and heavy-duty vehicles.
• Industrial: Natural gas is used as a heat and power source in factories, and to make chemicals and plastics.
• Manufacturing: Natural gas is used to create steam for making things in industries like steel and paper production.

What Is CNG?

CNG stands for Compressed Natural Gas. It is a fuel created by compressing natural gas to less than 1% of its uncompressed volume. Compressed Natural Gas (CNG), is natural gas under pressure. It remains clear, odourless, and non-corrosive in nature. It is also a cheaper, greener, and more efficient alternative to the traditional petrol and diesel fuels for vehicles.

Major Charcteristics Of CNG

Here are the Major Charcteristics Of CNG as mentioned below.

• CNG (Compressed Natural Gas) is a cheap, eco-friendly, and safe fuel made from abundant resources.
• Its mostly contains with methane with a few other gases.
• CNG cars are less reactive and emit fewer pollutants compared to gasoline cars.
• They operate similarly to regular cars with spark-powered engines.
• Natural gas is compressed at stations before use.
• Benefits of using CNG include lower transportation costs and reduced carbon emissions.

Difference Between CNG vs LPG

Here are the major Difference Between CNG vs LPG as mentioned below.

Aspect	CNG (Compressed Natural Gas)	LPG (Liquefied Petroleum Gas)
What It’s Made Of	Mostly methane	Propane and butane
Where It Comes From	Comes from natural gas	Comes from refining crude oil or natural gas
How It Is Stored	Compressed to a small size	Stored as a liquid under pressure
Common Uses	Used for vehicles and some industries	Used for heating, cooking, and vehicles
Environmental Impact	Produces fewer emissions than gasoline and diesel	Produces fewer emissions than traditional fuels
Storage and Handling	Requires special tanks and refueling stations	Requires special equipment for handling and storage
Ease of Transport	Needs special infrastructure for transport	Can be transported more easily than CNG

Some Natural Resources Are Limited

Some resources are renewable. It means they can be replaced over time, like sunlight or wind. Others are non-renewable including coal and oil. They can not be replaced because they took millions of years to form. Here are some major factors why Some Natural Resources Are Limited and we have to save them.

• Natural resources like oil, gas, and minerals take millions of years to form.
• They come from processes like decomposition, volcanoes, and movements in the Earth’s crust.
• These processes are slow and we only have limited amounts of these resources.
• Things like climate, land, and soil quality affect what resources are available.
• Pollution and climate change make these problems worse by reducing the amount of usable resources.
• Humans are using up resources faster than ever because of things like factories, cities, and more people.
• This is causing damage to forests, oceans, and mineral deposits that can’t be fixed easily.
• Technology helps us get resources out of the ground faster, but it also hurts the environment.
• Money also plays a big role. When more people want something, its price goes up. This can lead to fights over resources.
• Companies often care more about making quick money than saving resources for the future.

FAQs – Natural Gas And Some Natural Resources Are Limited Class 8 Notes

Why natural resources are limited Class 8?

Fossil fuels such as coal, petroleum and natural gas take millions of years to form naturally. They cannot be replaced as fast as they are being consumed.

What is natural gas short note for Class 8?

Compressed Natural Gas is a very essential fuel since it is easy to transfer through pipes and can be compressed and stored under high pressure. It does not pollute the environment and has a high calorific value. CNG is utilised to generate electricity. It is now used as a transportation vehicle fuel.

What are natural resources Class 8 notes?

Natural Resources are extracted from nature and are mainly utilized without making any change in their form. For example, air, water, minerals, etc. Man Made Resources are the ones which are made by humans. They are derived from natural resources but are not used in their original form.

What are some natural resources limited Class 8?

Exhaustible natural resources are resources which are limited in nature and can be exhausted by human activities. Examples include forests, wildlife, minerals, coal, petroleum, natural gas etc.

How do natural resources become limited?

Natural resources are those that the planet offers without the need for human intervention. They are essential our survival, but if they are consumed at a faster rate than their natural regeneration, as is currently the case, they can be exhausted.

Are natural resources in limited supply?

Nature does not produce an unlimited supply of natural resources due to various factors inherent in the Earth’s natural processes and limitations.

What is the formula for natural gas?

In its pure form, natural gas is a colorless, odorless gas composed primarily of methane. Methane, the simplest and lightest hydrocarbon, is a highly flammable compound consisting of one carbon atom surrounded by four hydrogen atoms (chemical formula: CH4).

What are the 4 main gases in natural gas?

The four natural gases and include the first four alkanes — methane, ethane, butane, and propane. An alkane is a hydrocarbon where single bonds link together each atom. Hydrocarbons are chemical compounds made up exclusively of carbon and hydrogen atoms.

How is natural gas sold?

Compressed Natural Gas or CNG is sold at the retail level either by mass, energy units or “gasoline gallon equivalents” or gge. The National Conference of Weights & Measurements (NCWM) has developed a standard unit of measurement for compressed natural gas.
