Why are coal and petroleum are exhaustible natural resources?
The formation of fossil fuels is a very slow process, it takes millions of years. Hence, the amount of resources available for use is limited and is being exhausted by human activities like industrialization, rapid growth, etc. Thus, fossil fuels are exhaustible natural resources.
Is coal and petroleum exhaustible resource?
О Fossil fuels are exhaustible resources. О Coke, coal tar and coal gas are the products of coal. О Petroleum gas, petrol, diesel, kerosene, paraffin wax, lubricating oil are obtained by refining petroleum. О Coal and petroleum resources are limited.
Is petroleum exhaustible natural resources?
Answer : Petrol is a fossil fuel which is present in limited quantity in nature and can be exhausted by human activities but sunlight is present in unlimited quantity in nature and cannot be exhausted by human activities. So petrol is exhaustible natural resource, whereas sunlight is not.
Why coal is an exhaustible resources?
because coal is formed under the surface of earth. Fossil fuels require millions of years to form from the dead vegetation and animals that get buried deep inside the Earth. They require high temperature and pressure for their formation, which cannot be provided in the laboratory. Thus, fossils are limited.
What is the main use of coal and petroleum?
Coal is used in homes and industries as a fuel. It is also used to generate electricity in power plants. Petroleum products (such as petrol and diesel) are used as fuels in vehicles. Other products (like kerosene and LPG) are used as domestic fuels for cooking.
What is the importance of coal and petroleum?
Coal and petroleum are called fossil fuels. Coal and petroleum are the natural resources which are important ‘sources’ of energy for us. Coal is used as a fuel as such in homes and in industry, or it is used to generate electricity at Thermal Power Plants.
What is difference between coal and petroleum?
Basically, these differences center around the fact that coal is found at its site of deposition as a solid and relatively pure massive organic substance, whereas petroleum is liquid and migrates readily from its place of origin into porous reservoir rocks.
Is oxygen exhaustible or inexhaustible?
Oxygen in air is an inexhaustible natural resource, as it is present in unlimited quantity in nature and cannot be exhausted by human activities.
How do we get coal and petroleum?
Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.
Is Petroleum exhaustible or inexhaustible?
Examples – Coal, petroleum, etc. are the exhaustible sources of energy. Inexhaustible Natural resources – Inexhaustible resources of energy are those sources, which will not exhaust in future.
Why is petroleum considered an exhaustible resource?
Petroleum is an exhaustible resource as it is present in limited quantity. It cannot be replenished in a short period of time.
Why is coal inexhaustible in nature?
Such resources are called inexhaustible natural resources, e.g. air, water, sunlight, etc. … Such resources are called exhaustible natural resources, e.g. coal, petroleum, minerals, etc. Fossil Fuels: Coal and petroleum were formed from dead remains of plants and animals which got buried millions of years ago.
What is an example of an inexhaustible resource?
Inexhaustible Resources: Resources that have no practical limits, such as solar or hydrothermal energy. Air, wood, cotton, food, water, land, trees, fish, fertile agriculture, soils, crops and wildlife are renewal natural resources.
Why is coke considered a better fuel than coal?
Coke is a better fuel than coal because; –Coke produces more heat on burning than coal. -Coke has a higher calorific value than coal. … So, less air pollution is caused when coke is burned.
